Abstract

An aerobic, chemoheterotrophic, non-motile, capsule-forming bacterium designated DHOF10 was isolated from a soil sample collected from the forest of Dinghushan Biosphere Reserve, Guangdong Province, PR China. Strain DHOF10 was able to grow at pH 3.5–8.0 (optimum pH 4.0–4.5) and at 10–37 °C (optimum 28–37 °C). NaCl tolerance was up to 1.0 % (w/v). Major fatty acids consisted of iso-C, Cω9 and Cω7. The quinone was MK-8 and the DNA G+C content was 56.3 mol%. The polar lipids consisted of phosphatidylethanolamine, an unidentified aminolipid, an unidentified phospholipid, two unidentified aminophospholipids and two unidentified polar lipids. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolate was a member of genus of the phylum , with the highest 16S rRNA gene sequence similarity of 97.3 % to AP8. On the basis of phylogenetic, phenotypic, physiological and chemotaxonomic distinctiveness, strain DHOF10 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is DHOF10 ( = CGMCC 1.13007 = KCTC 42631).
