Deinococcus aluminii sp. nov., isolated from an automobile air conditioning system

A Gram-stain-positive and pale pink-pigmented bacterial strain, designated ID0501^T, 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 MA1002^T. The major fatty acids of the strain were iso-C_{17: 0}, iso-C_{15: 0} and iso-C_{13: 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 ID0501^T represents a novel species of the genus Deinococcus, for which the name Deinococcus aluminii sp. nov. (=KACC 19286^T =NBRC 112889^T) is proposed.
