摘要

An aerobic, non-motile and Gram-staining-positive bacterial strain (1PNM-19(T)) 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(T) was affiliated to the genus Deinococcus and most closely related to Deinococcus aquatilis DSM 23025(T) and Deinococcus ficus DSM 19119(T). The major respiratory quinone was determined to be menaquinone 8 (MK-8) and the major fatty acids contained summed feature 3 (C-16:1 omega 7c and/or C-16:1 omega 6c) and C-16:0. 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(T) was 71.7 +/- 0.1 mol%. Based on data from this taxonomic study, strain 1PNM-19(T) represents a novel species of the genus Deinococcus, for which the name Deinococcus metalli sp. nov. is proposed. The type strain is 1PNM-19(T) (=GIMCC 1.654(T)=CCTCC AB 2014198(T)=DSM 27521(T)).
