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.

Oak Tannin and Unoaked and Oaked Wine Extracts Influence Gene Expression in HepaRG Human Liver Cells

Previous work from our laboratory has shown that both a purified toasted oak powder and extracts made from unoaked and oaked red wines influenced physiological parameters, metabolism and hepatic gene expression in high-fat fed C57/BL6J male mice (Luo et al., 2020).  Impacted pathways included glucose metabolism, liver fat accumulation, markers of chronic inflammation, and expression of the Gsta1 mRNA.

A novel dataset and deep learning object detection benchmark for grapevine pest surveillance

Flavescence dorée (FD) stands out as a significant grapevine disease with severe implications for vineyards. The American grapevine leafhopper (Scaphoideus titanus) serves as the primary vector, transmitting the pathogen that causes yield losses and elevated costs linked to uprooting and replanting. Another potential vector of FD is the mosaic leafhopper, Orientus ishidae, commonly found in agroecosystems. The current monitoring approach involves periodic human identification of chromotropic traps, a labor-intensive and time-consuming process.
