TL;DR: The purpose of this paper is to discuss the operation of cell recycle systems by membrane filtration and membrane downstream processes for “in-situ” product recovery, stressing the importance of the mutual interaction between the biology and the membrane unit operation used.
Abstract: Successful integration of membrane operations into fermentation processes needs to combine adequate data from microbial physiology and kinetics with physical transport capacities. The understanding of the network of interactions between biology and physics of the integrated process is fundamental to a proper performance. It is the purpose of this paper to discuss the operation of cell recycle systems by membrane filtration and membrane downstream processes for “in-situ” product recovery, stressing the importance of the mutual interaction between the biology and the membrane unit operation used. A particular attention is dedicated to microbial processes strongly affected by product inhibition, as acidogenic fermentations and acetone-butanol-ethanol fermentation.
