Abstract

Cellulase protein, catalyses the conversion of cellulose to glucose in an enzymatic hydrolysis based biomass to ethanol process. The effect of various carbon sources on the production of cellulase were studied using Trichoderma reesei QM 9414 and RutC30. The carbon substrates namely lactose, cellulose, banana fiber and cotton fiber were used. Pretreatment of cotton fiber and banana fiber offers very digestible celluloFe. Cellulase production was enhanced by multiple carbon sources because of diauxic pattern of utilization of substrates. The Trichoderma reesei cellulase system is of a complex nature. Complete quantitative description of its behavior would lead to large sets of mathematical expressions defining the time evolution of large number of variables. Monod model is highly flexible and can be used to describe many complex profiles. Leudeking piret model is well exhibits the combination of both growth associated and non-growth associated and contributions, in the cellulase production.
