A Gram-negative-staining, short-rod-shaped, floc-forming bacterium, designated strain RB3-7(T), was isolated from a laboratory-scale activated sludge system treating coke plant effluent. Comparative analysis of the 16S rRNA gene sequence demonstrated that novel isolate distantly related (≤ 95.8 % similarity) to Ottowia thiooxydans K11(T) within family Comamonadaceae. Strain RB3-7(T) catalase- and oxidase-positive non-motile. The predominant fatty acids were C₁₆:₀, cyclo C₁₇:₀, C₁₈:₁ω7c C₁₆:₁ω7c, major respiratory quinone Q-8. G+C content genomic DNA 68.5 mol%. On basis phenotypic, chemotaxonomic molecular data, is considered represent species genus Ottowia, for which name pentelensis sp. nov. proposed. type ( = DSM 21699(T) NCAIM B 02336(T)).
