Abstract
The invention discloses a method for producing 1,3-propanediol, comprising the steps of: using crude glycerol, a by-product during the biodiesel production, without further treatment, as the substrate for production of 1,3-propanediol; inoculating a 1,3-propanediol-producing strain in a seed medium containing crude glycerol, a by-product from biodiesel production; adding the seed culture into a fermentation medium containing crude glycerol, a by-product from biodiesel production, and fermenting; maintaining pH in a range of 6.8 to 8.0; and in the end of the fermentation, isolating and purifying 1,3-propanediol.
