Abstract

Bacterial strain LW36 was isolated from activated sludge of a wastewater-treatment bioreactor. Cells of strain LW36 were Gram-negative coccoids to short rods, 1.0–1.2×0.5 μm in size. Colonies were cream-coloured, smooth and circular. Strain LW36 was hetero-organotrophic and chemolithotrophic and was able to use reduced sulfur as an energy resource. Growth was observed at 25–36 °C and pH 5–10. The most abundant cellular fatty acid of strain LW36 was C 7 (64.2 %). The sole respiratory quinone was ubiquinone-10. The G+C content of the genomic DNA was 61.3 mol% ( ). 16S rRNA gene sequence analysis indicated that strain LW36 was phylogenetically related to members of the genus , with similarities ranging from 92.4 to 94.9 %. Based on these results, it is concluded that strain LW36 represents a novel species of the genus , for which the name is proposed. The type strain is strain LW36 (=CGMCC 1.5364=JCM 14013).
