Abstract
Sedimentation rates ranging from 58.82 to 93.10% were recorded for six palm wine Saccharomyces yeast isolates. Isolates S, J and A(3), gave values of 90.00, 91.95 and 93.10% respectively compared to 81.54% for a standard lager beer yeast. Fermentation of unclarified molasses medi um 10-30 degrees Brix with isolate J gave ethanol productivity of 74.3 5-67.07%. soyabean, groundnut or castor oil seed meal supplements sign ificantly enhanced ethanol productivity in all the molasses media.
