DIRECT CONVERSION OF CELLULOSIC MATERIAL TO ETHANOL BY THE INTERGENERIC FUSANT TRICHODERMA-REESEI QM-9414 SACCHAROMYCES-CEREVISIAE NCIM-3288

Single-stage direct bioconversion of cellulosic materials to ethanol, under almost the same fermentation conditions applied to the Saccharom yces cerevisiae-ethanol process, was attempted using intergeneric fusa nts of Trichoderma reesei QM 9414/S. cerevisiae NCIM 3288. Optimizatio n of medium constituents, was made using the Box-Behnken design method . The combined effect of pH and temperature on the fermentation was an alyzed by the central composite design method. Under optimal condition s the fusant produced 0.17 gl(-1) ethanol in 30 h.
