sp. nov., isolated from a marine solar saltern, and emended description of the genus Free

Abstract

A novel Gram-stain-negative, rod-shaped, beige-coloured, motile, facultatively anaerobic bacterium, designated as E84, was isolated from sediment sampled from a marine solar saltern in Wendeng, PR China. Phylogenetic analysis based on 16S rRNA gene sequencing showed that WDN1C137 was the closest phylogenetic relationship, with 16S rRNA gene sequence similarity of 96.9 %. Optimal growth occurred at 33–37 °C (range, 20–40 °C), at pH 7.5 (pH 7.0–8.5) and with 6.0 % (w/v) NaCl (0.5–20.0 %). The sole respiratory quinone was Q-10. The major fatty acids were summed feature 8 (Cω7 and/or Cω6), C and cyclo Cω8. The polar lipids were phosphatidylglycerol, one unidentified glycolipid, two unidentified phospholipids and two unidentified lipids. The genomic DNA G+C content of strain E84 was 69.8 mol%. Based on the results of physiological, genotypic, phylogenetic and chemotaxonomic analyses, we concluded that strain E84 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is E84 (=KCTC 52697=MCCC 1H00231).
