Abstract

Strain CPCC 203383, isolated from the surface-sterilized fruit of (Lindl.) G. Don, was taxonomically characterized based on a polyphasic investigation. It had the highest 16S rRNA gene sequence similarities with DSM 21552 (97.2 %) and DSM 17687 (97.2%). Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain formed a distinct phyletic branch within the genus and the whole genome sequence data analyses supported that strain CPCC 203383 was phylogenetically related to the species. The isolate shared a range of phenotypic patterns reported for members of the genus , but also had a range of cultural, physiological and biochemical characteristics that separated it from related species. The menaquinone was MK-8(H). The polar lipid profile consisted of diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), phosphatidylinositol (PI) and unidentified lipids (ULs). The major fatty acids (>5 %) were -C, -C, -C 9- C, -C and -C. The cell wall peptidoglycan contains -ornithine as diagnostic diamino acid and an interpeptide bridge consisting of -Orn←-Ala←Gly←-Asp. The combined genotypic and phenotypic data indicated that the isolate represents a novel species of the genus for which the name sp. nov. is proposed, with CPCC 203383(=NBRC 113522=KCTC 49200) as the type strain. The DNA G+C composition is 72.3 mol%. The availability of new data allows for an emended description of the genus .
