Bioreactor vs. Fermenter: Know the Difference
By Shumaila Saeed || Published on January 31, 2024
A bioreactor is a device for growing organisms under controlled conditions, while a fermenter specifically facilitates fermentation, often for brewing or biochemical production.
Key Differences
Bioreactors are used for a variety of bioprocesses, including tissue engineering and cell cultures. Fermenters are primarily used for fermentation processes, like brewing beer and producing yogurt.
