Bioreactors Factors Controlled Include Temp Low Slow Growth

Factors controlled in bioreactors include temperature, nutrients, O2, and asepsis, with mixing mechanisms ensuring even distribution and resource access.

Fatores controlados em biorreatores incluem temperatura, nutrientes, O2 e assepsia, com mecanismos de mistura garantindo distribuição uniforme e acesso aos recursos.

Front factors that need to be controlled in bioreactors
Back
factors that need to be controlled include;
  • temp (low, slow growth, too high, enzymes denature, maintain optimum temps using negative feedback system)
  • nutrients and O2 (can be added when levels low)
  • mixing things up (mixing mechanism ensures right temp, all microorganisms receive enough O2/food and prevents the large volume of liquids in bioreactors getting too thick/viscous due to growth of microorganisms)
  • asepsis (contamination affects yield, so bioreactors sealed and aseptic)
