Continuous culture has an advantage over to a batch cultures as

#Section 5: Bioprocess Engineering and Process Biotechnology
  1. continuous reactors do not need to be shut down and cleaned as regularly as a batch reactor
  2. most downstream and upstream processes are continuous in nature and thus the operation of continuous bioreactor can be better integrated into the overall manufacturing process
  3. cells can be maintained at a constant physiological state simply by setting the dilution rate
  4. all of the above
