A bioreactor is a device or system that is used to cultivate and grow biological cells, tissues, or organisms under controlled conditions. Bioreactors provide a controlled environment for cells to grow, allowing for the production of high-quality, consistent products. They are used in many industries such as food, pharmaceuticals, biofuels, and tissue engineering. Bioreactors can come in many different designs and configurations, depending on the desired product and the properties of the microorganisms or cells used. Some examples include stirred tank bioreactors, airlift bioreactors, bubble column bioreactors, fluidized bed bioreactors and photobioreactors.
