Previously, we reported that thin-layer chromatography of ethyl ether-ethanol extracts of mycobacteria after incubation with 35S-methionine was useful for differentiation among mycobacterial species (Tsukamura, M. & Mizuno, S.: Int. J. Syst. Bacteriol., 25: 271-280, 1975; Kekkaku, 53: 85-89, 1978; Kekkaku, 54: 15-27, 1979). The method was also useful for differentiating rhodococci from nocardiae (Tsukamura, M. & Mizuno, S.: J. Gen. Microbiol., 105: 159-160, 1978). In the present study, the meaning of petroleum ether-soluble fraction has been studied, restricting the subject to this fraction.
