In this study, a stable microbial flora that anaerobically consumed alginate and produced fatty acids, mainly acetate, and ethanol was established by acclimation of various microbial sources such as soil and seaweed samples in Japan. The microbial flora was composed of three kinds of microorganisms named HUA-1 (64%), HUA-2 (32%), and HUA-3 (4%). From similarity of 16srRNA small subunit, it was suggested that they were relatives of Clostridium saccharolyticum (98%), Dysgonomonas capnocytophagoides (95%), and Citorobacter freundii (98%), respectively. Among them, HUA-1 and HUA-2 were consumers of alginate. However, although isolation of HUA-1 and HUA-2 was attempted using agar medium with alginate as a sole carbon source, only HUA-2 was isolated and grew at the similar specific growth rate as that of original flora, suggesting that HUA-1 could not grow on agar plate or could grow achieving a symbiotic relationship with HUA-2.
