3. Results 3.1. Azocasein did not impact yeast growth or alcoholic fermentation In this part we focused on the effect of azocasein on the growth and alcoholic fermentation kinetics of several wine yeast species: S. cerevisiae (X5), T delbrueckii (Alpha), M. pulcherrima (IWBT 1123), and Metschnikowia spp. (CRBO L0563). Several growth and alcoholic fermentation parameters were calculated for each species, as described in materials and methods (Table 2). All fermentations with S. cerevisiae were completed whereas, as expected, T delbrueckii and Metschnikowia cultures stopped at 85% and 65%, respectively.
