Cell Division

class ecoli.processes.cell_division.Division(parameters=None)

Bases: Step

Division Deriver

• Uses dry mass threshold that can be set in config via division_threshold

• Samples division threshold from normal distribution centered around what is expected for a medium when division_threshold == massDistribution

• If flag d_period is set to true (default), mass thresholds are ignored and the same D period mechanism as wcEcoli is used.

defaults: Dict[str, Any]
