Comparison of Batch Culture and Continuous Cultivation

01/05/2000  Comparison of Batch Culture and Continuous Cultivation In batch cultivation, the bacteria are inoculated into the bioreactor (always stirred tank bioreactor). Then, under certain conditions (temperature, pH, aeration, etc.) the bacteria go through all the growth phases (lag, exponential, stationary). At last, the fermentation is stopped and the product is collected. Then,

Difference Between Batch and Continuous Culture -

26/06/2018  The main difference between batch and continuous culture is that batch culture is a closed system that carries out fermentation with a fixed amount of nutrients whereas continuous culture is an open system, which continuously carries out fermentation. Furthermore, nutrients become a limiting factor after a certain point in a batch culture while nutrients are

Difference between Batch Continuous Fermentation Easy ...

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
