Fig. 3From: A novel biocatalyst, Enterobacter aerogenes LU2, for efficient production of succinic acid using whey permeate as a cost-effective carbon sourceEffects of different lactose concentrations on the succinic acid production (a) and cell growth (b) of Enterobacter aerogenes LU2 under batch fermentation at 34 °C with stirring at 250 rpm in a 3-L bioreactor. Dashed lines and solid lines with the same colour and symbol represent the lactose, the corresponding succinic acid concentration and the cell growth as follows: 60 g/L lactose (purple), 80 g/L lactose (orange), 100 g/L lactose (pink), 120 g/L (green) lactose, and 140 g/L lactose (blue). The values are the means of three independent samples. Bars represent standard deviationsBack to article page
