A Gram-stain-positive and pale pink-pigmented bacterial strain, designated ID0501T, was isolated from an automobile evaporator core collected in the Republic of Korea. The cells were aerobic and coccoidal. The strain grew at 15–40 ˚C (optimum, 37 ˚C), at pH 6.0–7.0 (optimum, pH 6.5), and in the presence of 0–1.5 % (w/v) NaCl. Phylogenetically, the strain was related to members of the genus Deinococcus and showed the highest sequence similarity, of 96.9 %, with Deinococcus metallilatus MA1002T. The major fatty acids of the strain were iso-C17 : 0, iso-C15 : 0 and iso-C13 : 0. The predominant respiratory quinone was MK-8. The polar lipids profile revealed the presence of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, diphosphatidylglycerol, unidentified phospholipids, an unidentified aminolipid and unidentified glycolipids. The DNA G+C content of the strain was 68.3 mol%. On the basis of phenotypic, genotypic and chemotaxonomic data, strain ID0501T represents a novel species of the genus Deinococcus , for which the name Deinococcus aluminii sp. nov. (=KACC 19286T=NBRC 112889T) is proposed.
