How is cellulase enzyme produced?
Cellulases are the enzymes that hydrolyze β -1,4 link- ages in cellulose chains. They are produced by fungi, bacteria, protozoans, plants, and animals. The catalytic modules of cellulases have been classified into numer- ous families based on their amino acid sequences and crystal structures ( Henrissat, 1991 ).

Where is cellulase enzyme produced?
1 Molecular structure of cellulase. It is produced by fungi, bacteria, actinomycetes, protozoans, plants, and animals. According to Carbohydrate-Active Enzymes database, there is information of the glycoside hydrolase families.
What is cellulase production?
Cellulase is produced by a large number of microorganisms. They are either cell bound or extracellular. Although a large number of microorganisms can degrade cellulose, only a few of them produce significant quantities of free enzymes capable of completely hydrolysing crystalline cellulose [15.
What is the main industrial source of cellulase enzymes?
Trichoderma reesei is the major fungus for industrial cellulase production. Its genome encodes 10 cellulases and 16 hemi-cellulases (Martinez et al., 2008). It produces two exoglucanases (CBH I and CBH II), about eight endoglucanases (EGI–EGVIII), and seven β-glucosidases (BG I–BG VII).
How is cellulose obtained?
Cellulose for industrial use is mainly obtained from wood pulp and cotton. Some animals, particularly ruminants and termites, can digest cellulose with the help of symbiotic micro-organisms that live in their guts, such as Trichonympha.
Why is the enzyme cellulase?
UPLOAD PHOTO AND GET THE ANSWER NOW! Solution : Plant cells have cell wall made up of cellulose where as animal cells lack cell wall and do not contain cellulase. Therefore, the enzyme cellulase is needed for isolating genetic material for plant cells only….

What is cellulase and its function?
Cellobiose is a disaccharide with the formula (C6H7(OH)4O)2O. It is classified as a reducing sugar. In terms of its chemical structure, it is derived from the condensation of a pair of β-glucose molecules forging a β(1→4) bond. It can be hydrolyzed to glucose enzymatically or with acid.
How is cellulase produced industrially?
Cellulase fermentation was conducted with high-titer enzyme-producing strain CDU-11 under semi-batch conditions in a 4-L fermentor, using inexpensive carbon and nitrogen sources and the pH-shift system. This resulted in the production of CMCase activity exceeding 600 U/ml and (3-glucosidase activity exceeding 30 U/ml.
Which enzymes are involved in breaking cellulose?
Cellulase enzymes degrade cellulose to glucose. Cellulase includes three enzymes such as β-1,4-endoglucanase, cellobiohydrolase, and β-glucosidase (Jecu, 2000). Cellulases are produced by bacteria and fungi (Sharma et al., 2017).
What is the main source of cellulose?
wood
Although the primary occurrence of cellulose is the existing material in forests with wood as the most important source, cellulose-containing materials include agricultural residues, water plants, grasses, and other plant substances.
