Table 2. MEND model parameter values used for simulation of the experiment described in Fig. 3 of Stolpovsky et al. (2011).
Parameter | Fitted Value* | Initial Range | Description |
mR | 0.032, [0.011–0.048] | 0.001–0.1 | Specific maintenance rate for active biomass (h−1) |
α | 0.099, [0.045–0.181] | 0.001–0.50 | mR/(μG+mR), μG is specific growth rate (h−1) |
Ks | 3.110, [1.387–5.652] | 0.1–9.0 | Half-saturation constant for substrate (mg L−1) |
YG | 0.573, [0.463–0.600] | 0.2–0.6 | Growth yield factor (–) |
Ko | 0.0008, [0.0007–0.001] | 0.005–0.1 | Half-saturation constant for dissolved oxygen (mM) |
β | 0.351, [0.001–1.000] | 0.001–1 | Ratio of dormant maintenance rate to mR |
r 0 | 0.925, [0.628–1.000] | 0–1 | Initial fraction of active biomass (–) |
*Medians and 95% confidence intervals of the fitted values from 100 optimization runs, i.e., 100 different random seeds are used for the stochastic optimization algorithm.
