“…Waste fruits may also represent a substrate for bioethanol production. For example, banana waste or rotten banana, peels and sub-quality fruits have been extensively studied as substrates for bioethanol production (Graefe et al, 2011;Oberoi et al, 2011;Hossain et al, 2011;Arumugam and Manikandan, 2011;Gonçalves Filho et al, 2013;Bello et al, 2014).…”

“…The application of PV to recover ethanol from lignocellulosic residues is already investigated in the literature with fermentation broth from barley straw and willow wood, food waste after a flocculation‐filtration pretreatment and corn fiber hydrolysates . Banana waste as a substrate for ethanol production is reported elsewhere . However, some authors have observed that the presence of by‐products and inhibitors in the fermented broth can modify the parameters of separation of the pervaporation process .…”

In this work, we performed recovery of ethanol from a fermentation broth of banana pseudostem by pervaporation (PV) as a lower‐energy‐cost alternative to traditional separation processes such as distillation. As real fermentation systems generally contain by‐products, it was investigated the effects of different components from the fermentation broth of banana pseudostem on PV performance for ethanol recovery through commercial flat sheet polydimethylsiloxane (PDMS) membrane. The experiments were compared to a binary solution (ethanol/water) to determine differences in the results due to the presence of fermentation by‐products. A real fermented broth of banana pseudostem was also used as feed for the PV experiments. Seven by‐products from fermented broth were identified: propanol, isobutanol, methanol, isoamyl alcohol, 1‐pentanol, acetic acid, and succinic acid. Moreover, the residual sugar content of 3.02 g/L1 was obtained. The presence of methanol showed the best results for total permeate flux (0.1626 kg·m−2·h−1) and ethanol permeate flux (0.0391 kg·m−2·h−1) during PV at 25°C and 3 wt% ethanol, also demonstrated by the selectivity and enrichment factor. The lowest total fluxes of permeate were observed in the experiments containing the acids. Better permeance of 0.1171 from 0.0796 kg·m−2·h−1 and membrane selectivity of 9.77 from 9.30 were obtained with real fermentation broth than with synthetic solutions, possibly due to the presence of by‐products in the multicomponent mixtures, which contributed to ethanol permeation. The results of this work indicate that by‐products influence pervaporation of ethanol with hydrophobic flat sheet membrane produced from the fermented broth of banana pseudostem.
