TABLE 3. Mean and maximum lifespan of H. polymorpha cells upon growth on different concentrations of glycerol and glucose in medium buffered to pH 6.5.

The mean lifespan was calculated as a time point when cultures reached 50% viability; the maximum lifespan was calculated as a time point when cultures reached 10% viability. The data represents mean ± SD from at least 4 independent cultures. ND – not determined.
