Extraction with water-immiscible solvents is widely used to recover products from fermentation broths, including penicillin and many other antibiotics, though there is little published work on this operation. Formation of rather stable emulsions is often a problem during the process, leading to sign

## Abstract **BACKGROUND:** In this work, the selective extraction of ethanol by pervaporation through a POMS (polyoctylmethyl siloxane) hydrophobic membrane supplied by GKKS (Germany) was investigated. First, binary ethanol aqueous solutions were studied considering the effect of ethanol feed conc
