Advantages and disadvantages of batch cultures

Advantages

  • Easy to set up and maintain
  • If contamination occurs, only one batch is lost
  • Very useful for processes involving the production of secondary metabolites

Disadvantages

  • The growth rate is slower because nutrient levels decline with time
  • Batch cultures are less efficient as the fermenter is not in operation all the time

Evaluation

The microorganism starter population is added and allowed to grow for a fixed period with no further nutrient added. At the end of the period the products are removed and the fermentation tank is cleaned. E.g. Insulin
