The world is gaining a lot of interest in the production of bioethanol from various biobased, agricultural waste sources in order to reduce net carbon dioxide emissions and lower the global dependence on fossil fuels. Lignocellulosic materials were a good choice as a feedstock for ethanol production considering their incredible accessibility and their ethanol yields. Rice straw is one of the major agro-waste which is produced during rice processing. This demonstrates the potential of using such waste materials for further processing, particularly in the production of bioethanol. The goal of this research is to make bioethanol from rice straw. For fermentation, rice straw hydrolysate was produced and inoculated with Saccharomyces cerevisiae. After fermentation, the fermented samples were qualitatively checked for the confirmation of bioethanol production and quantitatively estimated by the specific gravity method. Effects of various parameters like temperature, incubation period, and inoculum were also optimized to enhance bioethanol production. The highest bioethanol was obtained when 1% inoculum size was taken at 30℃ for 72 h.
