Abstract: Potato peel waste (PPW) is a zero value by product, which occurs in big amounts after industrial potato processing and can range from 15-40 % of initial product mass, depending on the peeling method. PPW has contained high starch content and could be utilized for bioethanol production. Four yeast isolates were used for optimization of conditions by SHF method for ethanol production from potato peel wastes at different temperatures (30, 35 and 40°C), pH (5.0, 6.0 and 7.0) and incubation period under stationary condition. Maximum bioethanol production was observed from PPW at temperature 35°C and pH 6.0 after 72 h of incubation. SSF of PPW was observed at temperature 35°C and pH 6.0 after 72 h of incubation period using YPO3 and YPmp3. Maximum ethanol 2.83% was observed by using YPO3 after 72 h of incubation, whereas 3.75% was observed using Saccharomyces cerevisiae after 48 h of incubation from PPW.
