The fractions which contained the sufficient high activity of cellobiase were separately pooled for further characterization.
Activity of cellobiase was determined at different temperatures ranging 5-35[degrees]C.
Based on the enzyme action mechanism recognized universally [43] and discussed above, the hydrolysis resulted from the synergistic effect of endoglucanase (EG), exoglucanase (cellobiohydrolases, CBH), and cellobiase (CB).
There is wide recognition that the enzyme hydrolysis is the result of cooperation of monocomponent [26, 27] enzyme, mainly including endoglucanases, exoglucanases, and cellobiases. Nevertheless, there are no explicit reports about the sharpening and shearing action on cellulose fibers during the mixed cellulase hydrolysis process.
The cellulases produced by fungi have three main components: endoglucanases that hydrolyze internal [beta]1,4 D-glycosidic bonds; the cellobiohydrolases (exocellulase) which produce cellobiose from nonreducing ends from cellulose; the [beta]-glucosidases (cellobiases) which convert cellobiose to glucose.
The b-D-glucosidase or cellobiase convert cellooligosaccharides and cellobiose to glucose (Dienes et al., 2004).

Cellulase is a multienzyme complex that consists of three major enzymes, endo-1, 4 glucanase, cellobiohydrolase and cellobiase (7).
The cellobiose is hydrolyzed by AY-glucosidase or Cellobiase into individual monosaccharides (Javed et al.
The major active enzymes of the preparation were [alpha]-1,6-[beta]-galactosidase, [beta]-1,4-mannanase and [beta]-1,4-mannosidase, although it also contains several minor residual enzymes including [beta]-1,4-glucanase, [beta]-1,4-glucosidase, cellobiase, xylosidase, arabinosidase, and amiloglucosidase.
High cellobiase and xylanase production by Sclerotium rolfsii UV-8 mutant in submerged culture.
These enzymes, such as avicelase, CMCase, xylanase and cellobiase, account for the primary reactants on dietary carbohydrates and proteins (Santra et al., 2007).
