downstream processing

downstream processing
A general term for biotechnological processes which follow the biology, i.e. fermentation of a micro-organism or growth of a plant. Particularly relevant to fermentation processes, which produce a large quantity of a dilute mixture of substances, products and micro-organisms. These must be separated, and the product concentrated, purified and converted into a useful form.
