Three new species in the Saccharomyces sensu stricto complex: Saccharomyces cariocanus, Saccharomyces kudriavzevii and Saccharomyces mikatae

Int J Syst Evol Microbiol. 2000 Sep;50 Pt 5:1931-1942. doi: 10.1099/00207713-50-5-1931.

Abstract

On the basis of genetic analysis, molecular karyotyping and sequence analyses of the 18S rRNA and internal transcribed spacer (ITS) region, three new Saccharomyces species are described, Saccharomyces cariocanus (with type strain NCYC 2890T), Saccharomyces kudriavzevii (with type strain NCYC 2889T) and Saccharomyces mikatae (with type strain NCYC 2888T). Genetic and molecular analyses did not confirm the previously observed conspecificity of Saccharomyces paradoxus and S. cariocanus. The latter species exhibits postzygotic isolation from representative strains from all known geographical populations of S. paradoxus: European, Far-East Asian, North American and Hawaiian.
