Hydrochloric acid pretreated agro wastes as carbon source on CM-cellulases production by Aspergillus niger

Abstract

Cellulase is a multi-component enzyme system that works synergistically in hydrolyzing the cellulosic substrates to glucose. Mostly three enzymes are involved; endo-β-d-glucanase (EC 3.2.1.4) which catalyzes the random hydrolysis of soluble and insoluble cellulose chains. Exo-β-d-glucanase (EC 3.2.1.19) aids in releasing cellobiose from reducing and non-reducing ends of cellulose, and hydrolysis of cellobiose to glucose is carried out by β-glucosidase (EC 3.2.1.37).1,2 Cellulases have been used in a number of industrial processes. The most notable applications are in textile, paper and pulp, food and animal feed, fuel and chemical industry, waste management, and pharmaceutical industry.3
