Summary
Eight alcohol producing yeast strains were screened for their sedimentation rates and it was found thatS.cerevisiae NCIM 3526 was a better flocculant strain. This strain was employed in cane molasses fermentation with yeast recycle, supplemented with skim milk, chitin and fungal mycelium individually or in combination, at 30°C, using fermentable sugars 15%. On the completion of ten 16 h cycles, 20–30% more ethanol was produced in presence of these supplements and the efficiency of the process was improved from 66 to 87%.
