An industrial continuous-flow fermenter is used for the large-scale commercial production of mycoprotein using a filamentous fungus.

Explain how the cooling jacket regulates the temperature inside the fermenter.
Explain why it is crucial to keep the temperature near the optimum level for the growing fungus.
Explain the purpose of the stirring impellers (paddles) in the fermenter.
Other than temperature, identify one condition inside the fermenter that must be carefully controlled, and explain the consequence of failing to control it.
Name one specific commercial or medical product, other than mycoprotein, manufactured using this type of bioreactor technology.
