【 摘 要 】

Pakistan has large resources of sugarcane crops coupled with significant amount of molasses generated annually. In this study, the effects of enzyme zymase concentration (2-5 g/l), pH (5.5-6), aeration rate (0.1-0.2 vvm/l) and agitation speed (250-300rpm) were investigated for ethanol production. Saccharomy cesservisae was used as a biocatalyst. The maximum ethanol production of 82g/l was obtained at 0.2vvm/l, pH5.5, 300rpm and 35°C at 4g/l of enzyme. This study suggests a novel method of utilizing the enzyme separately for improving ethanol production.
