Abstract
The effects of glycerol concentrations,temperature,pH and aeration strategies were investigated on the production of 1,3-propanediol with glycerol as substrate by Klebsiella pneumoniae. The results showed that the most suitable condition of accumulating 1,3-PDO were glycerol concentrations 40g/L,temperatures37℃,pH7. 0 and aeration rate 0. 5V/V·min,fermentation time 30h,respectively. The PDO concentration in the fermentation broth reached 57. 63g/L.
