Cellulases of Bacterial Origin and their Applications: A Review

The cellulosic biomass in the form of agricultural waste, is a renewable and abundant resource with great potential for bioconversion to value-added bioproducts. It can be degraded by cellulase produced by cellulolytic bacteria to more useful products, such as single-cell protein for use in animal feeds or ethanol for use as a fuel or chemical feedstock. . This enzyme has various industrial applications and therefore, there is resurgence in utilization of biomass for fuel production employing cellulases and hence forth in obtaining better yields and novel activities. Improving the economics of such processes will involve cost reduction in cellulase production which may be achieved by better bioprocesses and genetic improvement of cellulase producers to yield more of the enzyme. The review discusses application of cellulose and the types of cellulolytic bacteria.
