Medium-chain fatty acids (MCFAs) are promising platform chemicals for biorefineries in the circular economy. An efficient and sustainable process for their recovery from biomass, however, remains elusive. This work aimed to develop a separation cascade for MCFA recovery from fermentation broth (FB) using membrane filtration. This technical-scale pr...
Production of caproic and caprylic acid through anaerobic fermentation of crops or residual and waste biomass has been regarded as an alternative to the conventional ways, where plant oils and animal fats are mostly used. The downstream processing of the fermentation broth is a particular challenge since the broth has a highly complex composition a...
A membrane filtration cascade was designed for the recovery of MCFAs from fermentation broth. Supervised by: Professor Dirk Enke (University of Leipzig) Roy Nitzsche and Maria Braune (DBFZ)
