FIG. 2.
Survival of wt L. lactis MG1363 and tellurite-resistant mutants following growth under aerated conditions. Overnight nonaerated cultures were diluted 1 in 1,000 in 2× GM17 and incubated at 30°C with shaking. After 9 and 24 h, viable cell numbers were determined by diluting the cultures and spotting 10 μl onto GM17 agar. Plates were incubated overnight at 30°C. This experiment was performed twice, with similar results observed each time.
