| Abstract |
A Gram-stain-negative, non-spore-forming, rod-shaped and non-motile bacterium, designated strain xz20T, was isolated from the wastewater of a municipal wastewater treatment plant in Xuzhou, China. The taxonomic status of strain xz20T was determined using a polyphasic approach. Growth occurred at 15-40 °C (optimum, 25-37 °C), at pH 6.0-8.5 (optimum, pH 7.0) and with 0-3 % (w/v) NaCl (optimum, 1-2 %). 16S rRNA gene sequence analysis revealed that strain xz20T was a member of the genus Flavobacterium and shared the highest similarity with Flavobacterium. dongtanense LW30T (95.85 %) and Flavobacterium. haoranii LQY-7T (95.20 %). The major respiratory quinone of strain xz20T was menaquinone 6 (MK-6), and the major fatty acids were iso-C15 : 0, iso-C15 : 1 G and summed feature 9 (iso-C17 : 1ω9c and/or C16 : 0 10-methyl). The major polar lipid was phosphatidylethanolamine. The genomic DNA G+C content of strain xz20T was 32.9 mol%. Based on the phenotypic, phylogenetic and chemotaxonomic characteristics, strain xz20T represents a novel species belonging to the genus Flavobacterium, for which the name Flavobacterium luticocti is proposed. The type strain is xz20T (=CCTCC AB 2015421T=JCM 31174T).
