Differnces between batch and continuous

BATCH :

1. It is a closed system.
2. All four phases of microbial growth is present.
3. Primary and secondary metabolite are produced.
4. Nutrients are added only one not in between the fermentation process.
5. Process is stopped after the product is formed.
6. Environment conditions inside the batch culture are not constant.

CONTINUOUS:

1. It is an open system.
2. Only lag or exponential phase is present.
3. No secondary metabolite production.
4. Nutrients are added in between the process.
5. Process is not stopped and product is removed.
6. Environment conditions are maintained at constant rate.
