Enterobacter cloacae GAO, a hydrogen-producing and leavening bacterium, produced a large amount of succinic acid in a culture broth. To investigate the relationship between succinic acid and hydrogen production, the organic acids in a culture broth of 5 strains belonging to Enterobacteriaceae were analyzed. E.cloacae GAO produced the largest quantity of succinic acid among the strains tasted. The α-ketoglutarate dehydrogenase activities, which are related to succinic acid metabolism, were examined in the 5 strains. The highest enzyme activity was detected in E.cloacae GAO. Therefore, succinic acid may play a role in hydrogen gas production.
