☆☆YOUR ANSWER: Batch culture is a technique used to grow microorganisms or cells. It is also known as closed system of cultivation. In this technique at first nutrient solution is prepared and it is inoculated with inoculum (culture organism) and then nothing is added in the fermentation tank except aeration. In batch culture, neither fresh medium is added nor used up media is removed from the cultivation vessel. Therefore volume of culture remains same. Since fresh media is not added during the course of incubation, concentration of nutrition decreases continuously. Furthermore various toxic metabolites also accumulates in the culture vessel. Therefore batch culture technique gives characteristics growth curve with lag phase, log phase, stationary phase and decline phase.
