ABSTRACT
A fermentor (or fermenter) is a vessel for the growth of microorganisms which, while not permitting contamination, enables the provision of conditions necessary for the maximal production of the desired products. In other words, the fermentor ideally should make it possible to provide the organism growing within it with optimal pH, temperature, oxygen, and other environmental conditions. In the chemical industry, vessels in which reactions take place are called reactors. Fermentors are therefore also known as bioreactors.
