Differentiate between Batch Fermentation and Fed-Batch Fermentation.

Fed-batch fermentation is a production technique in between batch and continuous fermentation. ... Fed-batch fermentation is distinguished from batch fermentation by the addition, during operations, of a certain amount of fresh substrate and by the consequent withdrawal of a proportioned amount of broth.Batch fermentation is a process where all the substrate and nutrients are added at zero time or soon after inoculation takes place, and the vessel is allowed under a controlled environment to proceed until maximum end product concentration is achieved..Fed-batch culture is, in the broadest sense, defined as an operational technique in biotechnological processes where one or more nutrients are fed to the bioreactor during cultivation and in which the product remain in the bioreactor until the end of the run.
