  • Cellulase refers to a class of enzymes produced chiefly by fungi, bacteria, and protozoans that catalyze the hydrolysis of cellulose. However, there are also cellulases produced by other types of organisms as plants and animals. Several different kinds of cellulases are known, which differ structurally and mechanistically.
  • In the most familiar case of cellulase activity, the enzyme complex breaks down cellulose to beta-glucose. This type of cellulase is produced mainly by symbiotic bacteria in the ruminating chambers of herbivores. Aside from ruminants, most animals (including humans) do not produce cellulase in their bodies, and are therefore unable to use most of the energy contained in plant material.
  • Enzymes which hydrolyze Hemicellulose are usually referred to as hemicellulase and are usually classified under cellulase in general. Enzymes that cleave lignin are occasionally classified as cellulase, but this is usually considered erroneous.
  • Cellulase is used for commercial food processing in coffee. It performs hydrolysis of cellulose during drying of beans. Furthermore, cellulases are widely used in textile industry and in laundry detergents. They have also been used in the pulp and paper industry for various purposes, and they are even used for pharmaceutical applications.
  • Cellulase is used in the fermentation of biomass into biofuels, although this process is relatively experimental at present. Cellulase is used as a treatment for Phytobezoars, a form of cellulose bezoar found in the human stomach.
  • Most cellulases studied have similar pH optima, solubility andamino acid composition. Thermal stability and exact substratespecificity may vary. However, it should be remembered that cellulase preparations generally contain other enzymatic activites besides cellulase, and these may also affect the properties of the preparations.
  • Successful utilization of cellulosic materials as renewable carbon sources is dependent on the development of economically feasible process technologies for cellulase production, and for the enzymatic hydrolysis of cellulosic materials to low molecular weight products such as hexoses and pentoses.
  • Cellulase is an inducible enzyme. Sophorose, a decomposition product of crystalline cellulose, is thought to be an indispensable inducer of cellulase activity. Although cellulase culture has been investigated with the use of Avicel and other crystalline celluloses as carbon sources, cheaper carbon and nitrogen sources are desired in order to lower production costs.
  • As a replacement for gasoline, ethanol could be made from cellulose at a greater quantity and lower cost than the current technology of corn. The anaerobic bacterium Clostridium thermocellum is an excellent candidate for conversion of renewable cellulose biomass to ethanol because it is a robust thermophile with stable enzymes.
  • Cellulases have had the most impact on textile processing in recent years. Current commercial applications include "biostoning", "biopolishing" and as laundering "brightners" of cotton fabrics. However, there is a fine balance between producing the desired effect and causing excessive damage to the fibres leading to an unacceptable loss in strength.
