sp. nov., isolated from an industrial wastewater treatment plant Free

Abstract

The translucent white-coloured, Gram-stain-negative, aerobic, non-motile, fusiform-shaped bacterium (designated strain SY72) 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 of the class . Strain SY72 is closely related to KCTC 23724 (97.8 % 16S rRNA gene sequence similarity) and DC2N1-10 (96.4 %), respectively. DNA–DNA relatedness between strain SY72 and the closest phylogenetically related strain, KCTC 23724, was 18.0±0.7 %. In strain SY72, the predominant respiratory quinone was ubiquinone Q-10, and the cellular fatty acids consisted mainly of Cω7 and Cω7-11 methyl. The major polar lipids were phosphatidylcholine, phosphatidylglycerol, diphosphatidylglycerol and phosphatidylethanolamine. Photoautotrophic and photoheterotrophic growth did not occur in strain SY72. Furthermore, strain SY72 did not produce photosynthetic pigments or contain the photosynthetic genes and , by which it differed from the phototrophic species of the family . On the basis of distinct phenotypic and phylogenetic properties, strain SY72 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is SY72 (=KCTC 62105=NBRC 113021).
