Definitions for "Cellulase"
Any enzyme that converts cellulose to the disaccharide cellobiose.
An enzyme complex that breaks down cellulose to beta-glucose. It is produced mainly by symbiotic bacteria in the ruminating chambers of herbivores. Aside from ruminants, most animals (including humans) do not produce cellulase and are therefore unable to use most of the energy contained in plant material.
(n) a enzyme that breaks down cellulose cellulose, the carbohydrate that is the main part of the cell walls of plants. Animals such as cows produce cellulase but humans do not. This is why cows can get nutrition from plants such as grasses, while humans can not. (See enzymes.)
