| Abstract: | The titration method reported in the literature was improved to be applied to measure glycerin concentration in the culture broth of glycerin to 1,3-propanediol. The results showed that the titration method possessed good correctness and repeatablity, and the titration result approached to that of the enzyme method and chromotropic acid colourimetry. The titration method was a simple and convient one for determination of glycerin in the bioconversion of glycerin to 1,3-propanediol. |
