Fig.1From: Improvement of 1,3-propanediol production from crude glycerol by co-cultivation of anaerobic and facultative microbes under non-strictly anaerobic conditionsComparison of 1,3-PDO and byproducts production by the mono-culture and the co-culture at different inoculation ratios without N2 supply. The fermentations were carried out at 37 °C and 200 rpm in 250-mL bottle containing 200 mL medium. The fermentations with the KP mono-culture, the CB mono-culture, the synthetic CB:EC co-culture under anaerobic conditions were lasted for 24 h and other groups were 48 h. (*Anaerobic conditions: 0.2 vvm N2 supply for 3 min.)Back to article page
