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

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

cel·lu·lase

(sel'yū-lās)
An enzyme catalyzing the hydrolysis of 1,4-β-glucoside links in cellulose. 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.
