Main Results:

  • Identification of key static and dynamic effectors affecting microbial cultures.
  • Distinction between macroscopic steady states (e.g., biomass concentration) and physiological steady states (e.g., metabolic activity).
  • Examples include medium component effects, operational pitfalls, foam control, alternative nutrient/oxygen supply, and cell cycle influences.

Conclusions:

  • Effective microbial cultivation requires understanding both static and dynamic parameters.
  • Recognizing different steady states aids in process optimization and troubleshooting.
  • This framework supports the development of more robust and efficient bioprocesses.
