| Abstract |
Gram-stain-negative, facultatively anaerobic, non-motile, non-spore-forming, rod-shaped bacterium, designated strain HUA-2T, was isolated from an alginate-degrading microbial consortium. Strain HUA-2T was related to Dysgonomonas capnocytophagoides JCM 16697T, Dysgonomonas macrotermitis JCM 19375T and Dysgonomonas mossii CCUG 43457T with 95.1 %, 94.1 % and 92.1 % 16S rRNA gene sequence similarity, respectively. The optimal growth temperature and pH for strain HUA-2T were 35 °C and pH 8.0, respectively. Enzyme production, major fermentation products from glucose, and the major cellular fatty acids were different from those of D. capnocytophagoides CCUG 17966T or other members of the genus Dysgonomonas. Therefore, strain HUA-2T is proposed to represent a novel species of the genus Dysgonomonas, for which we propose the name Dysgonomonas alginatilytica sp. nov. The type strain is HUA-2T ( = DSM 100214T = HUT 8134T).
