Compare the advantages and disadvantages of batch and continuous culture - ️️Growth rate: Batch has lag, log then stationary phase. Continuous has optimum rate maintained. Ease of set up and maintenance: Batch is easy to set up and run. Continuous is not easy, requires sophisticated equipment and constant monitoring and adjustment. Consequence of contamination: Batch has less chance. Loss of product must sterilise and start again. Continuous has more chance and is more costly to restart as...
