A Gram positive, aerobic, non-motile, coccoid, arsenic-resistant actinobacterial strain designated as CM1E1T was isolated from the lateral root tissue of Prosopis laegivata grown on a mine tailing in San Luis Potosi, Mexico. Phylogenetic analysis based on 16S rRNA genes revealed that strain CM1E1T was clustered closely with Kocuria species, showing the highest sequence similarity of 98.7 % to Kocuria rhizophila TA68T. The DNA G + C content of strain CM1E1T was 74.5 mol% (Tm). The major fatty acids were anteiso-C15:0, anteiso-C17:0 and iso-C15:0. The peptidoglycan of cell wall contained lysine and alanine. The major respiratory quinones were MK-7 (H2) and MK-8 (H2). On the basis of the phenotypic characterization, phylogenetic relation and chemotaxonomic analyses, strain CM1E1T (=CCBAU 101092T=HAMBI 3625T =LMG 8671T) represents a novel species in genus Kocuria, for which the name Kocuria arsenatis sp. nov is proposed.
