Abstract

Abstract : A white-coloured, Gram-stain-negative, aerobic, rod-shaped bacterium (designated strain SY21 T ) 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 T exhibited 16S rRNA gene sequence similarities of 95.5–98.0 % to Thermomonas species and clustered with the type species of the genus Thermomonas . In strain SY21 T, the predominant respiratory quinone was ubiquinone Q-8, and the cellular fatty acids consisted mainly of iso-C15 : 0, C16 : 0, iso-C11 : 0 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 T and the closest phylogenetically related strain, Thermomonas carbonis KCTC 42013 T, was 35.0±0.1 %. Based on the distinct phenotypic, chemotaxonomic and phylogenetic properties, strain SY21 T represents a novel species of the genus Thermomonas, for which the name Thermomonas aquatica sp. nov. is proposed. The type strain is SY21 T (=KCTC 62191 T =NBRC 113114 T ).
