The translucent white-coloured, Gram-stain-negative, aerobic, non-motile, fusiform-shaped bacterium (designated strain SY72T) was isolated from waste-activated sludge. Optimal growth occurred at 30-37 °C and pH 6.0-7.0. Phylogenetic analysis based on the 16S rRNA gene sequences revealed that the novel isolate belonged to the family Rhodobacteraceae of the class Alphaproteobacteria. Strain SY72T is closely related to Tabrizicola aquatica KCTC 23724T (97.8% 16S rRNA gene sequence similarity) and Pseudorhodobacter aquaticus DC2N1-10T (96.4%), respectively. DNA-DNA relatedness between strain SY72T and the closest phylogenetically related strain, Tabrizicola aquatica KCTC 23724T, was 18.0±0.7%. In strain SY72T, the predominant respiratory quinone was ubiquinone Q-10, and the cellular fatty acids consisted mainly of C18:1ω7c and C18:1ω7c-11 methyl. The major polar lipids were phosphatidylcholine, phosphatidylglycerol, diphosphatidylglycerol and phosphatidylethanolamine. Photoautotrophic and photoheterotrophic growth did not occur in strain SY72T. Furthermore, strain SY72T did not produce photosynthetic pigments or contain the photosynthetic genes pufL and pufM, by which it differed from the phototrophic species of the family Rhodobacteraceae. On the basis of distinct phenotypic and phylogenetic properties, strain SY72T represents a novel species of the genus Tabrizicola, for which the name Tabrizicola fusiformis sp. nov. is proposed. The type strain is SY72T (=KCTC 62105T=NBRC 113021T)
