title: Utilisation of differential killer toxin sensitivity patterns for fingerprinting and clustering yeast strains belonging to different genera.
abstract: The differential killer sensitivity of 103 yeast cultures belonging to 12 species (genera Debaryomyces, Kluyveromyces, Saccharomyces, and Zygosaccharomyces), all previously taxonomically certified by nDNA-nDNA reassociation, against a given panel of 39 killer yeasts was used as a fingerprinting tool. All strains, with the only exception of eight cultures belonging to the species Zygosaccharomyces bailii, were characterised by a specific, individual sensitivity pattern (killer formula). Cluster analysis of binary sequences based on killer sensitivity of strains belonging to different genera is presented and discussed.
