Enhanced Bioethanol Production in Batch Fermentation by Pervaporation Using a PDMS Membrane Bioreactor

The integration of batch fermentation and membrane-based pervaporation process in a membrane bioreactor (MBR) was studied to enhance bioethanol production compared to conventional batch fermentation operated at optimum condition. For this purpose, a laboratory-scale MBR system was designed and fabricated. Dense hydrophobic Polydimethylsiloxane (PDMS) membrane was used for pervaporation. For fer...

Coupling of Pervaporation system with Fermentation Process Coupling of Pervaporation system with Fermentation Process

The ethanol fermentation process using beet molasses as the feedstock has been studied. The fermentation process, which was coupled with a membrane separation unit (Pervaporation), was compared to a conventional batch process. Ethanol was produced by Saccharomyces cerevisiae ATCC 9763 and recovered by pervaporation system using a composite polydimethylsiloxane (PDMS) membrane with 10 μm thickne...
