sp. nov., a floc-forming betaproteobacterium isolated from an activated sludge system treating coke plant effluent Free

Abstract

A Gram-negative-staining, short-rod-shaped, floc-forming bacterium, designated strain RB3-7, was isolated from a laboratory-scale activated sludge system treating coke plant effluent. Comparative analysis of the 16S rRNA gene sequence demonstrated that the novel isolate was distantly related (≤95.8 % similarity) to K11 within the family . Strain RB3-7 was catalase- and oxidase-positive and non-motile. The predominant fatty acids were C, cyclo C, Cω7 and Cω7, and the major respiratory quinone was Q-8. The G+C content of the genomic DNA of strain RB3-7 was 68.5 mol%. On the basis of phenotypic, chemotaxonomic and molecular data, strain RB3-7 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is RB3-7 ( = DSM 21699 = NCAIM B 02336).
