The profiles of cell density, 3-HP and other metabolites by strain JJQ02(pUC18-kan-aldH) in a 300-L bioreactor. OD650 (back up-pointing triangle); 3-HP (black circle); PDO: 1,3-propanediol (back down-pointing triangle); BDO: 2,3-butanediol (back left-pointing triangle); acetate (black diamond); the black arrow represents the time point to lower the aeration rate
