To obtain the feed from the process of pervaporation, 0.002 m3 of fermentation broth was produced, as described by Schulz(2010). Rejected banana fruit (Musa cavendishii) was used as lignocellulosic material (500 g L1 wet mass) and 20% (v/v) of inoculum (Saccharomyces cerevisiae). After a period of 10 h of fermentation, different ethanol mass fractions were obtained in broths for pervaporation tests. The total volume of the broth was centrifuged
at 3800 min1 (3018g) for 1200 s in a refrigerated centrifuge and then stored at 277 K.
