Isolation of a WildCandidaKiller Yeast with a Novel Killer Property

Abstract
A killer yeast designated strain SW-55, isolated from the skin of grape berries, had killer activity of a novel type. Taxonomic studies revealed that the killer strain belonged to the genus Candida. The killer activity had a broad optimum pH range, high thermal and pH stabilities, and broad anti-yeast spectra. The SW-55 killer character may be encoded by chromosomal genes, not by extrachromosomal ones.
