What are Cellulolytic microorganisms?

Cellulolytic microorganisms are mostly utilizing carbohydrates for their energy but are unable to use proteins or lipids as energy source for their growth (Lynd, Weimer, Van Zyl, & Pretorius, 2002).

What is the function of cellulolytic bacteria?

Cellulolytic bacteria and fungi that secrete free enzymes depend on the hydrolysis of lignocellulose into usable sugars by enzymes with specific substrate specificities. In general, there is believed to be cooperative or synergistic action between at least three classes of free enzymes.

What are cellulolytic enzymes?

Cellulolytic enzymes break down cellulose and hemicellulose into glucose and xylose, which are used in the bioethanol production [45,46].

Which bacteria can break down cellulose?

One particularly important bacterial genus that takes part in the degradation of cellulose is gram positive Ruminococcus (Figure 1). Ruminococcus bacteria break down the plant fiber into the monosaccharide glucose, which can then be further broken down through glycolysis.

Where can cellulase be found?

Enzymes in the Beverage Industry Cellulases are produced by bacteria and fungi (Sharma et al., 2017). Microbial cellulases are produced from fungi especially Aspergillus niger, Aspergillus nidulans, and Aspergillus oryzae (Sukumaran et al., 2005).

What is CMC Agar?

CMC agar allows us to identify isolates with cellulase activity on soluble cellulose such as CMC thus representing mainly endoglucanase and beta- glucosidase activities.

What is cellulose used for?

Cellulose is the main component of paper, cardboard, and textiles made of cotton, flax, or other plant fibers. It is also used for the production of fibers, films, and cellulose derivatives.

What is the difference between cellulose and cellulase?

Cellulose is a carbohydrate (polysaccharide) and cellulase is a protein. Cellulase is an enzyme family which catalyses the breakdown of cellulose. Cellulose is mainly found in plant cell walls, and cellulase enzyme is mainly found in cellulose digesting bacteria, fungi and protozoa.

What is the role of cellulase?

Cellulase catalyzes the decomposition of cellulose polysaccharide by simply breaking down β-1,4-glycosidic bonds. Three major types of enzymes are generally involved in hydrolyzing cellulose microfibrils in the plant cell wall: endoglucanase, exoglucanase, and β-glucosidase.

What enzyme digests cellulose?

Cellulase
Which enzyme is responsible for breakdown cellulose? Cellulase is responsible for breaking down cellulose. It breaks down cellulose into monosaccharides such as beta-glucose or short polysaccharides and oligosaccharides.

What organisms are involved in cellulose decomposition?

Under the acidic condition, fungi are the primary group of organisms involved in cellulose decomposition, whereas bacteria and actinomycetes act as dominant cellulose decomposers in neutral to alkaline conditions.

Do plants produce cellulase?

All plant cellulases belong to family 9, which endohydrolyzes cellulose, but are not strong enough to cause the bulk degradation of cellulose microfibrils in a plant body. It is hypothesized that cellulase participates primarily in repairing or arranging cellulose microfibrils during cellulose biosynthesis in plants.
