The prospective end-use of abundant waste and waste feedstocks of lignocellulosic biomass is attractive and promising for the production of both fuel and adsorbent. A straightforward method for ethanol production by saccharomyces cerevisiae using different amounts, temperatures, substrate
loading, fermentation time and with or without mild treatments was carried out. Higher yields of ethanol were obtained as the cell walls of the biomass with small particle sizes were exposed for the direct hydrolysis and fermentation.
