Growth phenotypes predicted by the model under a variety of routinely utilized laboratory conditions*
| Light | Dark | |||
|---|---|---|---|---|
| Electron Acceptor | ||||
| O2a | DMSOa | None | ||
| Succinate + NH3 | +/+b | +/- | +/- | -/- |
| Succinate + Glutamate | +/+ b | +/- | +/- | -/- |
| Lactate + NH3 | +/+ b | +/- | +/- | -/- |
| Glutamate only | +/- | +/- | +/- | -/- |
| CO2 + H2 + NH3 | +/- | -/- | -/- | -/- |
| CO2 + H2 + N2 | +/- | -/- | -/- | -/- |
* +/+ Growth and H2 production predicted; +/- Growth but no H2 production predicted; -/- No growth
a Oxygen (O2) or DMSO was used as the sole electron acceptors in simulations.
b Succinate and lactate uptake rates were set to 3 mmol/g DW h, while the NH3 and glutamate uptake rates were set to 1 mmol/g DW h, as these are within the rate of experimentally observed uptake rates for these substrates. CO2, H2 and N2 uptake rates were set to 1 mmol/g DW h for photoautotrophic growth simulations.
