Abstract：
:Three dominant types of sugar-fermenting bacteria were isolated from the anaerobic, intertidal sediments of the Eems-Dollard estuary by applying techniques involving anaerobic agar shake tubes. One of the isolated types was tentatively identified as aStreptococcus species, the other two asBacteroides species. All types were versatile with respect to the utilization of sugars. The fermentation patterns of two types were dependent upon conditions of cultivation. In glucose-limited cultures ofStreptococcus strain NS.G52, the production of lactate was suppressed in favor of formate, acetate, and ethanol. In glucose-limited syntrophic cultures withMethanospirillum hungatei, Bacteroides strain NS.G42 was forced to produce acetate and hydrogen at the expense of ethanol. The fermentation pattern ofBacteroides strain NS.S42, which consisted of acetate, propionate, and succinate, was not affected by conditions of cultivation.
