WebSemi-Batch/Fed-batch. In a semi/fed-batch fermentation either the inlet or outlet pipe will be open, but not both i.e if feed is being fed into the reactor, nothing will exit the vessel and vice versa. Since it’s much more beneficial to add feed than remove cells, this is usually run as a fed-batch. A fed-batch operation is when the process ...
