Arenimonas metalli sp. nov., isolated from an iron mine

A Gram-staining-negative, aerobic, rod-shaped bacterium (CF5-1T ) was isolated from Hongshan Iron Mine, Daye City, Hubei province, China. The major cellular fatty acids (.10 %) were isoC16 : 0, iso-C15 : 0, C16 : 1v7c alcohol and iso-C17 : 1v9c. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The major respiratory quinone was Q-8. The genomic DNA G+C content was 70.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CF5-1T was most closely related to Arenimonas malthae (95.3 % gene sequence similarity), Arenimonas oryziterrae (94.7 %), Arenimonas donghaensis (94.6 %) and Arenimonas composti (94.5 %). A taxonomic study using a polyphasic approach showed that strain CF5-1T represents a novel species of the genus Arenimonas, for which the name Arenimonas metalli sp. nov. is proposed. The type strain is CF5-1T (5CGMCC 1.10787T 5KCTC 23460T 5CCTCC AB 2010449T ).
