Abstract
In our earlier communications [1 – 4], studies on rapid fermentation of cane molasses into ethnaol in an immobilized cell column have been reported. In the present study ethanol fermentation of bagasse hydrolysate by a strain of Saccharomyces cerevisiae is described. The process was investigated in a continuous jacketted glass column packed with yeast cells immobilized on an inert carrier. Various feed glucose concentrations is bagasse hydrolysate were studied. A cell concentration of 365 mg per gram inert support was achieved. Maximum productivity of 23.17 gl −1 h −1 has been attained with a feed glucose concentration of 150 gl −1 during a residence time of 2.6 h. Conversion of glucose in the hydrolysate to ethanol with an efficiency of 97% of theoretical was achieved.
