Pietrafesa, Angela published the artcileSaccharomyces cerevisiae and Hanseniaspora uvarum mixed starter cultures: Influence of microbial/physical interactions on wine characteristics, Synthetic Route of 106-32-1, the main research area is Saccharomyces Hanseniaspora wine carbon dioxide phenylethyl acetate; Hanseniaspora uvarum; Saccharomyces cerevisiae; cell-to-cell contact; wine composition.
The growing trend in the wine industry is the revaluation of the role of non-Saccharomyces yeasts, promoting the use of these yeasts in association with Saccharomyces cerevisiae. Non-Saccharomyces yeasts contribute to improve wine complexity and organoleptic composition However, the use of mixed starters needs to better understand the effect of the interaction between these species during alc. fermentation The aim of this study is to evaluate the influence of mixed starter cultures, composed by combination of different S. cerevisiae and Hanseniaspora uvarum strains, on wine characteristics and to investigate the role of cell-to-cell contact on the metabolites produced during alc. fermentation In the first step, three H. uvarum and two S. cerevisiae strains, previously selected, were tested during mixed fermentations in natural red grape must in order to evaluate yeast population dynamics during inoculated fermentation and influence of mixed starter cultures on wine quality. Our results revealed that phys. contact between S. cerevisiae and H. uvarum affected the viability of H. uvarum strain, influencing also the metabolic behavior of the strains. Although different researches are available on the role of cell-to-cell contact-mediated interactions on cell viability of the strains included in the mixed starter, to our knowledge, very few studies have evaluated the influence of cell-to-cell contact on the chem. characteristics of wine.
