- Abstract
A Gram-negative, rod-shaped, motile bacterium, designated strain CAU 1620T, was isolated from a tidal flat sediment in Incheon, Republic of Korea. Strain CAU 1620T grew optimally at 30 °C and pH 8.0 in the presence of 6.0% (w/v) NaCl. The results of 16S rRNA gene sequence analysis revealed that strain CAU 1620T showed the highest similarity to Marinobacter adhaerens DSM 23420T (98.5%), followed by Marinobacter algicola DSM 16394T (98.3%) and Marinobacter maroccanus LMG 30465T (98.2%). The average nucleotide identity and digital DNA–DNA hybridisation values between strain CAU 1620T and related strains were estimated as 75.6–78.1% and 19.5–20.9%, respectively. The DNA G + C content based on the draft genome sequence was 59.2%, and the major respiratory quinone was ubiquinone-9. The predominant cellular fatty acids were C12:0, C16:0, C18:1ω9c, and C12:0 3OH. The predominant polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, and phosphatidylglycerol. According to phenotypic, genotypic, and chemotaxonomic analyses, strain CAU 1620T represents a novel species of the genus Marinobacter, for which the name Marinobacter arenosus sp. nov. is proposed. The type strain is CAU 1620T (= KCTC 82431T = MCCC 1K06079T).
