Abstract

A facultatively anaerobic bacterium, strain CY01, isolated from subterranean forest sediment collected from Guangdong Province, China, was investigated using a polyphasic taxonomic approach. The cells were short rods, Gram-negative, non-sporulating and motile. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CY01 showed highest sequence similarities to S23 (98.0 %), JCM 5832 (97.9 %), KCTC 12005 (97.7 %) and LMG 23579 (97.0 %). The major respiratory quinone was ubiquinone-8. The major cellular fatty acids were summed feature 3 (Cω6 and/or Cω7), C and summed feature 8 (Cω6 and/or Cω7). Based on the phylogenetic analysis, DNA–DNA hybridization, whole-cell fatty acid composition as well as biochemical characteristics, strain CY01 was clearly distinguishable from all recognized species of the genus and should be classified as a representative of a novel species of the genus, for which the name sp. nov. is proposed. The type strain is CY01 ( = CCTCC AB 2011133 = KACC 16241).
