Figure 1.

Growth of yeast strains in the presence of H₂O₂. Yeast from late log phase cultures was inoculated into yeast synthetic medium lacking leucine at 1:300 dilution and grown aerobically at 30°C with H₂O₂ (2 mM). ■, Wild-type parental strain; •, msrA null mutant strain; ▴, overproducer strain.
