KEYWORDS: Lignocelluloses wastes. municipal wastes, cassava peels, saccharamyce cerevisae and ethanol


lignocellulosrc wastes (municipal wastes and cassava peels) were hydrolyzed with enzymes (cellulase and glycosidase) and fermented b ethanol using saccharamyce cerevisae. The amount of ethanol produced was found to be both substrate and concentration deper1dent. Higher yields of ethanol were obtained with less crystalline wastes. Higher yields of ethanol were obtained with cassava peels than with municipal wastes. In both case the best yields of ethanol were in the presence of glucose and acid-hydrolyzed starch In both cases. the fermented wastes gave higher protein content than the unfermented wastes. The possibility of employing the fermented products food and animal feed supplement is suggested. The feasibility of employing the cassava peels and municipal wastes as sources of ethanol or alcoholic beverages is also worth consideration.
