Abstract

A Gram-stain-negative, non-motile bacterial strain designated 1NM-4 was isolated from an abandoned lead–zinc ore mine site in Mei County, Meizhou, Guangdong Province, southern China. The isolate was light yellow, strictly aerobic, oxidase-negative and catalase-positive. Phylogenetic analyses based on 16S rRNA, and gene sequences, together with DNA–DNA hybridization values less than 70 %, revealed that strain 1NM-4 belongs to the genus and may represent a novel species. The major respiratory quinone was ubiquinone 9 (Q-9) and the major cellular fatty acids consisted of Cω9, summed feature 3 (Cω7 and/or Cω6), C and C. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, an unidentified aminolipid and two unidentified phospholipids. The genomic DNA G+C content of strain 1NM-4 was 47.17±0.02 mol%. Based on phenotypic, phylogenetic and chemotaxonomic characteristics, strain 1NM-4 should be assigned to a novel species of the genus , for which the name sp. nov. is proposed. The type strain is 1NM-4 ( = GIMCC 1.656 = CCTCC AB 2014199 = KCTC 42012).
