Biomass have gained much attention as a new sustainable energy source alternative to petroleum-based fuels. The second-generation bioethanol from lignocellulosic materials became a promising approach since the lingo-celluloses are not directly in competition with food sources. The present study focused on screening the Enterobacter species isolated from environment for hemicellulytic activity on beech wood, hard wood, bagasse and wheat straw. The optimization of pH, Temperature, Ratio of feedstock to water and feedstock to microbe concentration was analyzed. Optimum temperature, pH and substrate concentration for hydrolysis for feed stocks was found to be 32°C, 7.4 pH, 8.0 g and 250 ml feedstock to water. An ethanol yield of 2.3% v/v for beech wood, 2.1% v/v for hard wood, 1.92 % v/v for bagasse & 1.7% v/v for wheat straw was obtained for 8.0% of the feedstock.
