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.

Using the transgenically-produced enzyme technology, the appropriate cellulase and beta-galactomannanase enzymes in prescribed doses, all it takes is to mix the enzyme powder with the copra meal in the usual dry form-with the enzymes doing their work when the animal eats the feed, releasing more nutrients from copra meal than can ever be achieved by fermentation; no ancillary equipment needed, and at lesser cost.
Cellulase and [beta]-glucosidase are important enzymes related to the carbon (C) cycle, because cellulose is one of the most abundant organic compounds in the biosphere (Falkowski et al.
