Abstract

A novel Gram-stain-negative strain, WQ 117, isolated from the faeces of collected at Yunnan Snub-nosed Monkey National Park, Yunnan province, PR China, was subjected to a polyphasic taxonomic study. The results of phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate represented a member of the genus , sharing 97.64 % sequence similarity with the type strain YIM 102668. The G+C content of the genomic DNA of WQ117 was 30.5 mol%. The predominant isoprenoid quinone was MK-6. The major cellular fatty acids was iso-C. The whole genome average nucleotide identity (gANI) values and the digital DNA–DNA hybridization values between WQ 117 and YIM 102668 were 79.66 % and 22.20 %, respectively. Growth occurred at 0–50 °C (optimally at 28–35 °C), pH 7.0–9.0 (optimally at pH 8.0) and with 0–2 % (w/v) NaCl (optimally without NaCl). On the basis of the taxonomic evidence, a novel species, sp. nov., is proposed. The type strain is WQ 117 (=KCTC 82394=CCTCC AA 2020027).
