Fed Batch Culture - Although batch and continuous culture are used most frequently in the laboratory and are most useful for experimental work, industrial processes often use a hybrid of the two techniques called fed batch culture. This involves ordinary batch growth until the substrate is fully utilised, followed by regular additions of fresh substrate which is then rapidly metabolised.

The total culture volume may be allowed to increase or portions may be removed as fresh substrate is added. This type of culture was developed empirically but microbiologists are now initiating to understand the physiology of growth under such conditions and the reasons for its efficiency in terms of product formation, yield and greater control. This may lead to further advances in industrial microbiology
