ABSTRACT

One of the most important groups of soil microorganisms is the mycorrhizal fungi. Sixteen species of VAM fungiwere reported by me and my team from forest tree species of South India. Fifteen VAM fungal species were isolated from burned area and 16 species from the unburned area. It was found that VAM fungi are affected adversely by the intensity of the fire but they recover from a burn within 2 years. The VAM fungal association with the plant species colonizing a magnesite mine spoil was investigated and 13 VAM fungal species were identified.  Spores of GlomusfasciculatumandGigasaporagiganteawere commonly found in the magnesite mine spoil. The mycorrhizal fungi in the epiphytic and terrestrial orchids were studied and 5 AM fungal species were identified. For the first time, Pisolithustinctoriushas been reported by me and my team in tropical region in association with Eucalyptus tereticornis. Investigation on mycorrhizal association in Casuarinaequisetifoliagrown in 4 different soil types was carried and it revealed a total of 10 species of Glomus, 2 of Gigaspora and 2 of Sclerocystis. Investigation on the mycorrhizal and actinorhizal status in C. equisetifolia at 25 sites in and around coastal region of Madras, Tamil Nadu revealed the presence of total of 8 species of VAM fungi and it has been found that the dual inoculation (Frankiaand Pisolithustinctorius) gave more biomass than individual inoculation.It was shown thatPisolithustinctorius and Laccarialaccata exhibited higher amounts of IAA production than other fungi, whereas Amanita muscaria and Rhizopoganluteolus showed least quantity of IAA. The growth and acid phosphatase activity of L.laccata has been studied and it has been found that L. laccata was more tolerant to Cu than Ni and increasing Cu and Ni concentration induce the increase of acid phosphatase activity (maximum at 0.15 µm) in L. laccata. The axenic growth, total protein content and acid and alkaline phosphatase activities in Amanitamuscaria was estimated and it has been found that A. muscaria was also more tolerant to Cu than Ni. Among L. laccata and Suillusbovinus, L. laccatahad maximum acid and alkaline phosphatase activities and tolerance to high concentration of chromium.Casuarinaequisetifolia seedlings were raised in glasshouse condition and inoculated with suspension of pure culture of Frankia. The nodules have been collected and analysed for the presence of cytokinin and significantly the cytokinin has been detected in the nodules. Significantly increased GA has been demonstrated in roots, nodules and cladodes of triple (Glomusfasciculatum, Pisolithustinctorius and Frankia) inoculated plants of Casuarinaequisetifolia. Maximum amounts of IAA in cladodes and roots of C.equisetifoliahave been established byHPLC analysisin triple (Glomusfasciculatum, Pisolithustinctorius and Frankia) inoculated plants than the other individual treatment of symbiont. Higher content of IAA in nodules of Glomusmosseae and Rhizobium inoculated Prosopisjuliflora has been demonstrated. Sodium alginate beads of Laccarialaccatawere prepared and the beads were viable for 10 months. The fungal hyphae in the beads formed mycorrhizal association with Eucalyptus tereticornisand enhanced growth has been demonstrated in the seedlings due to mycorrhizal association. Spores of Scutellosporaerythropa and Scu.nigra isolated from neemrhizosphere soils from coastal regions of Chennai, India were tested for axenic germination in in vitro conditions. They showed positive results in media of different composition using root exudates, soil extract, thiamine HCl and inositol. The combined medium increased the spore germination in Scu. erythropa and in Scu. nigra over water agar control. The germ tube often grew up to 3.8 cm on combined media but no vegetative spores and extramatrical auxiliary cells were observed during the experiment. There was significant increase in hyphal growth when the roots were introduced into the medium, 3 days after spore germination. Based on the method developed, growth of Glomusmosseaeand Gigasporagiganteaonin vitro root organ culture of Sorghum vulgareand Saccharum officinarumwas carried out.Spores of Gl. mosseae and Gig.gigantea germinated on minimal medium produced extraradical mycelium. Gl. mosseaeinfected roots of S. officinarum in in vitro condition were inoculated in minimal medium with in vitro cultured roots of Sorghumvulgare (test roots). From the infected root of S. officinarum, the mycelium developed and it infected the test roots. The roots developed new mycelia and further the mycelia produced a few hyaline spores. In MS medium combined with soil extract, root exudate, thiamine HCI and inositol combination, spore germination and germ tube growth were higher when compared with other media. Thus, significant contributions on the biodiversity of Indian mycorrhizal fungi and application of mycorrhizal fungi for growth improvement of plants were made.

ABSTRACT

Arbuscular mycorrhizal (AM) fungi are obligate symbionts belonging to the phylum Glomeromycota that enhance host plant growth through nutritional benefits.AM fungal propagules exist as spores, living hyphae, isolated vesicles, and mycorrhizal root segments. The present study reports establishing an in vitro culture of Glomusclarum using mature vesicles grown monoxenically with Ri T-DNA transformed Cichoriumintybus L.(chicory) roots. Upon inoculation, 90% germination was recorded in vesicles after 36 h in theModified Strullu and Romand (MSR) medium. Germinated vesicles were transferred to 9 cm diameter Petri plates (one vesicle/plate) containing 15 days of actively growing Ri T-DNA transformed chicory roots and incubated in the dark at 26°C. Sporulation was observed after five weeks of inoculation. The study suggests that isolated vesicles constitute an excellent source of inoculum for initiating successful in vitro culture of G. clarum.

ABSTRACT

Candida albicans is an opportunistic human fungal pathogen causing candidiasis in immune-compromised patients. C. albicans is resistant to the existing drugs and exists on abiotic and biotic clinical surfaces, making it difficult to control. The biofilm formed by these fungi leads to multiple hospital-acquired fungal infections. Silver nanoparticles arereported for their antimicrobial activity and absence of resistance. Hence, the study aims at the application of silver nanoparticles against C. albicans and its biofilm formation. The synthesized AgNPs were ~ 37 nm, having a -37 mV charge. This process gives a yield of 880 µg/mL of AgNPs. These nanoparticles displayed antifungal activity against C. albicans with 2.97 µg MIC. Coating the coverslip with silver nanoparticles showed efficient inhibition of the biofilm formation by C. albicans with 97.51% inhibition by fluorescence microscopy. Impregnation of catheter surfaces with 1, 2, and 3 layers of silver nanoparticles showed 7.51, 15.23, and 43.02% reduced viability of Candida by MTT assay, respectively. The luminol assay could attribute the efficiency of AgNPs to their ROS generation. Moreover, the nanoparticles were non-cytotoxic. Hence, the silver nanoparticles exert antimicrobial activity, and their coating on catheter surfaces can show the antifungal effect on C. albicans biofilm formation.

ABSTRACT

Ginger is one of the cash crops grown worldwide, and consumed daily as a spice food, and utilized as Ayurvedicmedicine. Soft-rotor rhizome-rot, is a major rhizome-deteriorating fungal disease caused by various fungi like Fusarium spp. and Pythium spp. in ginger, leading to huge yield losses and economic losses. This study reported in vitroantifungal activity of Phomaherbarum,cell-free extract-mediated copper oxide nanoparticles (CuONPs) against Pythium and Fusarium isolates from soft-rot infected ginger, identified at the genus level microscopically. CuONPs were detected by a visible color change from blue to dark brick red precipitate and characterized by Ultra Violet (UV)-visible spectrophotometry (absorbance maxima at 630 nm) and Nanoparticle Tracking Analysis (average size 83 nm). Stability was confirmed by Zeta potential measurement (-23.5 mV), and Face Centered Cubic crystalline structure was elucidated by X-ray diffractometry, and roughly spherical crystals were visualized by Field Emission Scanning Electron Microscopy (FESEM). Fourier Transform Infra-red (FTIR) spectroscopy showed the presence of various functional groups that stabilized CuONPs. The in vitro study showed significant antifungal activity of mycogenicCuONPs against test fungi, which was substantially comparable with a chemical fungicide,i.e.,mancozeb. Accordingly, the findings supported the application of mycogenicCuONPs as a cutting-edge antifungal agent in the direction of sustainable agriculture.

ABSTRACT

Humans depend on many different plants as food sources, and since ancient times, cereals have been the most important. Cereals are a nutritionally important source of dietary proteins, iron, vitamin B complex, vitamin E, carbohydrates, niacin, riboflavin, thiamine, fiber, and traces of minerals essential for both humans and animals. Arbuscular mycorrhizal (AM) fungi are soil fungi that form a mutualistic symbiosis with the roots of plants. The review summarizes recent research on AM fungal symbiosis in crop plants. It also provides a comprehensive knowledge of AM fungi, their influence on crop plants at various stages of growth, their role in improving yield and productivity, increased tolerance to various environmental stresses, and their effect on agricultural management practices.

ABSTRACT

Arbuscular mycorrhizal fungal association in relation to edaphic and climatic factors was assessed in eight plant species viz., Chromolaena odoratum, Emilia sonchifolia, Mimosa pudica, Ludwigia parviflora, Ischaemum semisagittatum, Acacia auriculiformis, Acacia mangium, and Trema orientalisfor one year from Codli iron ore mine reject dump in Goa. Arbuscular mycorrhizal (AM) colonization levels and spore numbers varied significantly between the plant species in the different seasons. The calculated correlation coefficient showed that soil moisture was negatively correlated to EC, N, P, K, calcium, organic carbon, and organic matter. Soil moisture had a positive influence on AM fungal colonization and a negative influence on spore density in all the plant species. Spore number was maximum in pre-monsoon and least in monsoon, while AM colonization was maximum in monsoon and least in pre-monsoon. A total of 40 AM fungal species belonging to 13 genera were reported during the study. Among the genera, the genus Glomus was dominant in the pre-monsoon,Acaulosporawas dominant in the monsoon, and Gigaspora was dominant in the post-monsoon season.

ABSTRACT

Spent mushroom substrate is not being effectively used and is true for Oyster mushroom spent substrate. Thebio-based material that is produced after the growth of fungal mycelium in substrates such as paddystrawcan be usedinconstruction industry, for packaging purposes as a sustainable alternative to petroleum-based plastic packaging, as biodegradable containers and flower pots. Culturablemushrooms are good candidates for preparation of biomaterials from spent substrate. In the present study it was found the Pleurotusostreatus, cultured from fruit bodies available in the market and P. tuber-regium, obtained from the wild, are suitable candidates for production of such bio-materials since they were found to colonize the substrate,  paddy straw, and form a good composite material with the substrate. The identity of wild P. tuber-regium was confirmed by ITS rRNA gene sequencing.

ABSTRACT

Production of pecticlyases by three thermophilic fungi,i.eThermomyceslanuginosus, Talaromycesluteus and Rhizomucorpusillusunder different cultural conditions was studied. Although all the three fungi were able to produce pecticlyases (exo-pectinlyases (exo-PL), endo-pectic acid lyase (endo-PAL), exo-pectinlyase (exo-PL) and pectic acid layse (endo-PAL) the degree of production varied with the fungus and prevailing environmental conditions. Temperature of 45ºCand pH 6.0-7.0 were optimum for production of different pecticlyases by the fungi understudy. The preference of carbon and nitrogen sources varied both with the fungus and enzyme concerned. A positive correlation could be observed between mycelial growth and pecticlyases production. The production of pecticlyases byall the three fungi under investigation proved to be adaptive.

ABSTRACT

Altogether twenty one species comprising eighteen genera of endophytic fungi were recovered from surface sterilized leaf lamina, leaf mid -rib, stem, petiole and inner bark samples collected from Catharanthusroseusfrom four different locations of the Maharashtra. A total of 395 endophytic isolates were obtained from 1200 plant segments of C. roseus.Mitosporic fungi were found to be dominant (74%), followed by ascomycetes (17%) and agonomycetes (9%). The overall colonization and isolation rates of endophytic fungi were significantly higher (χ 2 test, g= 4, P<0.001) in stem when compared to other aerial parts. The overall colonization of endophytes recovered in monsoon season were significantly (χ 2 test, g = 2, P<0.001) higher (33%) followed by summer (16.25%) and winter (15.25%). Similarly, the isolation rate was also found significantly higher during monsoon (0.59) than the summer (0.2) and winter (0.18).

ABSTRACT

Alkaline protease isolated from marine fungus Engyodontium album BTMFS10 was evaluated for its potential use as an additive in detergent formulations in detergent industry. Commercial detergent compatibility studies conducted with the E. album protease indicated that in all the detergents tested, the enzyme retained more than 90% of activity even after 3 h of incubation. Comparison of stability of E. album protease and other proteases in the presence of commercial detergent (Surf Excel Automatic) at 60 °C showed that E. album protease was significantly more active than the commercially available proteases tested. Additionally, wash performance research supported the efficiency of E. album protease in removing blood stains from clothing.  Esterase activity of the protease indicated by the cleavage of p-nitrophenyl derivatives of small chain fatty acids and was confirmed by activity staining. This fungal protease facilitated stripping of the gelatin layer of the used X-ray film towards recovery of silver. The results of the studies testified the potential of marine fungal protease for application as an addition in detergent compositions, and also in silver recovery from used X-ray films. 

Key words: Engyodontium album, Alkaline protease, Detergent additive, Silver recovery

ABSTRACT 

Farms, food processing facilities, numerous factories, and other industries are producing alarming amounts of agro-industrial waste, which necessitates immediate action to prevent the negative environmental effects of its disposal and incineration. The waste, which primarily comprises cellulose, hemicellulose, and lignin, collectively known as lignocellulosics, holds significant untapped potential for various agro-based applications and industrial processes. In particular, mushrooms use this waste as a substrate. By producing lignocellulolytic enzymes, mushrooms break down lignocellulosic substrates and utilize them in the formation of their fruiting bodies. Consequently, mushroom farming has emerged as a leading biotechnology strategy. It addresses and benefits from agro-industrial byproducts in environmentally friendly, and sustainable alternative approach. It biotransforms low-value agricultural byproducts into protein-rich nutritious foods that significantly enhances human health and contributes to the development of rural economies. Moreover, it serves as a bioremediation strategy that is less intrusive than other methods of environmental restoration. Recently, the substratum of mushrooms has been acknowledged as an invaluable source of biofuels and a plethora of enzymes that have significant vital functions in various industrial operations and are of substantial commercial value. This article offers a summary of recent scientific understanding regarding the mushroom substratum as a resource of industrially significant enzymes and biofuel.

Keywords: Agro-industrial waste; Biofuels; Enzymes; Mushroom mycelium; Spent mushroom substrate; Sustainable industrial applications.

ABSTRACT

Mushroom mycoflora belong to kingdom Mycota (Fungi), which harbors the most diverse group of organisms after insects on earth. Since the beginning of time, macrofungi have drawn the attention of humans due to their peculiar and startling characteristics, such as their varied color, form, and size as well as the existence of gills and pores. Macrofungi also shows great diversity in their inhabiting behaviors encompassing saprobic and parasitic. In the present study, diversity of wood inhabiting macrofungi was surveyed in study area (Ayodhya). Findings exposed a total number of 30 macrofungal species belonging to 14 families. Morphological, microscopic, and macroscopic characters were recorded. Wood inhabiting macrofungi play important role in the biogeochemical cycle of ecosystems. It helps degrade the ligno-cellulosic waste materials and release nutrient back into the ecosystem. In addition to softening wood tissues, the degradation process of wood-growing macrofungi demonstrates collaboration with other micro-organisms.

Abstract

Pectins play a vital role in maintaining the structure and firmness of plant tissues, providing resilience to cell walls and protecting plants from drought and wilting. Fungi possess a diverse group of extracellular pectinolytic enzymes, known as pectinases, which serve as valuable tools for infecting their host plants or drawing energy by degrading plant materials. Pectinases specifically target and break down pectin and pectic substances into monomers with diverse modes of action. In food processing, winemaking, paper, tea, coffee and textile industries, pectinases are widely recognized as the commonly used enzymes. They are employed in developing new products, enhancing production of the existing products, physical, chemical and sensory properties and increasing overall yield. This review aims at targeting the biochemical characteristics of fungal pectinases, with specific focus on their relevance in different industries. Additionally, it provides a comprehensive overview of the applications of fungal pectinases in various industrial processes.

ABSTRACT

In the present study, 126-day-long commercial-scale demonstration of a circular-economical bio-refinery, its sequential operational stages, employing 96 kg of a substrate mixture comprising urban vegetative waste and e-commerce packaging waste, resulted in yields of: 36 kg of mushrooms; 124,800 IU of exoglucanase; 1.2 x 1013 seed bio-priming agents; 1.08 L of bio-ethanol; 6.76 kg of bio-compost/bio-fertilizer. The first stage of oyster mushroom cultivation resulted in degradations of 73.8% lignin and 88.2% hemicellulose. Remnant biomass from the mushroom cultivation phase was subjected to solid-state fermentation (SSF) employing Trichoderma koningii Oudemans Tk-7 for the production of in-house cellulases. Post SSF, the harvested spores of T. koningii, when used as a seed bio-priming agent, resulted in a 26% average increase in the percentages of germination. Remnant biomass from SSF, after an in-house cellulase-based saccharification and fermentation, resulted in a bio-ethanol yield of 0.43 g/g of glucose. The unsaccharified biomass fraction, when subjected to cow dung-based aerobic windrow composting, resulted in a bio-compost, which exhibited a 242.5% increase in seed germination indices. Significant variables related to bio-process and substrate utilization have been analysed. With a ~70% process-related profit margin, the proposed approach could prove to be a promising agripreneurial proposition.

ABSTRACT

Various carbon sources were evaluated for production of inulinase by Fusarium oxysporum RS-115. Highest inulinase activity was observed with garlic extract (15.24 nkat/ml) as carbon source. The enzyme activity was 2.8 folds higher than that observed in media containing pure chicory inulin (5.39 nkat/ml). The Fungus showed good growth on a simple medium containing garlic extract (20% w/v) and yeast extract (2%w/v) as carbon and nitrogen source respectively, in 120 h at 30°C and 150 rpm. Among various protein sources tested, yeast extract was found to be the best source followed by peptone (12.15 nkat/ml) and beef extract (9.84 nkat/ml). The enzyme was optimally active at pH (5.0) and 50°C. All metal salts except MnSO4, MgSO4 and FeCl3 were not well tolerated and did adversely affect inulinase activity. Inulinase activity was found reduced significantly in presence of EDTA and PMSF whereas the activity of inulinase was inhibited by pCMB. TLC and HPLC analysis of end products revealed that inulinase hydrolyzed inulin exclusively into fructose and fructooligosacharides. Results suggest that the garlic induced endoinulinase synthesis in F. oxysporum RS-115 and can be utilized as a potential substrate for inulinase production.

Key words: Inulinase, Allium sativum, fructoologosaccharides, Fusarium oxysporum.

Abstract

Plants encounter a variety of difficulties when they are growing, many of which are exacerbated by increasing anthropogenic activities. Among such challenges, heavy metal accumulation in plants has raised serious concerns for the ecosystem and human health. Phytoremediation has emerged as a viable strategy to restore soil fertility without requiring expensive processes in order to solve the issue of heavy metal toxicity in an environmentally sustainable manner. However, several problems that lead to low plant growth rates due to metal toxicity in polluted soil limit the effectiveness of this technique. Arbuscular mycorrhizal fungi (AMF) effectively reduce heavy metal phytotoxicity and play a pivotal role in phytoremediation by augmenting plants’ tolerance. AMF contributes to the successful remediation of contaminated sites, acts as a biofertilizer, promotes plant growth, enhances yield, and improves overall plant quality. This review summarized the potential of AMF in promoting plant development and addressing various challenges faced by plants exposed to heavy metals. It discussed the different roles that AMFs play and the mechanisms through which they contribute to phytoremediation. By understanding the beneficial effects of AMF, we can harness their potential to mitigate the detrimental impacts of anthropogenic activities and ensure the sustainable management of ecosystems.

Abstract

Fusarium wilt is serious disease of muskmelon throughout globe. Fifty accessions of muskmelon and its relatives (Fom differentials, snapmelon and wild melon) were used for hybrid making in half diallel manner. Fifty accessions were screened at expanded cotyledonary stage after inoculation with local Fom isolate under artificial conditions. Based on disease severity, eight accessions were found highly resistant (0.00-21.67%) and three moderately resistant (28.33-36.67%).The Fom resistant differentials; Hemed (AUDPC 850; severity 91.67%) and F-65 (AUDPC 983.33; severity 88.33%) showed susceptible reaction, which signifies the presence of new Fom pathogenic race. Further, eight highly resistant and two susceptible genotypes were crossed to generate 45 hybrids. These hybrids were screened under wilt sick plot for two consecutive years for fusarium wilt disease incidence and other important yield traits. Out of 45 hybrids, KP4HM-15 × MM-202, KP4HM-15 × Kajri Sel. 1, MM-314 × KP4HM-15, and Kajri Sel. 1 × MM-202 were best performing resistant hybrids for yield and quality traits with least incidence of fusarium wilt disease. Based on the results, we concluded that, novel putative resistant genes prevail in Indian germplasm which can further be mapped for the identification of linked markers to strengthen the hybrid development program against newly evolving pathogenic races in muskmelon and cantaloupe.

ABSTRACT

Mushrooms are edible macrofungi grown in many countries using various agricultural wastes.  Mushrooms transform lignocellulosic waste and residues into valuable bioactive compound which are very important in the food and pharma industry.  The purpose of this study was to grow Calocybe indica on 5 different substrates (Type A, Type B, Type C, Type D, and Type E) prepared from agro-waste such as rice bran, wheat bran, cow dung, rice straw, and leftover orange residue after essential oil extraction. Type-C substrate showed the highest biological efficiency, giving an optimal mushroom yield of 16.049% w/w and also exhibited the highest nutritional value as follows; the highest phenol content was observed in the Type-D category and the lowest in Type-C category, where mushroom showed 2.11 GAE/100g phenol content. The Type-B category mushrooms show the highest carbohydrates, energy, and ah contents compared to other types category mushrooms. The Type-E category mushroom shows highest protein and fibre content. The Type-D category mushroom contains highest Phenol and moisture content. The Type-C category mushroom contain normal and low nutritional values compared to another category mushroom. Therefore, black soil in a trace amount along with orange residue would enhance the biological efficiency and nutritional profile of Calocybe indica.

ABSTRACT

The present study investigated the diversity of arbuscular mycorrhizal fungi (AMF) associated with four mangrove plant species viz., Avicennia marina, A. officinalis, Rhizophora apiculata and R. mucronata in two locations of Cuddalore and Mayiladuthurai districts in Tamil Nadu, India. Soil properties were analysed to determine their potential effects on the distribution of AM fungi. The present study revealed that all the mangroves had AM fungal association with varying amount of root colonization (55-86%) and soil spore density (176 to 350 spores/100g soil). Among them, R. mucronata was recorded with the maximum spore density (350 spores/100 g soil) while A. officinalis had the minimum spore density (176 spores/100 g soil). Physico chemical analyses showed the soil had slightly acidic pH (6.2-6.5), low level of phosphorus (P) (14.23-17.25 kg/acre), and high level of nitrogen (N) (51.2-54.5 kg/acre).  Soil P and salinity appeared to be the important factors influencing AM fungal association in mangrove plants. The AM fungal spores of four different genera viz., Acaulospora, Gigaspora, Glomus, and Scutellospora were recorded. The AM fungi were found to be an important component on the landward fringe of mangrove habitats.

ABSTRACT

In this study, Talaromyces qii belonging to the section Talaromyces is reported as a new record from India based on the morphology and phylogenetic analyses of four gene datasets viz. ITS, BenA, CaM, and rpb2. This is the second report of this rare Talaromyces species from across the world. Phylogenetically, the Indian strain T. qii (NFCCI 5151) formed a sister lineage to the type species T. qii (AS3 15414) due to the sequencing error in the type. The quality assessment of the four gene sequences derived from all type strains of section Talaromyces in this study evaded the proposal of a redundant novelty in this section, aligning the Indian strain NFCCI 5151 along with T. qii (AS3 15414). Morphology of type strain T. qii (AS3 15414) and T. qii (NFCCI 5151) are mostly identical, viz. elongated, biverticillate-symmetrical conidiophores, acerose phialides, and ellipsoidal or sub-globose conidia with echinulate ornamentation. However, the Indian strain has longer conidiophores and a larger conidia size than type strain T. qii and T. thailandensis. This study resolved the phylogeny of a new record of Talaromyces qii in the section Talaromyces from India through the most modern taxonomic approaches.

ABSTRACT

Marine microorganisms are promising source of enzymes with industrial applications due to their immense genetic and biochemical diversity. Availability of novel enzymes, advancements in enzymology and enzyme technology have significantly contributed to the industrial application of enzymes and the rapid expansion of the enzyme market. In this context marine fungal enzymes assume greater attention recently owing to the great demand for novel and efficient biocatalysts for industrial applications and other services. This situation has warranted exploration of marine fungal biodiversity for new enzymes. The present review focus on bioprospecting of marine fungal enzymes produced by lesser studied fungi, identification of research gaps, challenges in pursuing research in harnessing the potentials of marine fungi, and the scope for future prospects. Role of fungal enzymes in biogeochemical processes in marine environments, bioremediation, and plastic degradation is discussed indicating marine fungi as source of industrial enzymes. Scope for exploring marine fungal diversity and potentials of extremozymes, cold adaptive enzymes and halophilic fungal enzymes, besides the need for bioprocess development are discussed. Moreover, the challenges lying ahead in pursuing research on marine fungi are also discussed to draw the attention of mycologists and biotechnologists to appropriately harness the marine fungi.

ABSTRACT

A nutrient enriched bio-formulation(s) was prepared by inoculating the combination of bio-inoculants viz., Trichoderma sp., Pseudomonas fluorescens and Azotobacter chroococcum in vermicompost supplemented with minimal inorganic fertilizers i.e., Diammonium phosphate and Muriate of potash, which is compatible with bio-inoculants. Twenty four Trichoderma isolates were isolated from different locations of Dhamtari, Rajnandgaon, and Kabirdham District of Chhattisgarh. All the 24 Trichoderma isolates were evaluated for compatibility with P. fluorescens and A. chroococcum. Three Trichoderma isolates were found compatible with both the bacterial bio-inoculants. Trichoderma isolates TRT2, TRT-9, and TRT-12 found potentially able to produce IAA, siderophore, HCN, cellulase, chitinase, and phosphatase. Similarly, P. fluorescens and A. chroococcum individually having potential to produce IAA, siderophore, HCN, cellulase, chitinase, and phosphatase. Trichoderma isolate TRT-2 did not produce HCN and A. chroococcum did not produce cellulase enzymes. Trichoderma isolates i.e. TRT-2, TRT-9, and TRT-12, P. fluorescens and A. chroococcum individually were further evaluated for sensitivity with inorganic fertilizers i.e., DAP, MoP, SSP, urea, and complex fertilizer 28:28:00. TRT-2, TRT-9, and TRT-12 were inhibited by urea and complex fertilizer (28:28:00) at all concentrations. However, SSP could not inhibit the growth at any concentration, whereas inhibition percentages in DAP were ranged, 0.00-42.10%, 0.0-0.20%, and 0.37-19.11% for TRT-2, TRT-9, and TRT-12, respectively. Successive increases in concentration up to 5% of fertilizer could not affect the growth of isolate TRT-9 that leads to resistance. Based on the above mentioned findings, three formulations (1) Vermicompost enriched with three bio-inoculants i.e. Trichoderma isolates, P. fluorescens, and A. chroococcum, (2) DAP (5% w/w) and MoP (2% w/w) supplemented vermicompost enriched with three bio-inoculants i.e. Trichoderma isolates, P. fluorescens and A. chroococcum, and (3) DAP (10% w/w) and MoP (3% w/w) supplemented vermicompost enriched with three bio-inoculants i.e. Trichoderma isolates, P. fluorescens, and A. chroococcum, were constituted and evaluated.

ABSTRACT

An investigation was carried out for three mangrove plant species from two coastal regions - Parangipettai and Pazhayar - of Cuddalore and Mailaduthurai districts, respectively, Tamil Nadu, India to determine their symbiotic association potential with arbuscular mycorrhizal (AM) fungi. All mangrove plants developed AM fungal colonization in their root tissues with a mean range of 85% - 95%. All the soil sediment samples had AM fungal spores with a density range from 196 - 1403 spores/100g air-dried soil sediment. Variations in AM fungal root colonization and soil spore densities were found statistically significant. Maximum percent root colonization and soil spore population of AM fungi were recorded in samples of Rhizophora mucronata in both the study locations. Frequency distribution of AM fungi was also determined, and it was found that the rhizosphere samples of three mangrove species had maximum fungal population of Rhizophora mucronata, which was followed by that of R. apiculata in both the study locations. Significance of the findings is discussed in detail.

ABSTRACT

Trichoderma asperellam is a fungal species that is frequently utilized in the biological control of plant pathogenic fungi. The creation of analytical enzymes enhances its ability to control biological infections. It has been highlighted that physical traits alone are insufficient for identifying these fungal species. As a result, the study's goal was to use molecular markers to identify Trichoderma species and assess their antagonistic effectiveness against plant pathogens. T. asperellam have antagonistic and physiologically controlled activity, which inhibited the pathogenic fungus to the greatest extent possible in a dual culture approach. T. asperellam had the highest inhibition (62.7%), followed by T. harzianum (56.0%), T. koeningii (56.0%), Aspergillus niger (52.5%), Aspergillus sulphureus (48.5%), Penicillium sp. (48.41%), and Aspergillus flavus (47.3%).
