“…The members of this significant group are highly related and appear clearly separated from the other Kluyveromyces species. This is consistent with the ability of these strains to mate in the laboratory (Johannsen, 1980) and with the results of DNA base composition and relatedness (Fuson et al, 1987 ;Vaughan-Martini & Martini, 1987), isoenzyme analysis (Sidenberg & Lachance, 1983 and karyotyping (Sor & Fukuhara, 1989 ;Viljoen et al, 1989), although there is evidence of heterogeneity in these species at the intraspecific level (Cottrell et al, 1987 ;Belloch et al, 1997 ;Lehmann et al, 1992 ;Molnar et al, 1996). A second group includes the species K. africanus, Kluyveromyces delphensis, Kluyveromyces lodderae, K. polysporus and Kluyveromyces yarrowii, which appear intermixed with species belonging to the genera Saccharomyces, Torulaspora and Zygosaccharomyces in a polyphyletic group.…”

A phylogenetic analysis of 17 species belonging to the genus Kluyveromyces and 12 reference and outgroup species was performed using mitochondrial cytochrome-c oxidase II gene sequences. The genus Kluyveromyces appears as a polyphyletic taxon formed by species included within the following four main groups. The Kluyveromyces phaffii group encompasses the species Kluyveromyces blattae, K. phaffii and Kluyveromyces yarrowii. The Kluyveromyces marxianus group is a monophyletic group consisting of the species Kluyveromyces aestuarii, Kluyveromyces dobzhanskii, Kluyveromyces lactis, K. marxianus and Kluyveromyces wickerhamii. The monophyletic Kluyveromyces thermotolerans group is formed by K. thermotolerans, Kluyveromyces waltii and Saccharomyces kluyveri (which appears in the mitochondrial tree as the sister clade of the K. marxianus group). Finally, the Saccharomyces cerevisiae group contains the remaining Kluyveromyces species, as well as the reference Saccharomyces species (sensu lato and sensu stricto) and Candida glabrata (the phylogenetic relationships within this group are unclear according to the bootstrap test). The phylogenetic relationships obtained for this mitochondrial gene are, for the most part, congruent with previous trees based on nuclear rRNA sequences, except for the position of K. yarrowii and the close relationship between the K. marxianus and K. thermotolerans groups. These differences, as well as the existence of these groups, are discussed in the context of previous studies based on phenotypic, genetic and molecular data. Although additional studies are required to decipher the phylogenetic relationships between the genus Kluyveromyces and the closely related genera Saccharomyces, Torulaspora and Zygosaccharomyces, future changes to their taxonomic status should take account of the existence of these four groups of Kluyveromyces species.

“…However, the first attempt to associate lipid composition with taxonomic classification was made by Abel et al (1963), who illustrated that qualitative fatty acid analyses were useful for distinguishing between heterogeneous bacteria. Primary fatty acids, ranging from C14 to C20, have been detected in ascomycetous yeasts and have been used in the classification and identification of these organisms (Cottrell et al, 1985;Kock et al, 1986;Viljoen et al, 1986) as well as for the basidiomycetous yeasts (Smit et al, 1987a, 6 ; van der Westhuizen et al, 1987a, 6).…”

The cellular long-chain fatty acids present in 33 strains, representing 15 species of Cryptococcus, and 4 species of Tremella, were determined by gas chromatography. According to the relative amounts of fatty acid methyl esters, the Cryptococcus species studied were divided into four main groups. Possible relationships between species representing the two genera are presented in a new model, where cellular long-chain fatty acid compositions and other phenotypic characteristics are included.
