A fermentative hydrogen-producing anaerobe, strain SO5B. was isolated from soil, and from its taxonomical properties it was assumed to be a member of Enterobacteriaceae. The growing cells of die bacterium, precultured with starch, produced a larger volume of hydrogen from starch than from glucose. The best conditions for hydrogen production from starch were at an initial medium pH of around 7.0 and at an incubation temperature of 36 degrees C with stirring. Both heated and nonheated natural starches such as potato, corn, and wheat, starch were available to the growing cells for hydrogen production, although wheat starch gave a low yield. The hydrogen-producing ability of the cells was appreciably tolerant to oxygen. These properties are advantageous for the use of hydrogen production in elation to the microbial treatment of industrial organic wastewater
