Abstract

Bioethanol is biodegradable, low toxicity and colourless liquid biofuel that can be produced through fermentation process from biomass feedstock and had become one of the most popular alternative source of energy to reduce the consumption of fossil fuel based energy. The aim of this research is to produce bioethanol from agriculture waste, corn stover through simultaneous saccharification and fermentation (SSF) process with the help of different pretreatment. Corn stover is a promising bioethanol producing raw material as it contain high level of lignocellulose, which can convert into glucose molecules through pretreatment process (size reduction, acid and alkaline) to increase the total surface area and decrease the biomass crystallinity for better enzymatic hydrolysis. In simultaneous saccharification and fermentation process, enzyme cellulase from Aspergillus niger is used in enzymatic hydrolysis while Saccharomyces cerevisae and Escherichia coli are used in fermentation process. After high performance liquid chromatography, Saccharomyces cerevisae show the highest concentration of bioethanol produced which is 33.45 % in alkaline condition.
