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.

Effects of different organic amendments on soil, vine, grape and wine, in a long-term field experiment in Chinon vineyard (France)

In a long-term experiment carried out in Chinon vineyard (37, France) during 23 years, the effects of several organic amendments were studied on soil, vine, grapes and wine. Four main treatments were compared on a calcareous sandy soil: control without organic amendment, dry crushed pruning wood at 2.1.t-1.ha-1.year-1 (D1), cow manure at 10 t-1. ha-1.year-1 (D1) and cow manure applied at 20 t-1.ha-1.year-1 (D2). D1 levels were calculated to fill the annual humus losses by mineralization.

Analysis of volatile composition of interaction between the pathogen E. necator and two grapevine varieties

Volatile organic compounds (VOCs) are emitted by nearly all plant organs of the plants, including leaves. They play a key role in the communication with other organisms, therefore they are involved in plant defence against phytopathogens. In this study VOCs from grapevine leaves of two varieties of Vitis vinifera infected by Erysiphe necator were analysed. The varieties were selected based on their susceptibility to pathogen, Kishmish Vatkana has the Ren1 resistance gene and Zamarrica showed high susceptibility in previous trials.
