FORFARANDE FOR FRAMSTELLNING AV EN HYDROFIL KOMPLEX XEROGEL VARI MIKROBCELLER ER IMMOBILIERADE

摘要

Immobilization of microorganisms is carried out by mixing a water soluble-polymer selected from polyvinylalcohol, gelatin and carboxymethylcellulose with a tetraalkoxysilane, hydrolyzing the resulting mixture by the addition of acid to form a homogeneous complex sol, dispersing microbial cells homogeneously in the sol and gelling the mixture of the sol and microbial cells.
