Fermentation performance of the mono-culture and the synthetic microbial consortia at 0.02 vvm N2 supply for 3 h under fed-batch fermentation A OD650nm; B 1,3-PDO concentration; C butyrate concentration; D lactate concentration; E yield and productivity. Fermentation was carried out at 37 °C, pH 7.0 and 200 rpm in 5-L bioreactor containing 2 L medium. Residual glycerol controlled around 40 g/L. *Represented 0.2 vvm N2 supply for 3 h
