Strain FSX-11T showed less than 96.5 % 16S rRNA gene sequence similarity to the type strains of species with validly published names. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the novel isolate formed a distinct monophyletic clade within the family Rhodobacteriaceae and clustered distantly with the genera Thalassobius and Marivita . Cells of strain FSX-11T were non-motile, oval-shaped and facultative anaerobic. Optimal growth occurred at 20–30 °C, at pH 7.0–8.0 and in the presence of 2–3 % NaCl (w/v). The major respiratory quinone was ubiquinone-10. Summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c), 11-methyl C18 : 1ω7c and C16 : 0 were the major fatty acids. The DNA G+C content of strain FSX-11T was 58.7 mol%. On the basis of phylogenetic analysis, phenotypic and chemotaxonomic characteristics and 16S rRNA gene signature nucleotide patterns, strain FSX-11T represents a novel species in a novel genus within the family Rhodobacteraceae , for which the name Litorivita pollutaquae gen. nov., sp. nov. is proposed. The type strain is FSX-11T (=JCM 32715T=MCCC 1K03503T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.003084
