Abstract
Production of easily fermentable low-cost sugars demands for an economic and less expensive method of enzymatic hydrolysis of cellulosic biomass. It is highly desirable to compare various fermentation media with different carbon sources for cellulase production. Trichoderma harzianum was grown on different carbon sources and monitored for cellulase production. Glucose-grown cultures of T. harzianum showed high amount of mycelial growth but no yield of cellulase enzyme. Cellulase expression was also studied herein by comparing the cellulase activities using soluble and insoluble cellulosic carbon sources in the growth media in order to obtain less expensive fermentation media. Outcome of the research will be helpful in the development of low cost system for production of cellulose.
