sp. nov., isolated from intertidal sediment No Access

Abstract

A Gram-stain-negative, aerobic, flagellated, and long rod-shaped bacterium, designated strain SM1973, was isolated from an intertidal sediment sample collected from the coast of Qingdao, PR China. Strain SM1973 grew at 15–37 °C and with 0–5.5 % NaCl. It reduced nitrate to nitrite and hydrolysed aesculin but did not hydrolyse casein and gelatin. The strain showed the highest 16S rRNA gene sequence similarity (98.2 %) to the type strain of . The phylogenetic trees based on the 16S rRNA genes and single-copy orthologous clusters showed that strain SM1973 clustered with , forming a separate lineage within the family . The major cellular fatty acids were summed feature 3 (C 7 and/or C 6) and C. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The main respiratory quinone was ubiquinone-9. The genomic DNA G+C content of strain SM1973 was 40.4 mol%. Based on the polyphasic evidence presented in this paper, strain SM1973 is considered to represent a novel species within the genus , for which the name sp. nov. is proposed. The type strain is SM1973 (=MCCC 1K04833=KCTC 72846).
