Abstract

Tese de Doutoramento em Biologia Ambiental e MolecularWine flavour and aroma are the result of yeast metabolism and must compounds interactions. During must fermentation thousands of volatile aroma compounds are formed, with higher alcohols, acetate esters and ethyl esters being the main aromatic compounds contributing to a floral and fruity aroma. The action of yeast, in particular of Saccharomyces cerevisiae strains, on the must components will build the architecture of the wine flavour and their fermentation bouquet. Only a holistic approach based on systems biology, an inter-disciplinary area combining the study of biology, chemistry, physics and mathematics, based on data-driven and model-based elucidation of complex biological...
