- Abstract
A Gram-staining negative bacterium, designated as GSS15T, was isolated from compost in Guangzhou, China. Cells of strain GSS15T were rod-shaped and non-motile. The isolate was able to grow at 15–42 °C (optimum 30 °C) and pH 6.0–11.0 (optimum pH 8.0), and tolerate up to 6.0% NaCl (w/v). When the 16S rRNA gene sequence of the isolate was compared with those of other bacteria, the highest similarity was observed with Pseudoxanthomonas helianthi roo10T (96.9%). Furthermore, strain GSS15T showed low ANI (75.7–79.5%) and DDH (24.2–18.3%) values to the closely related species. Q-8 was the predominant respiratory quinone. The major cellular fatty acids (> 5%) were iso-C15:0 (18.7%), C16:1ω7c (18.6%), anteiso-C15:0 (13.2%), C16:0 (9.8%), and iso-C16:0 (8.8%). The polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol, and diphosphatidylglycerol. Based on its phenotypic, chemotaxonomic and genotypic data, strain GSS15T (= KCTC 52974T = MCCC 1K03334T) is designated as the type strain of a novel species of the genus Pseudoxanthomonas, for which the name Pseudoxanthomonas composti sp. nov. is proposed.
