The isolate grew optimally at 22 °C and minimum and maximum temperature of growth were 4 and 37 °C, respectively. It required Na+ for growth and exhibited optimum growth at pH 8·5 and 4 % NaCl. It utilized hexane, heptane and petroleum ether as sole sources of carbon. Strain CK 47T had Q9 as the major respiratory quinone and C16 : 0 (21·7 %), C17 : 0 (21·3 %), C18 : 0 (5·7 %), C18 : 1 ω7c (9·0 %) and C18 : 1 ω9c (31·4 %) as predominant fatty acids. The G+C content of the DNA was 58 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that CK 47T formed a coherent cluster within the genus Marinobacter. It exhibited highest 16S rRNA gene sequence similarity of 96·8 % with Marinobacter lipolyticus. However, the level of DNA–DNA relatedness between strain CK47T and M. lipolyticus was only 55 %. On the basis of phenotypic characteristics, and phylogenetic and genotypic distinctiveness, strain CK 47T is considered to represent a novel species of the genus Marinobacter. The name Marinobacter maritimus sp. nov. is proposed, with CK 47T (=JCM 12521T=MTCC 6519T) as the type strain. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.63478-0
