Abstract: The preparation process of biocatalyst by immobilizing yeast cells in the honeycomb-like ceramics was studied. Theoptimum process conditions, that is, adsorbing 30min and continuous culturing 2h in the reactor at 14℃, were achieved. Underdifferent temperature, the kinetic models of the honeycomb-like ceramics for adsorbing yeast cells also were obtained.
