Abstract

The bio-production of ethanol from sweet potato peel using microorganism was examined. Proximate analysis was carried out on the peel and the results from the analysis demonstrated that sweet potato peel contained sufficient amounts of starch and total carbohydrates to guarantee use for bio-ethanol production. To obtain maximum conversion of starch into fermentable sugars, sweet potato peel was hydrolysed by hydrochloric acid at different temperature and concentration. The effect of inoculum size, pH, temperature and time to obtain maximum ethanol from sweet potato peel waste were studied in batch fermentation. The maximum ethanol yield obtained was 6.39g/L at pH 5.0, temperature of 32.5⁰C and inoculums size of 6% (v/v) after 48 hours of fermentation. The results obtained showed that sweet potato peel which is a waste, can be a feedstock for bioethanol production.
