sp. nov., isolated from coastal sediment Free

Abstract

A novel Gram-stain-negative, non-gliding, facultatively anaerobic and rod-shaped bacterium, designated X7, was isolated from marine sediment taken from the coast of Weihai, China. Strain X7 grew optimally at 28–30 °C, at pH 7.0 and in the presence of 2–3 % (w/v) NaCl. Based on the 16S rRNA gene sequence analysis, strain X7 was a member of the genus and was most closely related to the species with a 96.3 % 16S rRNA gene sequence similarity value. The major cellular fatty acids of strain X7 were anteiso-C, iso-C, anteiso-Cω9, iso-Cω9, C 2-OH and iso-C 3-OH. The major polar lipids of strain X7 were phosphatidylethanolamine, one unidentified phospholipid, two unidentified aminolipids and five unidentified lipids. The predominant respiratory quinone was MK-6, and the genomic DNA G+C content was 46.7 mol%. Phylogenetic, phenotypic, chemotaxonomic and genotypic results indicated that strain X7 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is X7 (=KCTC 42585=MCCC 1H00115).
