(A) β-Galactosidase activities of the A. nidulans ERE-URA-RS reporter strain at various final concentrations of DES. The strain was grown and shifted to induction medium, and the enzyme activity of the reporter was determined after 8 h. bI, before induction. Error bars indicate standard deviations of three independent experiments. (B) β-Galactosidase activities of the A. nidulans ERE-URA-nirA (triangles) and ERE-RS-nirA (circles) reporter strains at various final concentrations of DES. The strains were induced for 8 h, and the enzyme activities were measured.
