An analysis of extended and exponentially‐fed‐batch cultures

Abstract

Under certain conditions it is shown that an extended culture is equivalent to an exponentially‐fed‐batch culture, that an exponentially‐fed‐batch culture (and an extended culture) can be maintained at a steady state and that an exponentially‐fed‐batch culture may be mimicked by a continuous‐flow culture with a constant dilution rate. Operational conditions required to maintain steady states are specified.
