Cellulase (EC 3.2.1.4; systematic name 4-β-D-glucan 4-glucanohydrolase) is any of several enzymes produced chiefly by fungi, bacteria, and protozoans that catalyze cellulolysis, the decomposition of cellulose and of some related polysaccharides: Endohydrolysis of (1→4)-β-D-glucosidic linkages in cellulose, lichenin and cereal β-D-glucan

Cellulose is essentially an important and main structural component of the cell wall of green plants making it most abundant polymer on earth. Cellulose is composed of long chain of glucose units linked by β-1,4-glycosidic bonds, cellulases hydrolyze these β-1,4 linkages in cellulose.

Cellulase hydrolyzes the biomass into simple sugars, either pentose or hexoses, which are then fermented to fuel or bioethanol. Cellulases are mainly involved in the bioconversion of renewable lignocellulosic biomass.

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.

Apr 11, 2016 · Cellulose, an eminent representative of naturally available nanostructure renewable matter, is a component of all plants, algae, and tunics of marine creatures. It has been evaluated that in terrestrial ecosystems, half amount of the fixed carbon is stored in the form of cellulose per annum.

Microbial cellulases have become the focal biocatalysts due to their complex nature and wide spread industrial applications. Cellulases are composed of independently folding, structurally and functionally discrete units called domains or modules, making cellulases module [1].

Cellulase plays an important role in modern industry and holds great potential in biofuel production. Many different types of organisms produce cellulase, which go through secretory pathways to reach the extracellular space, where enzymatic reactions take place.

Jan 14, 1999 · Cellulose is the renewable and ample biopolymer generated on earth yearly. It is a crystalline matrix of linear β-1,4- d glucan chains composed of long unbranched glucose polymers. In nature these organic matters is converted to simple compounds by …

Jun 19, 2018 · Cellulase is an enzyme that breaks down the cellulose plant fibers we eat into beta-glucose and short-chain polysaccharides. Almost all species of bacteria, fungi, and protozoa produce cellulase, but humans and animals do not.
