The present subject matter discloses a bioreactor apparatus. The bioreactor apparatus comprises a bioreactor vessel configured to culture cells. The bioreactor apparatus furthermore comprises a sensor configured to measure Dissolved Oxygen (DO) in the bioreactor vessel. The DO measurements comprise a plurality of DO values recorded at, at least, a plurality of time instances during operation of the bioreactor apparatus. The bioreactor apparatus furthermore comprises a controller configured to obtain the DO measurements. The controller furthermore is to determine, in real-time or approximately real-time, an oxygen mass transfer co-efficient (kLa) associated with the operation of the bioreactor apparatus. Furthermore, the controller is configured to control, in real-time or approximately real-time, at least one cell culture parameter associated with the operation of the bioreactor apparatus based on the kLa.
