Cellular ROS levels of three yeasts and their DhAHP overexpression transformants as affected by salt. Cells of D. hansenii (A), S. cerevisiae (B) and P. methonolica (C) were grown in liquid media with or without salt and in the presence or absence of 0.5% methanol for 5 h. ROS levels, as measured by fluorescence signal, were presented as relative values. Data presented were means +/- S.D. from 3–4 replicates of measurement.
