abstract= A novel Gram-negative, obligately aerobic, non-motile, rod-shaped bacterium, strain M97T, was isolated from marine sediment of a cage-cultured ark clam farm on the south coast of Korea. Strain M97T was positive for oxidase and catalase. Optimal growth occurred at 37 °C, with 1–2 % (w/v) NaCl and at pH 7–8. The main cellular fatty acids were C16 : 0, C18 : 1ω7c, C12 : 0 3-OH and cyclo-C19 : 0ω8c. The polar lipids comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, an unknown aminolipid and three unknown lipids. The predominant respiratory quinone was ubiquinone-10 (Q-10). Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain M97T belongs to the genus Tropicimonas , with highest sequence similarity to Tropicimonas aquimaris DPG-21T (99.0 %). The DNA G+C content of strain M97T was 68.5 mol%. Mean DNA–DNA relatedness between strain M97T and T. aquimaris DPG-21T was 46±10 %. Based on phylogenetic, phenotypic and genotypic analyses, strain M97T is considered to represent a novel species of the genus Tropicimonas , for which the name Tropicimonas sediminicola sp. nov. is proposed. The type strain is M97T ( = KACC 15544T = JCM 17731T).,
