In situ Product Recovery of Microbially Synthesized Ethyl Acetate from the Exhaust Gas of a Bioreactor by Membrane Technology.

ABSTRACT: Ethyl acetate is at present exclusively produced from fossil resources. Microbial synthesis of this ester from sugar-rich waste as an alternative is an aerobic process. Ethyl acetate is highly volatile and therefore stripped with the exhaust gas from the bioreactor which enables in situ product recovery. Previous research on microbial formation of ethyl acetate has focused on the kinetics of ester synthesis and in part on the ester stripping, while the separation of the ester from the exhaust gas has hardly been investigated. A mixed matrix membrane was developed consisting of Silikalite-1 embedded in polydimethylsiloxane which was installed in a radial-symmetrical membrane module. Evaluation of the separation of ethyl acetate was based on the analysis of the composition of the feed and re
