Comparative growths of the engineered strains using acetic acid. The engineered strains E. coli BL21(DE3)/pCOLADUet-1 (a), BL21(DE3)/pYJM60 (b), BL21(DE3)/pYJM62 (c) and BL21(DE3)/pYJM61 (d) grew on different concentrations of acetate. The OD600 was measured spectrophotometrically. The experiment was performed in triplicate
