Concentrations of pyocyanin and organic acids in culture supernatants after 24 h growth. E. coli BW25113 and P. aeruginosa PA14 were grown in LB either alone or in co-culture, and with or without 4% glucose. Bars indicate mean values (n = 3) and points indicate individual data. Red points indicate samples in which no pyocyanin or acid was detected. Concentrations of acids below 5 µg.mL−1 were recorded as trace amounts
