Abstract

The renewed interest in cellulase biotechnology is drawing the attention of researchers globally due to their diverse range of applications. The major applications of cellulases (E.C.3.2.1.4) are in textile and detergent industry. Additionally, they are in huge demand in food and feed sector for the improvement in digestibility, in nutritional quality of food/feed material, and in paper industries as de-inking agents. Another most promising application of cellulases is in the bioconversion of renewable lignocellulosic biomass into fermentable sugar constituents that are subsequently used for the production of value-added chemicals after the fermentation reaction with appropriate microorganisms. The success of ethanol-based biorefinery truly depends upon the efficiency of cellulase titers stable at high temperature and their cost at shop floor. Looking at the applications of cellulases, stable and active thermostable cellulases at high pH range would be more advantageous as compared to thermolabile enzymes in terms of time, cost savings, and getting the suitable product with desired yields/productivities. Recent developments on the proteomics, genomics, and fermentation strategies have paved the way for searching more efficient and novel thermostable cellulase titers from thermophilic microorganisms of different habitats.
