Abstract:
There is an unresolved debate about the role of magnesium as a regulator of biological functions in the metabolism of yeast, as opposed to the well-known role of calcium. The findings so far assign an increasingly complex and important role to magnesium since its availability in cell culture and fermentation media can influence the growth and metabolism of cells. The reviewed several trials of fermentation with different wine yeasts highlights the important roles played by magnesium and its antagonism with calcium. In this work, we show that the effect of magnesium is dependent strain, acting on the fermentative kinetics and in the production of cellular metabolites. Participating in this way, in a new biotechnological point of view of wine yeasts. Keywords: Role of magnesium, Fermentation, Growth, Metabolites, Wine yeasts.
