Abstract

An aerobic, non-motile and Gram-staining-positive bacterial strain (1PNM-19) was isolated from a lead-zinc ore in an abandoned mine and was investigated in a taxonomic study using a polyphasic approach. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain 1PNM-19 was affiliated to the genus and most closely related to DSM 23025 and DSM 19119. The major respiratory quinone was determined to be menaquinone 8 (MK-8) and the major fatty acids contained summed feature 3 (Cω7 and/or Cω6) and C. A complex polar lipid profile consisted of different unidentified glycolipids and polar lipids, two unidentified aminolipids, an unidentified phosphoglycolipid, phospholipid and aminophospholipid. The genomic DNA G+C content of strain 1PNM-19 was 71.7 ± 0.1 mol%. Based on data from this taxonomic study, strain 1PNM-19 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is 1PNM-19 ( = GIMCC 1.654 = CCTCC AB 2014198 = DSM 27521).
