Abstract

The plant-pathogen fungus Trichothecium roseum produces in vitro as well as in vivo the toxic metabolites trichothecin, trichothecolone and rosenonolactone. Trichothecin is cytotoxic and inhibits the alcoholic fermentation. It is not metabolized by yeast during the alcoholic fermentation. All toxins showed a minor biological activity against microorganisms other than yeast. Trichothecin caused a bitter taste in wine at higher toxin concentrations (greater than 5 mg/l). Trichothecin was detected in a few samples of wine of higher quality.
