Abstract
Abstract Immobilized microbe composite comprising a porous, high surface area inorganic support having a controlled population of fungus-like 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 diameter of the fungal spore but less than about sixteen times the largest spore diameter. The composites are especially useful in situations requiring a high biomass surface within a relatively small volume.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
83 words
An immobilized microbe composite comprising a porous, high surface area inorganic support having a controlled population of fungus-like 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 spore dimension of the microbes but less than about sixteen times the largest major dimension of the spore.
Claim 2
Dependent Claim
83 words
An immobilized microbe composite comprising a porous, high surface area inorganic support having a controlled population of fungus-like 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 spore dimension of the microbes but less than about sixteen times the largest major dimension of the spore.
Claim 3
Dependent Claim
16 words
The composite of claim 1 wherein the population of microbes comprises fungi of a single species.
Claim 4
Dependent Claim
13 words
The composite of claim 1 wherein the inorganic support comprises an amorphous material.
Claim 5
Dependent Claim
11 words
The composite of claim 3 wherein the support comprises fritted glass.
Claim 6
Dependent Claim
13 words
The composite of claim 1 wherein the inorganic support comprises a crystalline material.
Claim 7
Dependent Claim
12 words
The composite of claim 5 wherein the support comprises a cordierite-like material.
Claim 8
Dependent Claim
13 words
The composite of claim 5 wherein the support comprises a spinel-zirconia crystalline material.
Claim 9
Dependent Claim
26 words
The composite of claim 1 wherein intermediate the support surfaces and the microbes is a coating material selected from residues of polyisocyanates and silane coupling agents.
Claim 10
Dependent Claim
25 words
The composite of claim 1 wherein the microbes comprise spores of a fungus selected from the group of Aspergillus niger, Streptomyces olivochromogenes, and Penicillium chrysogenum.
Claim 11
Independent Claim
114 words
A method of preparing a high surface area, low volume biomass composite comprising the step of exposing an aqueous spore or mycelial suspension of a controlled population of fungi-like microbes to a sterilized porous inorganic support material having a porosity such that at least 70% of the pores, on a pore size distribution basis, have pore diameters at least as large as the smallest spore dimension of the microbes but less than about sixteen times the largest major dimension of the spore of the microbes, the exposure being under conditions sufficient to result in the bonding of at least some of the microbes onto the internal surfaces defining the pores of the support material.
Claim 12
Independent Claim
114 words
A method of preparing a high surface area, low volume biomass composite comprising the step of exposing an aqueous spore or mycelial suspension of a controlled population of fungi-like microbes to a sterilized porous inorganic support material having a porosity such that at least 70% of the pores, on a pore size distribution basis, have pore diameters at least as large as the smallest spore dimension of the microbes but less than about sixteen times the largest major dimension of the spore of the microbes, the exposure being under conditions sufficient to result in the bonding of at least some of the microbes onto the internal surfaces defining the pores of the support material.
Claim 13
Dependent Claim
31 words
