Phylogenetic analysis based on 16S rRNA gene sequences revealed that the novel strains were closely related to Maritalea myrionectae CL-SK30T (97.9 % 16S rRNA gene sequence similarity) and Zhangella mobilis E6T (96.2 %). 16S rRNA gene sequence similarity between Z. mobilis E6T and M. myrionectae CL-SK30T was 97.9 %. The DNA G+C contents of the isolates (49.4–50.0 mol%) were similar to those of M. myrionectae DSM 19524T (52.3 mol%) and Z. mobilis JCM 15144T (50.3 mol%). From these results, it was difficult to differentiate the genus Zhangella from the genus Maritalea. DNA–DNA hybridization demonstrated that the isolates belonged to a single species. The isolates could also be distinguished from M. myrionectae and Z. mobilis on the basis of chemotaxonomic and phenotypic features, including fatty acid composition (particularly C16 : 1ω7c), growth with 6–9 % (w/v) NaCl, carbon utilization, oxidation patterns and so on. A novel species of the genus Maritalea is proposed to accommodate the three isolates, with the name Maritalea porphyrae sp. nov. The type strain is LCM-3T ( = LMG 25872T = NBRC 107169T). Furthermore, it is proposed that Zhangella mobilis should be transferred from the genus Zhangella to the genus Maritalea, with the name Maritalea mobilis comb. nov. (type strain E6T = CGMCC 1.7002T = JCM 15144T).", }
