Production of Bio-Ethanol from Biomass (Press Mud)
This document gives formatting instructions for authors preparing papers for publication in the Proceedings Bioethanol is a renewable; eco-friendly energy source can be produced from bio-mass. Increasing the use of bio-ethanol for energy generation purposes is of particular interest now a day because they allow reducing the Greenhouse Gases (GHG). The production of low cost ethanol by using lignocelluloses material basically the sugar industry wastes like bagasse and press mud. Press mud was characterized as moisture (70-75%), ash (18.25%) and protein content (1.68 g/L). Press mud contains sufficient amount of cellulose (22.3%) and hemicelluloses (21.67%) so it has allure for use as a potential feedstock. Press mud drying study was also carried out to avoid microbial spoilage and increase storability. The acid hydrolysis of press mud with optimized parameters (H2SO4, 1.5 %; solid to liquid ratio 1:5 and time 15 min.) resulted in sugar release of 21 g/L. Furthermore, the activated carbon detoxification technique was carried out to remove phenolics, which are destructive to fermentation process. The batch fermentation of detoxified press mud using saccharomyces cerevisaie NRRL Y-12632 (pH-4.5, Temp- 28°C, RPM- 120, Time- 96 hrs.) resulted 11.65 g/l of total solvents. Hence, clean and green, effective utilization of press mud for bio-ethanol production successfully achieved.
