Strains SW-117T and SW-120T simultaneously contained both menaquinones (MK) and ubiquinones (Q) as isoprenoid quinones; the predominant menaquinone was MK-7 and the predominant ubiquinones were Q-7 and Q-8. The major fatty acid detected in the two strains was iso-C15 : 0. The DNA G+C content of strains SW-117T and SW-120T was 51 and 54 mol%, respectively. Phylogenetic analyses based on 16S rRNA gene sequences showed that strains SW-117T and SW-120T fall within the radiation of the cluster comprising Shewanella species. Strains SW-117T and SW-120T showed a 16S rRNA gene sequence similarity of 97·4 % and a DNA–DNA relatedness level of 10·1 %. Strains SW-117T and SW-120T exhibited 16S rRNA gene sequence similarity levels of 93·8–98·5 % and 92·4–97·0 %, respectively, to Shewanella species. Strain SW-117T exhibited DNA–DNA relatedness levels of 8·3–20·3 % to the type strains of six phylogenetically related Shewanella species. On the basis of phenotypic, phylogenetic and genetic data, strains SW-117T and SW-120T were classified in the genus Shewanella as two distinct novel species, for which the names Shewanella marisflavi sp. nov. (type strain, SW-117T=KCCM 41822T=JCM 12192T) and Shewanella aquimarina sp. nov. (type strain, SW-120T=KCCM 41821T=JCM 12193T) are proposed, respectively. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.63198-0
