| Abstract: | The conditions of entrapping yeasts by mixed supports, k carrageenan and konjac glucomannan were studied.Through orthogonal experiments,the amount of k carrageenan, konjac glucomannan and deionized water were determined. The shape of immobilized yeasts was observed by scanning electron microscope, which was different between immobilized yeasts and frozen immobilized yeasts.High activity of immobilized yeasts was shown after they were used several times for biosynthesis of CDPC. |
| Keywords: | CDPC immobilized yeasts orthogonal experiment |
