- 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.
