ABSTRACT
A Gram-negative, non-motile, non-spore-forming, aerobic and short rod-shaped bacterial strain R32T, was isolated from seawater of the South Atlantic Ocean. Strain R32T grew at 10-40 °C (optimum 28 °C), at pH 6.0-8.0 (optimum 7.0), and in the presence of 3-8â% NaCl (w/v) (optimum 5â%). Cells were oxidase- and catalase-positive. The 16S rRNA gene sequence of strain R32T shared the highest similarities with Mesonia oceanica (98.3â%), followed by Salegentibacter salarius (93.0â%), Salegentibacter mishustinae (92.8â%), Salegentibacter salegens (92.5â%) and Mesonia maritima (92.4â%). The dominant fatty acids were iso-C15ââ0 (32.7â%) and iso-C17ââ0 3-OH (21.1â%). Menaquinone-6 (MK-6) was detected as the sole respiratory quinone. The polar lipids found were phosphatidylethanolamine, three aminolipids and three unidentified lipids. The DNA G+C content was 35.0 mol%. The ANI value and dDDH value between strain R32T and the Salegentibacter and Mesonia species were 70.5-85.8â% and 18.7-30.5â%, respectively. Based on the results of the polyphasic characterization, strain R32T is considered to represent a novel species of the genus Mesonia, for which the name Mesonia hitae sp. nov. is proposed. The type strain is R32T (=MCCC 1A09780T=KCTC 72004T).
