Abstract:
:It is known that certain yeast strains, so called 'killers', can produce and excrete proteinaceous toxins that can induce death of other sensitive strains. We obtained a stable fungicidal factor (SKF) through concentration and stabilization of the excretion product of certain killer strains of Saccharomyces cerevisiae (K1 and K2). The isolated proteinaceous complex exhibited activity at broad ranges of pH (4-7.5) and temperatures (20-37.5 degrees C). It was significantly lethal against Candida albicans and Tricophyton mentagrophytes. SKF showed stability and activity after storage, with a mean half-life of 6 months at 4 degrees C or at -20 degrees C.
