Abstract

Immobilized microbe composite comprising a porous, high surface area inorganic support having a controlled population of yeast cells bonded to the internal surfaces of the pores, the support being water insoluble, non-toxic to the cells, and having a controlled porosity such that at least 70% of the pores, on a pore size distribution basis, have a pore diameter at least as large as the smallest dimension of the cells but less than about four times the largest dimension of the cells. The composites are especially useful in situations requiring a high biomass surface within a relatively small volume.
