Batch and Continuous Bioreactors | Protocol

Continuous stirred tank reactors exhibit similar growth patterns initially, and reach a constant cell density at steady state operation. However, this cell density is dependent on the dilution rate, which is the feed and effluent rate divided by the reactor volume. Thus, as the dilution rate approaches one, the cell density decreases.
