Pseudobowmanella zhangzhouensis gen. nov., sp. nov., isolated from the surface freshwater of the Jiulong River in China

摘要

A strain, JS7-9T, which was isolated from the surface freshwater of the Jiulong River, China, was subjected to taxonomic study. The bacterium was Gram-negative, facultatively anaerobic, rod-shaped and motile by means of a single polar flagellum. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JS7-9T is affiliated to the family Alteromonadaceae, showing 90.5–94.2 % of 16S rRNA gene sequence similarity with the genera Bowmanella (94.0–94.2 %), Aestuariibacter (93.0–93.5 %), Glaciecola (91.0–93.1 %), Alteromonas (90.5–93.1 %) and Salinimonas (90.6–91.8 %). The major fatty acids were identified as C16:0, Sum In Feature 3 (C16:1 ω7c/ω6c), Sum In Feature 8 (C18:1 ω7c/ω6c) and C17:1 ω8c, and Q-8 as the predominant isoprenoid quinone. Based on the phenotypic, chemotaxonomic and phylogenetic distinctiveness, strain JS7-9T is considered to represent a novel species of a novel genus of the family Alteromonadaceae, for which the name Pseudobowmanella zhangzhouensis gen. nov., sp. nov. is proposed, with the type strain JS7-9T (=MCCC 1A00758T = KCTC 42143T).
