Yeast Strains Possessing Killer Activity against Candida albicans

Abstract

Strains in various genera and species of yeasts were surveyed for killer activity against Candida albicans. Of 230 strains of the genus Candida, two (C. glabrata TIMM 1062 and C. famata TIMM 1061) had killer activity against C. albicans. Of 36 strains of the genus Hansenula, six showed killer activity against C. albicans. Hansenula anomala TIMM 0705, in particular, exhibited potent killer activity against C. albicans. Of 51 strains of the genus Pichia, 11 had killer activity against C. albicans.
None of seven strains of Cryptococcus neoformans, nine of Saccharomyces cerevisiae, three of Schizosaccharomyces, two of Torulaspora delbrueckii or one of Zygosaccharomyces rouxii had killer activity against any of the tester strains.
