However, the conversion rate of glycerol produced from the first stage using cornstarch to 1,3-propanediol from the second stage was only 26.5 % in 31h and the final concentration of 1,3-propanediol was 13.4 g/L. The productivity of 0.43 g/ of the second stage was much lower than that of a two-stage-fermentation from glucose （1.65g/ L） or of single fermentation from saponified glycerol, which is

多年来，研究人员在甘油生物歧化过程的代谢途径、动力学特征等方面已进行了较为深入的研究，甘油作为唯一碳源的最大理论摩尔转化率为72％，辅助底物的使用可以将甘油转化率提高至100％，发酵液中1，3一PD的最终浓度可以达到65～70 g／L3 。。。。。。

Content of water-soluble material— Disperse about 10 g, accurately weighed, in 800 mL of water, accurately measured, and stir for 1 minute every 10 minutes during the first 30 minutes. Allow to stand for an additional hour, or centrifuge, if necessary. Decant about 200 mL of the aqueous slurry onto a rapid-filtering filter paper in a vacuum filtration funnel, apply vacuum, and collect about 150 mL of the filtrate. Pour the filtrate into a tared 250-mL beaker, weigh accurately, and calculate the weight, in g, of the filtrate, W3, by difference.
