Mutagen content of wines contaminated with common yeasts

Wines exhibiting a microbial haze were collected and their microbial contents identified. Contaminant yeast species were cultured in grape musts under controlled conditions and extracts of the resultant wines were assayed for mutagen content using four strains of Salmonella in the Ames Salmonella/mi...

Description
Summary:	Wines exhibiting a microbial haze were collected and their microbial contents identified. Contaminant yeast species were cultured in grape musts under controlled conditions and extracts of the resultant wines were assayed for mutagen content using four strains of Salmonella in the Ames Salmonella/microsome/faecalase system. The wine extracts exhibited some toxicity to Salmonella but no mutagen content. It would appear that mutagen content is more a function of the grape species and must preparation than of microbial metabolism during fermentation.
