Fig. 2.

Growth of S. cerevisiae BY4741 and BY4741 opi1Δ strains in the absence and in the presence of lactic acid. Cells were grown in shake flasks in minimal (YNB) medium with 2 % w/v glucose without (left panel) or with (right panel) 46 g/L lactic acid at pH3. Growth was determined as OD at 660 nm. Light grey full squares: BY4741 strain. Open squares: BY4741 opi1Δ strain. The data reported here are representative of three independent experiments (variation < 3 %)
