Abstract: Rice straws and Husks were converted to reducing sugars by hydrolysis using concentrated sulphuric
acid followed by fermentation using bakers yeast. After fractional distillation and purification, 52 ml (87 %) of
ethanol was obtained from 480cm3 of biomass which was blended with gasoline using different ratios. Physical
constants of the bio-ethanol (density and distillation) conformed to Kenya Bureau of Standards specifications.
The conclusion is that the bioconversion offers a cheap and safe method of disposing the agricultural residues
and conversion of lignocellulosic wastes into ethanol.
