| Abstract: | Immobilized cells of Trichosporon pollulans 122 were made by entrapping T.pollu-lans cells in a mixed gel containing Na-alginate and gelatin to form beads,followed by cross-linking the beads with glutaraldehyde solution. Some properties of immobilized cells including optimum pH,optimum temperature,pH and thermal stabilities, the tolerance to CN-, S2- and metallic ions,and cellular stability etc. were comparatively studied with those of free cells. The Km and Vm values of both cells were determined. The properties of immobilized cells fluidized-bed bioreactor had been investigated for continuous treatment of phenol. |
