Abstract

A Gram-stain-positive, spore-forming, aerobic and filamentous thermoactinomycete, designated GD02, was isolated from soil in south China. The isolate could grow in the presence of 0–3.0 % NaCl (w/v), at temperatures of 30–60 °C and at pH 5.5–9.5, forming ivory-coloured colonies. When the 16S rRNA gene sequence of the isolate was compared with those of other bacteria, the highest similarity was observed with DSM 45196 (96.1 % 16S rRNA gene sequence similarity). The G+C content of the genomic DNA was 56.3 mol%, the cell-wall peptidoglycan contained -diaminopimelic acid, the main polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylmethylethanolamine and phosphatidylglycerol, and the major menaquinone was MK-7. The major cellular fatty acids (>5 %) were iso-C, iso-C, iso-C and anteiso-C. On the basis of its phenotypic and phylogenetic properties, chemotaxonomic analysis and the results of physiological and biochemical tests, strain GD02 ( = CGMCC 1.12404 = KCTC 29149) was designated the type strain of a novel species of the genus , for which the name sp. nov. is proposed.
