Abstract

Provided is a preparation method of a yeast cell immobilization medium, which comprises the following steps: (1) boiling a fiber material in boiling water and drying the fiber material; (2) soaking the fiber material in a surface modified aqueous solution with a concentration of 1-100 g/L, using hydrochloric acid to adjust a PH of the solution to 7.0, fully rinsing the fiber material in deionized water and drying the fiber material; (3) soaking the fiber material in a cross-linking agent aqueous solution with a concentration of 1-100 g/L, fully rinsing the fiber material in deionized water and drying the fiber material; and (4) attaching the fiber material to supporting framework. Also provided is the yeast cell immobilization medium prepared using the preparation method and a method for producing ethanol using the yeast cell immobilization medium.
