In biotechnological processes, foaming often represents an undesired complication. Foam may induce cell death, and may limit the performance of down-stream processing steps. On the other hand, the differences in foamability of compounds can be used for separation of these substances. The process based on this principle is called foam fractionation, and has been subject of increased attention in recent...
Nowadays, the use of enzymes for the pharmaceutical, cosmetic or food industry steadily increases. Although the specification and production of enzymes are steadily enlarged, the downstream processing strategies lag behind. Thus, the development or improvement of enzyme purification methods to efficient and competitive techniques is a main issue. Adsorptive bubble separation e.g. foam fractionation...
