“…Since fungi possess a proficient hydrolytic system that is capable to convert lignocellulosic material to essential metabolites in the form of mushrooms. Usually, fungi (micro and macrofungi) secrete enzymes, including cellulases (cellobiohydrolases, endoglucanases), hemicellulases (xylanases), and β-glycosidases [21,22]. The recent developments in our understanding of the genetics, physiology, and biochemistry of fungi, has led to the exploitation of fungi for the preparation of different agriculture and industrial products of economic importance [4], therefore the agric residue which is rich in lignocellulose consists of lignin, hemicellulose, and cellulose [11,23] can potentially be converted into different value-added products as depicted in (Figure 1) including biofuels, chemicals, animal feed, textile and laundry, pulp and paper.…”

Production of ethanol and other alternative fuels from lignocellulosic biomass can reduce urban air pollution, decrease the release of carbon dioxide into the atmosphere, and provide new markets for agricultural wastes [21].…”

Fungi being achlorophyllous depends on other living organisms for their food either being parasite or saprophyte. Saprophytic fungi are good biodegraders. Through their enzymatic batteries, they can degrade any organic substances. Most of the time during the processes of degradation, macrofungi (mushrooms) are occurred as per the climatic conditions prevailing in the particular locations. Micro and macrofungi are considered a good source of human nutrition and medicine since time immemorial. Some of the fungi which are commonly known as mycorrhizae facilitate nutrients to more than 90% of green plants. Fungi play a basic role in plant physiology and help in the biosynthesis of different plant hormones that provides the flexibility of plant to withstand adverse environmental stress, the whole fungi are more friend than foe.

The ceaseless quest for economical cellulase, an enzyme that hydrolyzes cellulose, has led to exploring diverse environments, such as insect guts. In this study, we report the optimization of cellulase production and isolation, purification, and characterization of cellulose-degrading enzymes from Aspergillus awamori AFE1. Aspergillus awamori AFE1 was screened for its cellulase-degrading ability, and molecular and phylogenetic analyses of the isolate were performed. Two activity peaks were observed during ion exchange chromatography. A final purification fold of 0.86 and 1.86 with a recovery of 0.18% and 0.44% were achieved for cellulase A and B, respectively; molecular weight of 48.5 KDa and 36.5 KDa for A and B, respectively. The optimum pH of 5.0 was observed for both purified cellulases, and both were stable at an acidic pH of 4.0. An optimum temperature of 60 oC for CA and dual optimum temperatures of 60 and 70 oC were obtained for CB, while both were stable at 30 oC with 63 and 61% residual activity after 2 h, respectively. Fe2+ stimulated both cellulase activity, whereas Zn2+, Cu2+, Mn2+, K+, and Na+ inhibited cellulase activity. Similarly, urea, ascorbic acid, and EDTA inhibited the enzyme. The enzymes were stable in the presence of some organic solvents. The Km and Vmax values were found to be 3.86 mM and 0.3159 mg/ml/min, 4.12 mM, and 0.223 mg/ml/min for the enzyme. The remarkable and unique physicochemical properties of cellulases from Aspergillus awamori AFE1 could be exploited for industrial and biotechnological applications.
