Production of bioethanol from starch in 10L bioreactor
MetadataShow full item record
Since oil is expected to last until 2025, the other alternatives should be finding so that this problems can be settle and discover new resources. Bioethanol is the one of renewable sources that can be used as a transportation fuel to cover the petroleum demand. Cassava is one of the materials that can produce biofuel as an alternatine energy sources. The production of bioethanol by using cassava was done by using the 10L bioreactor of ethanol production rig. The bioethanol production is produced throughout the fermentation process by using the Saccharomyces cerevisae and with the different of enzyme and inoculums concentration. The highest glucose production was obtained by using the 30% starch slurry. For the highest ethanol produced is by using the 0.25% α-amylase and 0.15% amyloglucosidase. For fermentation condition, 30% slurry is fixed to get better glucose consumption by S.cerevisae. However, the 15 % inoculum was considered adequate for the conversion of glucose to ethanol when the concentration of slurry used is 30%.
