Batch Fermentation vs Continuous Fermentation Process (Similarities and difference between Batch Fermentation and Continuous Fermentation Process)
Batch Fermentation and Continuous Fermentation are the two commonly adopted Industrial Fermentation methods for the scale production of microbial biomass or metabolites.
Batch Fermentation: Here the fermenter is first filled with the raw material (carbon source). Then the microbes are added and allowed to ferment the raw material under optimum pH and aeration. The products remain in the fermenter until the completion of fermentation. After fermentation, the products are extracted and the fermenter is cleaned and sterilized before next round. Thus here the fermentation is done as separate batches.
Continuous Fermentation: Here the exponential growth rate of the microbes is maintained in the fermenter for prolonged periods of time in by the addition of fresh media are regular intervals. The metabolite or the product of fermentation is extracted for the overflow from the fermenter. Thus unlike batch fermentation, in continuous fermentation, the fermentation process never stops in between and it continues to run for a long period of time with the addition of nutrients and harvesting the metabolites at regular intervals.
The present post describes the Similarities and Differences between Batch Fermentation and Continuous Fermentation Process as a Comparison Table.
Similarities between Batch Culture and Continuous Culture Fermentation Methods
Ø Both are industrial fermentation methods for the large scale production.
Ø Both methods can be used for the production of microbial biomass or products.
Ø Both run under controlled environmental conditions
Ø The mechanical components of fermenter is almost similar in both types
