The major respiratory quinone of strain XH134T was MK-6. The dominant fatty acids of strain XH134T were iso-C15 : 0, iso-C15 : 1 G, C16 : 1ω6c and/or C16 : 1ω7c, iso-C17 : 0 3-OH, iso-C15 : 0 3-OH and 10-methyl C16 : 0 and/or iso-C17 : 1ω9c. The polar lipids of strain XH134T comprised phosphatidylethanolamine, one unknown aminolipid and three unknown polar lipids. The DNA G+C content of strain XH134T was 32.4 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that the novel strain was related most closely to Aquimarina macrocephali JAMB N27T with 96.9 % sequence similarity. A number of phenotypic characteristics distinguished strain XH134T from described members of the genus Aquimarina . On the basis of combined phenotypic and phylogenetic analyses, strain XH134T represents a novel species of the genus Aquimarina , for which the name Aquimarina megaterium sp. nov. is proposed. The type strain is XH134T ( = CGMCC 1.12186T = JCM 18215T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.055517-0
