FIGURE 1: Effect of folic acid (A) and folinic acid (B) on the survival of stationary phase yeast. Cells (10³ cells/ml) were incubated overnight at 30°C with shaking at 200 rpm. Viability was estimated by determination of CFUs. The viability of quiescent (C) and non-quiescent (D) fractions of stationary phase yeast in the presence of 10 μM and 100 μM of folic acid and folinic acid was compared with the control. (*P < 0.05, **P < 0.01, ***P < 0.005). All data are shown as mean +/- SEM.
