Utilization of waste ripe Banana, and peels for Bio ethanol production using Saccharomyces cerevisiae
2011
Dried and ground peel biomass, ripe waste banana and Hydrolyzed peels of green and red banana used for bio ethanol production by Saccharomyces cerevisiae with shake flask culture. The substrate was given with different concentration as 1%, 2.5%, 5%, 7.5% and 10% (w/v) along with 1% inoculum. Saccharomyces cerevisiae exhibited maximum yield of ethanol in ripened red banana and their hydrolyzed peels about 1.3% and 0.27% (v/v) in 10% substrate concentration. The minimum yield about 0.02% of alcohol was produced in green un hydrolyzed banana peels with 1% substrate concentration. Conversion of reducing sugar range was 21% (g %) in un hydrolyzed green banana peels and maximum of 76% in red ripened banana as a substrate.
