A fermenter is a system to obtain the desired results by fermentation. Microbes are used for fermentation. Unlike a fermenter, a bioreactor is a system to obtain desired results by cultivating living organisms. Animal and plant cells are used in bioreactors.
A fermenter is a closed type vessel where only fermentation can take place. A bioreactor is also a closed type vessel where many types of biochemical reactions can take place.
Fermenters and bioreactors are utilized for large scaled industrial processes like producing vaccines, pharmaceuticals, wine and beer etc. To keep the cell growth and fertility, temperature, pressure, pH, oxygen and moisture values must be checked and measured continuously.
