Comparative studies on the dynamics of fermentation of selected wine yeasts

Abstract

Alcoholic fermentation is an anaerobic biochemical process of oxidation-reduction in which carbohydrates are metabolized by the action of yeast enzymes in major products (ethylalcohol and carbon dioxide) and minor products (superior alcohols, aldehydes, acetic acid, glycerol, volatile acids and others). Typical agents of the alcoholic fermentation are from Saccharomyces genus, by fermentation resulting concentrations in ethylic alcohol higher that 8 alcoholic degrees. In this paper it was studied the dynamics of fermentation of 3 strains of Saccharomyces ellipsoideus wine yeast and were observed parameters such as the accumulation of alcohol, the release of CO2, temperature, amount of oxygen released. It was found that alcoholic fermentation depends on medium factors but also on biotechnological qualities of yeasts selected for this purpose.

The performance of grapevines on identified terroirs in Stellenbosch, South Africa

A terroir can be defined as a natural unit that is characterised by a specific agricultural potential, which is imparted by natural environmental features, and is reflected in the characteristics of the final product.

Vine growing description of Aeolian archipelago

An agroclimatic description of Aeolian archipelago viticulture area (Me), Italy is presented. Aeolian archipelago is located off the northeastern coast of Sicily and it includes the islands of Alicudi, Filicudi, Salina, Panarea, Lipari, Stromboli and Vulcano.

Viticulture and climate: from global to local

Aims: This review aims to (1) present the multiple interests of studying and depicting and climate spatial variability for vitivinicultural terroirs study; (2) explain the factors that affect climate spatial variability according to the spatial scale considered and (3) provide guidelines for climate zoning considering challenges linked to each methodology considered.

Measures to promote biodiversity in viticulture—how do socio-economic factors influence implementation?

Context and purpose. In Germany, vineyards are typically intensively managed monocultural systems shaped by low structural variability.

Effect of the shade generated by simulated solar panels in two row orientation on the physiology and productivity of Vitis vinifera L. cv. Malbec

Context and purpose of the study. In regions where grapevines are grown under irrigation, like most regions in Argentina, the wine industry should adopt more sustainable strategies and production systems towards a higher water use efficiency and a reduction in no-renewable energy consumption.
