title: Algoriella xinjiangensis gen. nov., sp. nov., a new psychrotolerant bacterium of the family Flavobacteriaceae.
abstract: An aerobic, Gram-stain negative, non-spore-forming and psychrotolerant bacterium, designated strain XJ109(T), was isolated from a sewage water sample collected from Xinjiang Uigur Autonomous Region, China. Phylogenetic analysis based on 16S rRNA gene sequence indicated that strain XJ109(T) represents a novel member of the family Flavobacteriaceae. The strain showed 95.5 % similarity with the 16S rRNA gene sequence of Empedobacter brevis LMG 4011(T), 95.4% with Chishuiella changwenlii BY4(T), 95.3% with Empedobacter falsenii NF 993(T) and 92.3% with Weeksella virosa DSM 16922(T). Strain XJ109(T) showed the common phenotypic and chemotaxonomic characteristics of the family Flavobacteriaceae, containing menaquinone-6 (MK-6) as the predominant respiratory quinone and iso-C17:0 3OH and iso-C15:0 as the major fatty acids. The polar lipid profile consisted of phosphatidylethanolamine, one unidentified phospholipid and two unidentified lipids. The genomic DNA G+C content was 38.0 mol%. Strain XJ109(T) was positive for catalase and oxidase activities, and it was observed to grow at 4-30 °C (optimal 16-20 °C), pH 6.5-10.0 (optimal 7.0-7.5) and in media containing 0-2.0% (w/v) NaCl (optimal 0.5 %). On the basis of the polyphasic evidence presented, strain XJ109(T) is considered to represent a novel genus and species of the family Flavobacteriaceae, for which the name Algoriella xinjiangensis gen. nov., sp. nov. is proposed. The type strain is XJ109(T) (=CGMCC 1.10229(T)=JCM 16590(T)).
