cellulase

cel·lu·lase

C0191400 (sĕl′yə-lās′, -lāz′)n. Any of several enzymes produced chiefly by fungi, bacteria, and protozoans that catalyze the hydrolysis of cellulose.

[cellul(ose) + -ase.]

cellulase

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

cel•lu•lase

(ˈsɛl yəˌleɪs, -ˌleɪz)

n. any of several enzymes, produced primarily by fungi and bacteria, that catalyze the hydrolysis of cellulose. [1900–05]

Cellulase

cellulase

[′sel·yə‚lās] (biochemistry) Any of a group of extracellular enzymes, produced by various fungi, bacteria, insects, and other lower animals, that hydrolyze cellulose.

Cellulase

an enzyme of the hydrolase class. Cellulase depolymerizes cellulose polysaccharides (including cellulose itself) and forms glucose or the disaccharide cellobiose. Cellulase is found in germinated grain and in many bacteria and fungi; it is especially active in house fungi that grow on wood. Cellulase is also found in certain animals that feed on wood; these animals include shipworms and Cossidae. Ruminants are able to digest cellulose because symbiotic microorganisms that release cellulase live in the compartments of their stomachs, especially in the rumen.

cellulase

[sel´u-lās] a concentrate of cellulose-splitting enzymes derived from Aspergillus niger and other sources; used as a digestive aid.

cel·lu·lase

(sel'yū-lās), Enzyme catalyzing the hydrolysis of 1,4-β-glucoside links in cellulose, lichenin, and other β-d-glucans; found in a variety of microorganisms in soil and in the digestive tracts of herbivores. Used to produce digestive tablets and in the removal of cellulose from foods for special diets.

cellulase

an ENZYME capable of splitting CELLULOSE into glucose, used particularly in the softening or digestion of plant cell walls. Most animals are not capable of producing cellulase and therefore of digesting plant material themselves, relying instead on a variety of gut microorganisms to produce the enzyme and then absorbing the glucose product (see CAECUM). Cellulase is also produced in large quantities in the ABSCISSION layer formed in leaf stalks of higher plants, causing a weakening of cell walls prior to leaf fall.
