Current Advancements in Recombinant Technology for Industrial Production of Cellulases: Part-II

Abstract

Cellulase is the largest group of industrial enzyme used worldwide for the degradation of cellulose. Since many industries use this enzyme for the production of good quality of products, hence the demand for cellulase is increasing day by day. Cellulases are preferred for different purposes by industries which include paper recycling, cotton, textile, juice extraction, food, etc. Cellulases have some major enzymatic group components such as endoglucanases, exoglucanase and β-glycosidase. Different technologies are used for the production of cellulases, i.e. shake-flask experiments to fermentations, construction of improved cellulases, batch cellulase production and fed-batch cellulase production. Each method has its own limitations; considering these limitations, recombinant technology may play a valuable function in increasing the cellulase production. In present scenario, different industries are using the recombinant technology for the enhancement of cellulase production. The recombinant technology can help to produce cellulase more effectively than the other technologies which convert cellulosic biomass to glucose and other products. In nature, microorganism has the potential to produce cellulases, which enable the function of hydrolysing cellulose. However, recent reports claim that the plants, several molluscs such as snails, a periwinkle, Nudibranchia and a few bivalves also have the ability to yield cellulases. In this chapter, we have concluded how recombinant technology can help to manage the crisis of cellulases for various objectives and also improving the availability of biofuel.
