Abstract

Immobilized microbe composite comprising a porous, high surface area inorganic support having a controlled population of microbes bonded to the internal surfaces of the pores, the support being water insoluble, non-toxic to the microbes, 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 major dimension of the microbes but less than about five times the largest major dimension of the microbes. The composites are especially useful in situations requiring a high biomass surface within a relatively small volume.
