Abstract
Cassava and sweet potato pulps and starches have been show to contain the following sugar: hydrolysed and unhydrolysed cassava pulp and starch – maltose and glucose; hydrolysed and unhydrolysed sweet potato pulp – maltose, glucose, sucrose, fructose and rharnose; hydrolysed sweet potato starch – maltose and glucose. An unidentified sugar was suspected to be present in both the cassava and sweet potato pulps. A strain of Saccharomyces cerevisiae has been isolated from palm wine. The alcohol tolerance of this strain was quite high – 9.3 (v/v). It fermented blackstrap molasses more efficiently than Baker’s Yeast. It also ferments hydrolysed cassava and sweet potato pulp and starches quite efficiently. The major fermentation product in each case was found to be ethanol
