Mathematical models of the dynamics of fermentation of wine yeasts under the influence of vitamins

Abstract

Biomass accumulation in yeast has been studied in this work in terms of their role in fermentation processes. So, biotin is involved in many reactions and nitrogen metabolism disorders, in protein biosynthesis and fatty acid synthesis. It is known that yeast cell is not capable to synthesize biotin, but it presence in the environment is unconditionally linked to production cost. Requirement for biotin yeast partially reduced in the presence of amino dicarboxylic environment. Effectiveness is increased under conditions of intense aeration, ascertaining the best results when additives order thousandths per liter of fermentation under anaerobic conditions (Banu, 2008, 2009).
Inositol (vitamin B9) is a derivative of cyclohexane polyol, which participate in lipid synthesis and especially phosphoglycerides.
Comparative studies have demonstrated their good role in fermentation processes and in particular to obtain yeast biomass with higher quality biotech.

The importance of landscape in wine quality perception: l’importanza del paesaggio nella percezione qualitativa del vino

The wine quality is a characteristic that is both difficult to define and communicate, because the quality attributes can be divided into intrinsic (objective, such as alcohol degree, acidity

How to deal with the Green Deal – Resistant grapevine varieties to reduce the use of pesticides in the EU

With its Farm-to-Fork Strategy, which is a part of the European Green Deal, the European Union aims at reducing the amount of pesticides used in agriculture by 50% until 2030. As viticulture uses around 70% of the fungicides in the EU, there is substantial pressure on winemakers to reduce their pesticide input. On top of the political goal, winegrowers face increased pressure from the public demanding a more sustainable production of wine.

Developmental and genetic mechanisms underlying seedlessness in grapevine somatic variants

Seedless table grapes are greatly appreciated for fresh and dry consumption. There is also some interest in seedless winegrapes, because the combination of lower fruit set, smaller berries with higher skin/pulp ratio and looser bunches with the absence of seeds in crushed berries, a possible source of astringent tannins, might also have favorable effects on wine quality.
