Zhang, Boqin published the artcileEffects of mediums on fermentation behaviour and aroma composition in pure and mixed culture of Saccharomyces cerevisiae with Torulaspora delbrueckii, Computed Properties of 111-11-5, the main research area is Saccharomyces cerevisiae Torulaspora delbrueckii culture fermentation behavior aroma composition.
The nutrient status and composition in mediums have a significant effect on yeast metabolism and phenotypic characteristics in wine fermentation In this study, the effects of three frequently used mediums, including synthetic grape juice (SGJ), grape juice without grape pericarp and seeds (GJ) and grape must with grape pericarp and seeds (GMPS), on yeast fermentation behavior and aroma compounds produced by pure and mixed culture of Saccharomyces cerevisiae T73 with Torulaspora delbrueckii TD20 were investigated after alc. fermentation The results showed that high fermentation activities and cell population were always found in GJ medium irresp. of inoculated approach. More esters and higher alcs. were produced in GMPS medium fermented by pure S. cerevisiae, while SGJ medium had increased levels of fatty acids. Consistent with previous literatures, the mixed fermentation of T. delbrueckii and S. cerevisiae produced more acetate esters and fatty acids than the pure culture of S. cerevisiae, while this enol. trait was only found in SGJ and GJ, not in GMPS. Our results highlighted that more attention should be paid to the fermentation medium when evaluating the enol. and aromatic properties of selected yeasts used in industrial winemaking. In this regard, the combined use of GJ and GMPS medium might be a suitable choice.
