| Abstract: | Killer strains of the genera Saccharomyces, Hansenula and Kluyveromyces were tested for killing activity against yeasts that cause trouble in the food industry (in the genera Zygosaccharomyces, Kloeckera, Saccharomycodes and Schizosaccharomyces). Saccharomyces strains killed only Zygosaccharomyces rouxii strains, while non-Saccharomyces strains showed a wider anti-yeast spectrum. The Kluyveromyces phaffii killer strain was of particular interest because of its killer action against Kloeckera apiculata, Saccharomycodes ludwigii and Zygosaccharomyces rouxii. |
