Fig. 3From: Efficient 3-hydroxypropionic acid production from glycerol by metabolically engineered Klebsiella pneumoniaeThe profiles of cell density, 3-HP and other metabolites by strain JJQ02(pUC18-kan-aldH) in fed-batch fermentation in a 5-L bioreactor. OD650 (back down-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 rateBack to article page
