Butanol and ethanol could be good alternative biofuels for transportation. The bio- butanol and ethanol can be produced simultaneously in cultures of solventogenic Clostridium species through the acetonebutanol-ethanol (ABE) fermentation. For the isolation of microorganism capable of producing only butanol and ethanol without the acetone production, tidal flat samples were collected from seashore area of Tae-An, Korea. The isolated bacterium was designated Clostridium sp. nov. BS-5 and its 16S rDNA revealed 96% similarity to Clostirdium algidixylanolyticum SPL73T. Clostridium sp. nov. BS-5 produced acetone, ethanol, butanol, acetic acid, and butyric acid using glucose as a carbon source. To improve alcohol production, P2 medium modified with 3% sea salt was used and 0~50 g/L of yeast extract was initially added to investigate the effects of trace nutrients on two alcohol production. Ethanol and butanol concentration increased by the addition of yeast extract, up to 20 g/L. Clostridium sp. nov. BS-5 produced 14.71 g/L of alcohols with the yield of 0.54 g/g (0.20 g/L/hr). This result shows that Clostridium sp. nov. BS-5 is a promising new microorganism for two alcohol production.
