Abstract

The genus was proposed by Tsukamura in 1971 (M. Tsukamura, J. Gen. Microbiol. 68:15-24,1971) and was revived in 1988 by Stackebrandt et al. (E. Stackebrandt, J. Smida, and M. D. Collins, J. Gen. Appl. Microbiol. 34:341-348, 1988) to accommodate species containing mycolic acids with 48 to 66 carbon atoms and MK-9(H) as the predominant menaquinone type. On the basis of mycolic acid composition as determined by high-performance liquid chromatography, DNA-DNA similarity data (S1 nuclease procedure), and the rRNA gene restriction patterns of the type strains, we propose that Tsukamura 1982 is a subjective synonym of (Tsukamura 1978) Stackebrandt 1989 comb. nov. We found that type strain ATCC 33609, and type strain ATCC 29627 exhibit identical mycolic acid profiles, 97% DNA relatedness (difference in thermal denaturation midpoints, 1.0°C), and similar ribotypes after II endonuclease digestion. Thus, as defined by the type strains and considering the priority of the name , these two species should be regarded as a single species named ; an emended description of this taxon is given.
