“…Glucose units one of the smaller sugar components produce by cellulases are a group of hydrolytic enzymes capable of hydrolysing cellulose. The nature's biodegradation processes product by cellulolytic enzymes where plant lignocellulosic materials are efficiently degraded by cellulolytic fungi [24]. This result agreed with the study [25] regardingan Training to isolate the fungi from the undiscovered soils of (Western Ghats) and screen them for the production hydrolytic enzymes as cellulase and CMCase.…”

134 samples of plants and animals wastes were taken from three different regions outside Baghdad and three different regions in Baghdad. 24 cellulolytic isolates fungi AO, C1, TH1, AN1, R1, TV, PG, AF, B1, L1, AP, TH, AP1, AN3, AO2, A, A1, C, F, AO1, C2, F1, CL and AP2 independent were chosen out of 48 selected fungi. The best optimal conditions for growth were 30ºC and pH 7. The isolates were identified and screened according to the colony diameter, biomass and density of spores in addition of capability to produce the hydrolytic enzymes for cellulose.

“…Based on morphological and cultural characteristics, RPW 1/3 and RPW 1/10, RPW 1/6 and RPW 1/9, and RZWM 3/1 were identified as Aspergillus flavus, Aspergillus terreus and Aspergillus niger, respectively. Many Species of Aspergilli produces cellulases and exhibits strong hydrolytic activity towards cellulose (Ogbonna et al 2015). Some species of Aspergilli like A. flavus (Saritha and Maruthi 2010), A. niger (Chinedu et al 2008) and A. terreus (Jahromi et al 2011) were found effective in the biodegradation of different lignocellulosic materials by producing oxidative and hydrolytic enzymes.…”

Purpose In North West-Indo Gangetic Plains (NW-IGP) of India in situ burning of crop residues is practiced by majority of farmers' which deteriorates soil and environmental quality. Fungi have the potential for lignocellulose degradation and can be used for the in situ decomposition of crop residues. Lignocellulose degrading fungal spp. were isolated and evaluated for the activity of lignocellulolytic enzymes. Method The lignocellulose degrading fungi were isolated by appearance of zone on carboxy methyl cellulose (CMC) agar media and tannic acid (TA) media. Carboxy methyl cellulase, filter paperase, cellobiase, xylanase and laccase activity were estimated in submerged, as well as solid state fermentation using a mixture of rice and wheat straw in the ratio of 4:1. rice-wheat straw as substrate. The residue left after solid state fermentation was evaluated for carbon/nitrogen ratio, dry mass loss, and loss of cellulose, hemicellulose and lignin. Selected potential isolates were further tested in pot experiment for their effect on wheat plants. The interaction among isolates was also studied. Result After primary screening, 19 out of a total of 72 fungal isolates were selected based on their enzymatic activity profile and potential to degrade lignocellulosic residues in submerged fermentation. Out of these 19 isolates, 11 were further selected based on their enzymatic secretions in solid state fermentation. All the 11 strains were identified morphologically. Four fungal isolates (RPW 1/3, RPW 1/6, RPWM 2/2 and RZWM 3/2) showed higher enzymatic activities and more loss of dry mass and cell wall constituents over the other isolates. These isolates were identified by ITS region sequencing as Aspergillus flavus, Aspergillus terreus, Penicillium pinophilum and Alternaria alternata. Conclusion This study revealed that fungal isolates may be used for managing crop residues in conservation agriculture based rice-wheat system of NW-IGP to eliminate ill effects of residue burning.
