A number of downstream processing methods are available for concentrating and recovering partially or highly purified products produced in the bioreactor. In the case of intracellular products, the cells are harvested and then disintegrated to release the product. Before packed bed chromatography operations the product is separated from particulate matter like cell debris. We have great experience of continuous centrifugation, cell disintegration, cross flow membrane filtration, and extraction in aqueous two-phase systems. In the case of extracellular products the cells are removed by centrifugation, cross flow filtration or expanded bed adsorption.
