Comparative evaluation of ethanol production from sweet potato (lpomoea Batalas) and maize (Zea Mays).

About 200g (in powered form) of peeled, sliced, drkl; and ground samples of sweet potato, and maize were subjected to complete hydrolysis using /\z.ha ·, 1981 method. The filtrates (hydrolysates) from hydrolysis were later subjected to lcrmentatim1 process using Saccharomyce cerevisiae for 72-96 hours. Distillation was adopted to recover ethanol produced at 78°C. The average volume of ethanol produced from Red Potato, white potato and maize were 28.40ml, 30.00ml and 37.17ml respectively. Ethanol from maize had pl I value nr 3.6; Red potato, 4.0; White, 4.3. Percentage yield of ethanol was in the order: Maizc>White potato> Red potato as their values were 14.72%, 11.93% and I Ll9% respectively. The results showed that maire had the highest sugar content thus, highest percentage yield of ethanolenAttribution-NonCommercial-ShareAlike 4.0 InternationalEthanolproductionsweet potatomaize fermentationDepartment of BiotechnologyArticle
