Study Notes

Bioreactors and Fermentation

A bioreactor is often used synonymously with a fermenter.
Fermenters are made up of a vessel, agitation system, aeration system, temperature control system, pH control system, and sensors.
Fermentation is referred to as the process of converting sugars into other compounds using microorganisms or cells.

Purpose and Importance of Bioreactors

The primary purpose of a bioreactor is to provide a controlled environment for cells or microorganisms to grow and produce desired biomolecules.
Understanding mass transfer behavior in bioreactors is important because it affects the availability of nutrients and oxygen to cells, which in turn affects cell growth and product formation.
A bioreactor provides a controlled environment, which is essential for the production of useful biotechnological products from cell systems.

Optimizing Bioreactor Conditions

Maximizing reaction rates in bioreactors requires optimal concentrations of reactants, optimal pH and temperature, and sufficient mixing and aeration.
Important parameters that need to be closely monitored in a bioreactor include pH, temperature, oxygen levels, nutrient concentrations, and cell density.
