Sedimentation Characteristics and Effect of Molasses Concentration and Medium Supplementation on the Ethanol Productivity of an Ethanol Tolerant Palm Wine Saccharomyces
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 medium 10-30 degrees Brix with isolate J gave ethanol productivity of 74.35-67.07%. soyabean, groundnut or castor oil seed meal supplements significantly enhanced ethanol productivity in all the molasses media.
