Production of Bio-fuel (Bio-ethanol) from Biomass (Pteris) by Fermentation Process with Yeast

Bio-Ethanol is a renewable; eco-friendly energy source can be produced from bio-mass (hemicelluloses). Pteris (fern) is grown very fast and has not major economic importance but it is a reliable source of hemicelluloses can be converted to bio-Ethanol. In the hydrolysis of hemicelluloses the concentration of glucose and the reaction rate was observed with respect to the different parameters, like pH, temperature, substrate diameter, substrate loading. In this study we found optimal parameters, NH4OH treatment as the best treatment among H2SO4, NH4OH, and NaOH treatment. In addition, pH 7, temperature 35 oC, substrate diameter 45 μm-63 μm, and substrate loading 0.25gm in 100 ml working volume was found as optimum operation condition for hydrolysis reaction, which was carried out by…
