Transfer of Rhodococcus aichiensis Tsukamura 1982 and Nocardia amarae Lechevalier and Lechevalier 1974 to the genus Gordona as Gordona aichiensis comb. nov. and Gordona amarae comb. nov

Int J Syst Bacteriol. 1994 Oct;44(4):769-73. doi: 10.1099/00207713-44-4-769.


We investigated the taxonomic status of Rhodococcus aichiensis DSM 43978T (T = type strain) and Nocardia amarae DSM 43392T by using both chemotaxonomic and genetic methods. The occurrence of MK-9(H2) as the predominant menaquinone, the presence of relatively long-chain mycolic acids (48 to 62 carbon atoms), and the phylogenetic position as determined by a 16S ribosomal DNA sequence analysis provide strong evidence that both R. aichiensis and N. amarae should be transferred to the genus Gordona as Gordona aichiensis and Gordona amarae, respectively.
