Differentiate between Batch and Continuous Culture Fermentation

Difference between Batch media and Continuous media. 

Batch Fermentation: 

1. It is carried out in a closed fermenter. During the process nothing added or removed(except venting of gas). 
2. The process is set up and run easily. Instrumentation is not complex at all.
3. The fermenter has to be washed before the subsequent step of fermentation is undertaken. 
4. Environmental conditions in the fermenter are never keep constant in batch Fermentation. 
5. Nutrients are used by the microorganisms in slower rate.
6. In this fermenter microbes show lag, log and stationary growth phases.
7. When the product is formed the process will end.
8. Batch fermentation has a huge application in industrial production.

Continuous fermentation:

1. Fermentation is carried out in an open fermenter. In this fermenter nutrients is added and product removed at steady rate throughout the process.
2. The process is not that easy to setup. Instrumentation is complex.
3. The fermenter is never washed before the subsequent steps of fermentation because there is continuous addition of nutrients and microbes.
4. Environmental conditions in the fermenter will always constant in continuous fermentation. 
5. Nutrients are utilized rapidly by microorganisms.
6. Optimum or exponential growth rate of microbes is maintained in the fermenter.
7. Continuous fermentation has a limited application in industrial production.
