Effect of the presence of exogenous 2-PE on the growth of (A) S. uvarum 10–1651, (B) S. kudriavzevii 10–1653 and (C) II/6 hybrid strains. For each strain, five 48-h batch cultures in YPD were conducted. When the cultures reached OD600 values of 0.6–0.8 (indicated by an arrow), 2-PE was added to four cultures to final concentrations of 0.5, 1, 2, and 3 g/L, respectively. The fifth culture was not supplemented with 2-PE and served as a control. Analyses were performed in triplicate and data are presented as the mean ± SD
