An extruded shape diatomaceous earth biocarrier for biologically active substances (e.g. enzymes) and cells having a mean pore diameter of at least about 20 microns. The biocarrier is made from either calcined or flux-calcined diatomite having a particle size of about 10 microns or greater and a mean pore diameter of about 5 microns or greater. The inventive biocarrier has a greater mean pore diameter and hardness compared to traditional biocarrier materials. |
