Abstract:
Cellulases are hydrolytic enzymes that catalyze total hydrolysis of cellulose into sugars. Cellulases are produced by various groups of microorganisms and animals; however, psychrophiles are the ideal candidates for the production of enzymes active at low temperature and stable under alkaline conditions, in the presence of oxidants and detergents, which are in large demand as laundry additives. The cellulases from psychrophiles also find application in environmental bioremediation, food industry and molecular biology. Research work on cellulase has been done over the last six decades, but there is no exclusive review available on the cellulases from psychrophiles. This review is an attempt to fill this gap by providing all the relevant information exclusively for cellulases from psychrophiles, with a focus on the present status of knowledge on their activity, molecular characteristics, gene cloning, statistical experimental designs, crystal structure, and strategies for the improvement of psychrophilic cellulases.
