Résumé / Abstract

Clostridium butyricum could produce hydrogen from a sweet potato starch residue upon supplementation of nitrogen sources. A repeated batch culture using a mixed culture of C. butyricum and Enterobacter aerogenes produced hydrogen with a yield of 2.4 mol H₂/mol glucose under a controlled culture pH of 5.25 in a medium consisting of the sweet potato starch residue and 0.1% Polypepton without addition of any reducing agents. Rhodobacter sp. M-19 produced hydrogen from the supernatant of the culture broth obtained in the repeated batch culture containing C. butyricum and E. aerogenes when 50 μg/l Na₂MoO₄.2H₂O and 20 mg/l EDTA were added to the supernatant and it was cultured under a controlled culture pH of 7.5. A high yield of hydrogen of 7.0 mol H₂/mol glucose from the starch remaining in the starch residue was attained in two-step repeated batch cultures containing C. butyricum and E. aerogenes, and by Rhodobacter sp. M-19.
