Growth of D. hansenii and its DhAHP overexpression transformant as affected by salt. Cells were cultured in YM11 media with or without 3.5 M NaCl and in the presence or absence of methanol for 5 days. W-M: wild type strain, without methanol, W+M: wild type strain, with 0.5% methanol, T-M: transformant, without methanol, T+M: transformant with 0.5% methanol. Data presented were means +/- S.D. from 3–4 replicates of measurement.
