A motile, rod-shaped, yellow-pigmented bacterium, designated strain CW1(T), was isolated from a water-cooling system in the Republic of Korea. Cells were Gram-stain-positive, aerobic, catalase-positive and oxidase-negative. Strain CW1(T) formed slender rods with unusual bulbous protuberances. The major fatty acids iso-C(16 : 1) (33.7 %), anteiso-C(15 0) (27.2 iso-C(14 (13.3 %) C(16 (10.8 %). cell-wall peptidoglycan type B2beta, containing lysine as diamino acid. respiratory quinones menaquinones 12, 13 14 isoprene units. phylogenetic tree based on 16S rRNA gene sequences showed that an evolutionary lineage within radiation enclosing members family Microbacteriaceae related to, but distant from, genera Microcella Yonghaparkia. On basis evidence presented, is considered to represent novel species new genus Microbacteriaceae, for which name Chryseoglobus frigidaquae gen. nov., sp. nov. proposed.
