چکیده انگلیسی
Repeated batch electrodialysis for lactic acid recovery was investigated using lactic acid solution and fermentation broth. In both cases, lactate fluxes averaged more than 7.0 moles/m2·h, lactate recovery reached more than 99% for all the batch runs, and specific energy consumption per unit lactate transported was lower than 0.25 kWh/kg-lactate. When electrodialysis wastewater was used as a fermentation medium, supplemented with 100 g/l glucose, up to 92.4 g/l lactic acid was produced with a productivity of 0.67 g/l·h. In addition, when electrodialysis wastewater was supplemented with 150 g/l whole-corn flour hydrolyzate and 5 g/l corn steep liquor, 2.5-fold and 1.8-fold increases in lactic acid productivity and maximum cell growth, respectively, were achieved, as compared with lactic acid fermentation using electrodialysis wastewater supplemented with glucose only.
