Tsukamura M,
( 1982 ) Numerical analysis of the taxonomy of Nocardiae and Rhodococci. PMID : 6763136 DOI : 10.1111/j.1348-0421.1982.tb00260.x Abstract >>
The genera Nocardia and Rhodococcus were clearly differentiated in the present study. Eleven characteristics were shown to be useful for differentiation between these two genera. Nocardia asteroides sunsu stricto previously defined by Tsukamura was divided into two taxa. One contained the type strain and was considered to retain the name Nocardia asteroides in a new sense. Another was named in the present study as Nocardia nova sp. nov. Tsukamura. The type strain of this species is ATCC 33726. The following seven characters were useful for differentiating N. nova from newly defined N. asteroides: 1) arylsulfatase activity after 14 days; 2) catalase activity (semiquantitative); 3) beta-esterase activity; 4) pyrazinamidase activity; 5) utilization of citrate as a sole source of carbon; 6) utilization of 2,3-butylene glycol as a sole carbon source; and 7) resistance to 5-fluorouracil (20 micrograms/ml). The name Nocardia farcinica for Tsukamura's Kyoto-I group should be rejected. This taxon has been named Nocardia paratuberculosis sp. nov. Tsukamura. The type strain is ATCC 23826. Three new species of the genus Rhodococcus were proposed: Rhodococcus aichiensis sp. nov. Tsukamura (type strain, ATCC 33611); Rhodococcus chubuensis sp. nov. Tsukamura (type strain, ATCC 33609); Rhodococcus obuensis sp. nov. Tsukamura (type strain, ATCC 33610).

( 2001 ) A taxonomic note on the authorship and date of valid publication of Rhodococcus sputi. PMID : 11211266 DOI : 10.1099/00207713-51-1-255 Abstract >>
Authorship of the name Rhodococcus sputi is variously attributed to Tsukamura 1978 or Tsukamura and Yano 1985. DNA-DNA binding data indicate that this species and Rhodococcus obuensis Tsukamura 1983 and Rhodococcus chubuensis Tsukamura 1983 are subjective (heterotypic) synonyms. Although these organisms have been placed in the genus Gordonia as Gordonia sputi, the correct name of the taxon created by unification of these three species is directly affected by the date of valid publication of these species as members of the genus Rhodococcus. Thus, the name R. sputi only has priority if the authorship is attributed to Tsukamura 1978. The question of authorship and priority is clarified in the present work.

( 1988 ) DNA base composition and homology values in the classification of some Rhodococcus species. PMID : 3254937 DOI : 10.1099/00221287-134-10-2807 Abstract >>
Similar DNA homology values were recorded when a modified S1 nuclease technique and a standard nitrocellulose membrane filter method were applied to representative strains of Rhodococcus. The DNA homology data showed that R. globerulus, R. luteus and R. sputi form distinct genomic species. The congruence between the DNA homology and earlier numerical phenetic data was good, but there was evidence that some strains had been misclassified in the previous studies. In particular, the type strains of R. obuensis and R. sputi belong to a single genomic species. The former name is thus a later, subjective synonym of the latter. The guanine plus cytosine content of the DNA of the rhodococci fell within the range 61 to 72 mol%.
