[Identification of Zygowillopsis californica strains of various origin by polymerase chain reaction with universal primers].

After reevaluation of the taxonomic position of 27 yeast collection strains of different origin by UP-PCR followed by dot-hybridization, only 22 strains were assigned to the biological species Zygowilliopsis californica (Lodder) Kudriavzev. Four strains were identified as Williopsis suaveolens (Klöcker) Naumov et al. Universal primers L45 and N21 are recommended for identification of the Z. californica yeasts.
