Figure 3From: Genetic manipulation of longevity-related genes as a tool to regulate yeast life span and metabolite production during winemakingSuperoxide dismutase 2 overexpression has a mild impact on life span. The SOD2-overexpressing strain and its parental strain L2056 were used to inoculate natural grape juice fermentations. Cell viability over time was measured as cfu/mL and fermentation evolution was followed by measuring sugar consumption. Experiments were done in triplicate and the mean and standard deviation are provided.Back to article page
