Abstract

A novel Gram-stain-negative, non-spore-forming, obligate aerobic, motile, rod-shaped, and flagellated bacterium, designated S11R28, was isolated from the intestinal tract of a Korean shiner, . Based on 16S rRNA gene sequences, strain S11R28 was identified as member of the genus in class , and was closely related to DSM 23061 (98.49 %). The isolate grew at 4–25 °C, pH 6–9, with 0 % (w/v) NaCl, and grew optimally at 20 °C, pH 8, in the absence of NaCl. The main cellular fatty acids were C and summed features 3 (Cω7 and/or Cω6). The strain possessed diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylethanolamine as predominant polar lipids, and ubiquinone Q-8 as a respiratory quinone. The polyamine profile composed of 2-hydroxyputrescine, spermidine, putrescine, and benzoic acid. A genomic DNA G+C content was 51.4 mol%. The average nucleotide identity between strains S11R28 and DSM 23061 was 78.66 %. Thus, can be considered a novel species within the genus with the type strain S11R28 (=KCTC 62668=JCM 33224).
