Marinomonas lutimaris sp. nov., isolated from a tidal flat sediment of the East China Sea

A Gram-stain-negative bacterial strain, designated as E165T, was isolated from a tidal flat sediment of the East China Sea. Strain E165T grew optimally at pH 6, at 32 °C and with 1-2 % (w/v) NaCl. The 16S rRNA gene sequence similarity results revealed that strain E165T was most closely related to Marinomonas rhizomae IVIA-Po-145T, Marinomonas polaris CK13T, Marinomonas foliarum IVIA-Po-155T, Marinomonas hwangdonensis HDW-15T, Marinomonas pontica 46-16T, Marinomonas mangrovi B20-1T and Marinomonas shanghaiensis DSL-35T with values of 97.0-98.5 %. The digital DNA-DNA hybridization and average nucleotide identity values between strain E165T and the reference strains were 21.9-34.3 % and 77.6-87.3 %, respectively. The DNA G+C content of the isolate was 42.9 mol%. Strain E165T contained Q-8 as the sole ubiquinone and C16 : 0, summed feature 8 (C18 : 1  ω7c and/or C18 : 1  ω6c) and summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c) as the major fatty acids. The major polar lipids of strain E165T were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, aminolipid and aminophospholipid. On the basis of phenotypic characteristics, phylogenetic analysis and DNA-DNA relatedness, a novel species, Marinomonas lutimaris sp. nov., is proposed with E165T (=MCCC 1K06241T=KCTC 82809T) as the type strain.
