Effects of oxygen-radical treatment of vanillin on the growth of S. cerevisiae. The yeast was grown in YPD medium supplemented with a 0 mM, b 1 mM, c 2.5 mM, and d 5.0 mM vanillin with or without oxygen-radical treatment. Yeast growth was monitored by measuring optical density at 600 nm. Error bars represent the mean ± standard error of the mean of three independent experiments
