Study on Physical Properties of Immobile Cell Carrier

Using colloid of keltone as carrier, the yeast cells were embeded and gelatinous particles were produced with centrifugation. It was discovered that the change of colloid's physical property had much influence on the production of gelatinous particles. The paper states how the colloid vis- cosity influences the particle quality. It also tells that temperature, time and agitation ect. are the main factors influencing colloidal viscosity .We have measured and analysed the relation between these factors and visco- sity, and found its regularity. In the meantime, we have also measured and analysed the property of released water of gelatinous particles.
