“…Since we did not employ D. subglobosus HUT 7240, which they employed as the standard strain for antigenic analysis, further investigation is necessary in this respect. Our result coincided with that of TsUCHIYA et al (3)(4)(5)(6) in the difference of D. hansenii-T, famata and T, candida. We found, however, that D. hansenii-T, famata had specific antigen which was not detected in T. candida (Table 6).…”

“…In the present study, we could not confirm the results of TsUCHIYA et al (4,5) who reported that T. candida and D. subglobosus had specific antigen 33 in addition to the antigens common to D, hansenii, D. kloeckeri, D, nicotianae, and T. famata. Since we did not employ D. subglobosus HUT 7240, which they employed as the standard strain for antigenic analysis, further investigation is necessary in this respect.…”

“…Therefore, KREGER-VAN RIJ (7,20) combined these 4 species into a single species, D. hansenii. On the other hand, TsUCHIYA et al (3)(4)(5)(6) found that these Debaryomyces yeasts can be divided into 2 groups on the basis of serological characteristics. Namely, D, hansenii, D, kloeckeri, and D, nicotianae have thermostable surface antigens 1, 4, 9, 2, 3, 14 while D. subglobosus has specific antigen 33 in addition to the antigens common to the former species.…”

“…According to them, Torulopsis famata is the imperfect form of D. kloeckeri. Later, TsUCHIYA and coworkers (3)(4)(5)(6) classified these yeasts into 2 species, D. hansenii and D. subglobosus, on the basis of antigenic analysis using cell agglutination techniques. They considered that T. famata was the imperfect form of the former species and Torulopsis candida was that of the latter species.…”

Taxonomic studies on Debaryomyces hansenii (ZOPF) Lodder et Kregervan Rij and related yeast species were carried out using chemotaxonomic methods including DNA base composition, DNA-DNA hybridization, ubiquinone system, proton magnetic resonance spectrum of mannan, and serological methods. The 50 strains employed were classified into 3 groups, I, II, and III, based on DNA-DNA hybridization experiments. These groups were considered to represent three distinct species. Group I consisted of two subgroups, Ia and Ib, which were considered to represent two distinct varieties. These groups were also characterized by proton magnetic resonance spectra of alkali-extracted mannans and cell surface antigens, however, they could not be discriminated by DNA base composition and ubiquinone systems, in addition to the taxonomic criteria commonly employed in yeast taxonomy. Group Ia comprised 34 strains including the type or authentic strains of D.
