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.

cellulasean 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.
