Abstract
A novel alphaproteobacterial strain, designated CPCC 100156(T), was isolated from a forest soil sample collected from Hainan Island, South China, and subjected to taxonomic investigation using a polyphasic approach. The pink- to rosy-coloured colonies on TSA and YM agar were smooth and moist. Good growth occurred at 28-32 °C and at pH 7.0-7.5. The respiratory quinone was ubiquinone-9. The polar lipids consisted of phosphatidylcholine (PC), hydroxyphosphatidylethanolamine (OH-PE), phosphatidylglycerol (PG), diphosphatidylglycerol (DPG) and two unidentified aminolipids (AL1, AL2), with a minor amount of ninhydrin-positive phosphoglycolipid. (NPG). The major cellular fatty acids were summed feature 8 (C(18:1)ω7c /C(18:1)ω6c) (49.5%), summed feature 3 (C(16:1)ω7c/C(16:1)ω6c) (22.5%), and C(16:0) (14.0%). The G+C content of the genomic DNA was 70.3 mol%. The organism showed 16S rRNA gene sequence similarity of 97.37% with Belnapia moabensis DSM 16746(T). Phylogenetic analyses based on 16S rRNA gene sequences showed that the isolate belonged to the family Acetobacteraceae and consistently formed a robust cluster with Belnapia moabensis DSM 16746(T) in the phylogenetic tree. The DNA-DNA hybridization value between the new isolate and Belnapia moabensis DSM 16746(T) was 45.6%. On the basis of the taxonomic evidence, it is proposed that strain CPCC 100156(T) represents a novel species, for which the name Belnapia rosea sp. nov. is proposed. The type strain is CPCC 100156(T) (=DSM 23312(T)=CGMCC 1.10758(T)). The description of the genus Belnapia is emended accordingly.
