03 · Growth & electron-transfer kinetics
Growth & electron-transfer kinetics
How fast this organism grows and how hard it pushes electrons into an anode, as the corpus reports it, and what those constants imply when you run them.

Genus-level prior: Thauera spp.
A genus-level prior is a summary for the whole genus, not a measurement on this strain.
Constants that drive the simulation
Scenario — values you set, not evidence
Growth simulation
Scenario: Initial substrate 1000 mg/L · Initial attached biomass 0.1 g/m² · Anode area per liquid volume 100 m²/m³ · Duration 72 h · Batch. Values you set, not evidence.
No current model
The current needs Max. current density jmax, Half-saturation potential E_KA, which this source does not have.
- Substrate-saturated growth
- Slowing
- Stationary
Monod growth has no lag phase; the bands mark where the net growth rate is near its maximum, falling, near zero or negative.
Simulator notes
- decayPerH absent: no endogenous decay term, so growth is an upper bound
- biofilmDensityKgPerM3 absent: thickness not computed (thicknessUm = null)
- no anodePotentialVvsShe / overpotentialV given: current not computed (currentDensityAPerM2 = null)
These curves are a Monod and Nernst-Monod idealisation (after Marcus et al. 2007 and Torres et al. 2008), parameterised only by the constants listed above: each one carries its n and its 10–90 % range, and a constant with n = 1 has no spread at all. No diffusion inside the biofilm, no detachment, no coulombic-efficiency split. The scenario values are yours, not evidence.
