cel·lu·lase

 (sĕl′yə-lās′, -lāz′)
n.
Any of several enzymes produced chiefly by fungi, bacteria, and protozoans that catalyze the hydrolysis of cellulose.

cellulase

(ˈsɛljʊˌleɪz)
n
(Biochemistry) any enzyme that converts cellulose to the disaccharide cellobiose
[C20: from cellulose + -ase]

Regulation (Alteration) of activity and conformation of sucrase by coaggregation with cellobiase in culture medium of Termitomyces clypeatus.
After 10 days, crude enzyme was extracted by centrifugation and supernatant was analyzed for activities of carboxymethylcellulase, filterpaperasee and cellobiase by Mandels et al (1976) method.
For the production of glucose a third type of activity, cellobiase or [beta]-glucosidase (EC 3.2.1.21) is also required.
The enzymes, Cellulase (Celluclast 1.5L, Novozymes A/S, Denmark) and cellobiase (Novozym 188, Novozymes A/S, Denmark) were added at 60 FPU per g glucan loading (FPU = filter paper unit) and 64 pNPGU per g glucan (pNPG = p-Nitrophenyl [beta]-D-glucoside), respectively and incubated for 72 hours.
Due to the feedback inhibition of reaction kinetics, the abundance of glucose affected the rate of cellobiose hydrolysis by cellobiase (one of monoenzyme in the mixed cellulase).
This could be explained in terms of a poor cellobiase activity inside the enzymatic cocktail.

(2001) observed an increase in production of endoglucanase, filter paper activity and cellobiase in two to fourfold of mutated T.
Finally, cellobiase acts by cleaving the [beta]-1,4 glycosidic bond of cellobiose and small oligosaccharide molecules with release of monomeric sugars (WOOD; McCARE, 1979; BHAT, 2000).
