Hydrophobic organic-inorganic composite membranes with cross-linked poly(dimethyl siloxane)-poly(methyl hydrogen siloxane) (PDMS/PMHS) were prepared on a porous alumina tubular support. The PDMS/PMHS polymer penetrated into and plugged the pores of the β₯-alumina support. The membrane had an approxim
## Abstract **BACKGROUND:** A closedβcirculating system for ethanol fermentation was constructed by coupling a cellβimmobilized bed fermentor with pervaporation using a composite PDMS membrane. A continuous fermentation experiment was carried out for about 250 h in the system at 28 Β°C. **RESULTS:*
