Increasing the productivity of bioconversion processes
- University College London (United Kingdom). Advanced Center for Biochemical Engineering
In some syntheses, product formation can cause problems that limit overall productivity. This is frequently the case in bioprocesses, especially in bioconversions, because the product may inhibit or damage the biological catalyst or interfere with other components in the reaction medium. Many reactions are reversible, so yields decrease when the product is allowed to accumulate in the reactor. Some desired products may be unstable or reactive under the conditions of the reaction. Any of these conditions can limit the maximum conversion or product concentration. However, many limitations can be overcome with in situ product removal (ISPR), a family of techniques in which the product is removed as it is synthesized. The authors have devised a systematic approach to identify the most suitable process options for the design and operation of bioconversion processes, emphasizing the integration of upstream (i.e., catalyst production) and downstream (i.e., product recovery) operations. The paper discusses separation principles, ISPR integration, choosing the best techniques, application of ISPR to bioconversion processes, and system design.
