Growth was observed at temperatures from 10 to 40 °C (optimum 30 °C), at salinities from 0.5 to 6 % (optimum 2–3 %), and at pH from 5 to 8 (optimum 6). Phylogenetic analysis based on 16S rRNA gene sequence revealed that strain M11-4T shared highest sequence similarity with the genus Marinobacter (92.5–95.0 %) and represented a distinct phylogenetic lineage in the family Alteromonadaceae . The G+C content of the genomic DNA was 58.2 mol%. The dominant fatty acids were C16 : 0, C16 : 0 N-alcohol, summed feature 9 (comprising iso-C17 : 1ω9c and/or C16 : 0 10-methyl) and summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c). The predominant respiratory quinone was ubiquinone-9 and the major polar lipids were diphosphatidylglycerol; phosphatidylethanolamine; phosphatidylglycerol and an unidentified aminophospholipid. According to its morphology, physiology, fatty acid composition and 16S rRNA gene sequence analysis, the strain M11-4T should be assigned as a novel species of a novel genus for which the name Mangrovitalea sediminis gen. nov., sp. nov. is proposed. The type strain of Mangrovitalea sediminis is M11-4T (=MCCC 1K03312T=JCM 32104T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002433
