Figure 2From: Increased expression of the yeast multidrug resistance ABC transporter Pdr18 leads to increased ethanol tolerance and ethanol production in high gravity alcoholic fermentationPDR18 expression decreases intracellular ethanol accumulation. Comparison of [3 H]-ethanol accumulation in non-adapted cells of S. cerevisiae parental strain BY4741 (▴) and the derived deletion mutant Δpdr18 (■), during cultivation for 30 min in MM4 liquid medium supplemented with 6 % cold ethanol. The accumulation ([3 H-Eth]intra/[3 H-Eth]extra) values are the means of at least three independent experiments, error bars indicating standard deviation.Back to article page
