Fungi are prominent sources of pharmaceuticals and are utilised in several industrial fermentative processes, such as the production of enzymes, vitamins, pigments, lipids, glycolipids, polysaccharides and polyhydric alcohols.

For the duration of the past 50 years, many key advancements in medicine came from lower organisms such as molds, yeasts and the other diver’s fungi. Fungi are very helpful in producing high value products like mycoproteins and acts as plant growth promoters and disease suppressor. Fungal secondary metabolites are critical to our health and nutrition and have tremendous economic impact. In addition to this, fungi are incredibly useful in carrying out biotransformation processes. Recombinant DNA technologies, which consists of yeasts and other fungi as hosts, has markedly increased market place for microbial enzymes.

Nowadays, fungal biotechnology is a key participant in the global business due to its mind blowing prospective.

A) Designing of vectors

Yeast vectors are employed in genetic engineering. E.g., shuttle vectors are used for expression

of desirable gene in each prokaryotic and eukaryotic systems.

YAC, YRP, YIP, YEP are some other yeast vectors.

B) Fungi as a food

Fungi are utilised as high cost food due to the fact of its high protein and low calorific value.

Europe, America, Australia and Japan are quite playing industries in mushroom cultivation.

Some of the edible fungi (Mushrooms)are given as below.

1) Agaricus compestris

two) Volvariella (paddy straw mushroom)

3) Morchella (Temperate zone mushroom)

four) Pleurotus sp. (oyster mushroom)

5) Agaricus bisporus (white button mushroom)

C) Fungi as a rich source of SCP

Fungi are utilized as the rich sources of Single Cell Proteins. Some of the fungi for SCP are given as

1) Yeast (S. cerevisae)

2) Aspergillus niger

3) Penicillium chrysogenum

4) Fusarium avenacum

five) Neurospora sitoplila

D) Isolation of fungal metabolites of pharmaceutical importance

Aspergillus nidulans and other fungi are utilized for isolation of secondary metabolites. The secondary metabolites are utilized as drug. Ergot alkaloids (Ergometrin and Ergotoin) and Lovastatin, a common cholesterol-lowering drug are the secondary metabolites.

Fungal metabolites have antitumour, antiviral, antibacterial and immunosuppressants activities.

E) Fungal pathogens as nibblers

Fungal pathogens are use as root nibblers to generate several root fibers that boost the maximum uptake of nutrients and water for a lot more yield.Trichoderma viridae and fusarium has shown increased number of root fibres in Tomato &amp Maize plants.

F) Fungi in improving the high quality of produce

It is evidence that some fungal illnesses can boost the nutritional good quality of food &amp feed. E.g. smutted corn and rust infected wheat grains have a lot more carbohydrate and phosphorus contents as compare to healthy plants.

G) Fungi as biofertilizes

Vesicular arbuscular mycorrhizae are the mutualistic symbiosis among the roots of higher plants and particular fungi. The mycorrhizae help in the phosphate nutrition of plants and safeguard the roots by forming the mantle.

H) Fungi as “Microbial weed killer “(Bioherbicides)

Fungi are recognized for its really distinct&amp effective action and have low residual effects in comparison with synthetic pesticides. Here are given some fungi as bioherbicides.

Fungi are employed as bioherbicides,some examples with their targets are given in brackets.These are Septagloeum gillis (Mistletoes)

Wallrothiella arecuthobii (Mistletoes)

Colletotrichum gloeosporiordes(Mistletoes)

Phyllosticta (Glycosmis)

Leptosphaerulina trifolia(Passiflora)

Puccinia chondrillina(Rush weed)

Cercospora ageratinae(Pamakani weed)

I) Cellulose degradation by fungi

Heap of agricultural residues, forest residues deposited ample of celluloses in the soil. Only fungal cellulases are involved in degradation of deposited cellulose. Fusarium, Trichoderma, Penicillium derived cellulases are involved in degradation of celluloses. Degradation of these leads maximum bioenergy production. Some of the other fungal enzymes are ? gluconase and ? glucosidase (cellobiase).

J) Bioconversion of lignin

White Rot fungi such as Coriolus versicolor, Polyporus ance and Brown Rot fungi like Poria monticola, Lenzitis trabea are utilised in depolymerization and degradation of lignin to low molecular weight Petroleum goods. These fungi are also employed in softening of wood in paper making industries.

K) Entamopathogenic fungi

This group of fungi secretes the toxin, which possesses the entemocidalproperties. The role of entamopathogenic fungi, its items and effects are given as below.

L) Industrial Applications of fungi

Fungi are widely utilized in fermentative industries for the production of ethanol, organic acids, antibiotics and enzymes like fungal cellulases, ? gluconase and ? glycosidase. Particular fungi like P.notatum, P.crysogenum and Cenococcum Sp.are utilized in antibiotics production where as S.cerevisae and Monilia Sp. are employed in ethanol production. Fungi are also beneficial in ripening of cheese and processing of other merchandise.

M) Biodegradation of pesticides/ Toxic chemicals and petroleum

White Rot fungi have the potential role in degradation of toxic pesticides like DDT, PCB and Lindane. In addition to this, it can degrade certain toxic chemicals like dioxin, benzopyrene, cyanides, azides, CCl4 and Pentachlorophenol (PCP). Aspergillus, Penicillium, Paecilomyces and Fusarium has located to be involved in petroleum degradation at 30 0C in contaminated soil.

N) Biodegradation of Azo dye and Hydrocarbons

Peroxidase enzyme of Penicillium crysosporium &amp Streptomyces sps. have possible biodegradable activities that degrade Amaranth dye, Orange G, heterocyclic dyes like, Azure B and Lip dye. The filamentous fungi are also getting role in degradation of toxic hydrocarbons.

O) Fungi in Hazardous waste remediation

Fungi aid in remediation of explosive contaminated soil by its lignin degrading Enzymes

TNT, RDX, HMX are some of the possible explosives that contaminates soil and water. Other degradable nitro explosives by Pleurotus ostreatus are as follows:

Nitrobenzene

4-Nitrophenol

4-Nitroaniline

1-Methoxy 4 nitrobenzene

two-Methoxy 4-nitro phenol

1, 2, di Methoxy 4 nitrobenzene

P) Biomineralization of Heavy Metals

The fungi have eminent role in the removal &amp recovery of heavy metals from wastewater and industrial effluents. Hg, Cu, Ni, Pb, Cd are extracted at pH 2-five by myceliar beads of Penicillium.

Conclusion

Fungi are the organisms that have prospective role in degradation of explosives. It is observed by repeated laboratory studies involving pure cultures of white rot fungi. It also assists in degradation of hydrocarbons in the environment. Fungi attract considerable attention due to their feasible involvement in the diverse applications. So far, significant numbers of enzymes have been purified from fungal cultures and characterized in terms of their biochemical and catalytic properties. It possesses antimicrobial activities and is used in biomineralization, as a food for its high protein contents and as a biofertilizers.
