The partially purified 20-40% ammonium sulphate precipitate enzymes fraction and mouldy substrate were compared with crude enzyme extract to hydrolyze the alkali-treated wheat straw. The highest hydrolysis 82.8% was obtained using mouldy substrate. The enzymatic hydarolyzate containing 68% glucose of total sugars. The enzymatic hydrolyzate of the alkali-treated wheat straw was fermented for 48h by Saccharomyces cerevisiae and hybrid of S. cerevisiae has the ability to convert pentoses to enthanol 29.1 and 35.9 gram ethanol/100 g alkali-treated wheat straw were yielded by the two strains respectively.
