On the metabolism of sulphate and sulphite during the fermentation of grape must by Saccharomyces cerevisiae

Abstract

1. Using labelled sulphate (35S) and sulphite (35S) it is demonstrated that one normal (WE I) and two so-called SO2-forming (729 and Mumm) strains of Saccharomyces cerevisiae form H2S from both sulphate and sulphite during fermentation of grape must. 2. Addition of methionine and cysteine almost completely suppresses sulphite und sulphide formation from… (More)
