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

Abstract

A white-coloured, Gram-stain-negative, aerobic, rod-shaped bacterium (designated strain SY21) was isolated from waste-activated sludge. Optimal growth occurred at 28 °C and pH 7.0. Phylogenetic analysis based on the 16S rRNA gene sequences showed that strain SY21 exhibited 16S rRNA gene sequence similarities of 95.5–98.0 % to species and clustered with the type species of the genus . In strain SY21, the predominant respiratory quinone was ubiquinone Q-8, and the cellular fatty acids consisted mainly of iso-C, C, iso-C 3-OH, summed feature 3 and summed feature 9. The major polar lipids were phosphatidylcholine, phosphatidylglycerol and phosphatidylethanolamine. The genomic DNA G+C content was determined to be 67.9 mol% and the DNA–DNA relatedness between strain SY21 and the closest phylogenetically related strain, KCTC 42013, was 35.0±0.1 %. Based on the distinct phenotypic, chemotaxonomic and phylogenetic properties, strain SY21 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is SY21 (=KCTC 62191=NBRC 113114).
