Abstract
Abstract A device suitable for seeding bacterial cultures to waste flowing through or which has accumulated in a collection system which comprises a porous outer covering member which forms an enclosed package with a source of bacterial cultures contained within said package, said cultures suitable for seeding a collection system as a waste stream flows through the porous covering member of said enclosed package causing the bacteria to be released into said waste stream.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
108 words
A device suitable for seeding bacterial cultures to waste flowing through or which has accumulated in a collection system which comprises: (a) a porous fabric outer covering member which forms an enclosed package, and (b) a source of dried bacterial cultures contained on a carrier and confined within said package, said cultures suitable for seeding a collection system as a waste stream flows through the porous covering member of said enclosed package causing the bacteria to be released into said waste stream, and (c) said package further containing at least one material selected from the group consisting of nitrogen salts, phosphorus salts, organic substrate, buffers, enzymes and surfactants.
Claim 2
Independent Claim
108 words
A device suitable for seeding bacterial cultures to waste flowing through or which has accumulated in a collection system which comprises: (a) a porous fabric outer covering member which forms an enclosed package, and (b) a source of dried bacterial cultures contained on a carrier and confined within said package, said cultures suitable for seeding a collection system as a waste stream flows through the porous covering member of said enclosed package causing the bacteria to be released into said waste stream, and (c) said package further containing at least one material selected from the group consisting of nitrogen salts, phosphorus salts, organic substrate, buffers, enzymes and surfactants.
Claim 3
Dependent Claim
29 words
The device of claim 1 in which the package is enclosed in a protective outer casing which includes means to allow the waste stream to directly contact said package.
Claim 4
Dependent Claim
20 words
The device of claim 1 further includes means for fastening the device at a selected location within a waste stream.
Claim 5
Dependent Claim
27 words
The device of claim 1 in which the bacterial cultures comprise at least one species of Bacillus, Pseudomonas, Escherichia, Arthrobacter, Achromobacter, Flavobacterium or Bdellovibrio and mixtures thereof.
Claim 6
Independent Claim
104 words
A device suitable for seeding bacterial cultures to waste flowing through or which has accumulated in a collection system which comprises: (a) a porous fabric outer covering member which forms an enclosed package, and (b) a source of dried bacterial cultures contained on a carrier and confined within said package with said carrier consisting of at least one material selected from the group consisting of bran base, rice hulls and peanut hulls, said cultures suitable for seeding a collection system as a waste stream flows through the porous covering member of said enclosed package causing the bacteria to be released into said waste stream.
Claim 7
Independent Claim
104 words
A device suitable for seeding bacterial cultures to waste flowing through or which has accumulated in a collection system which comprises: (a) a porous fabric outer covering member which forms an enclosed package, and (b) a source of dried bacterial cultures contained on a carrier and confined within said package with said carrier consisting of at least one material selected from the group consisting of bran base, rice hulls and peanut hulls, said cultures suitable for seeding a collection system as a waste stream flows through the porous covering member of said enclosed package causing the bacteria to be released into said waste stream.
Claim 8
Dependent Claim
29 words
The device of claim 5 in which the package is enclosed in a protective outer casing which includes means to allow the waste stream to directly contact said package.
Claim 9
Dependent Claim
27 words
The device of claim 5 in which the package further contains at least one of the following: nitrogen salts, phosphorus salts, organic substrate, buffers, enzymes and surfactants.
Claim 10
Dependent Claim
20 words
The device of claim 5 further includes means for fastening the device at a selected location within a waste stream.
Claim 11
Dependent Claim
27 words
The device of claim 5 in which the bacterial cultures comprise at least one species of Bacillus, Pseudomonas, Escherichia, Arthrobacter, Achromobacter, Flavobacterium or Bdellovibrio and mixtures thereof.
Claim 12
Independent Claim
126 words
A method for biodegrading waste flowing through or which has accumulated in a collection system, grease trap, chemostat or bioreactor which comprises: (a) providing a porous fabric outer covering member which forms an enclosed package, and which contains a source of dried bacterial cultures contained on a carrier and confined within said package, said cultures suitable for seeding a collection system as a waste stream flows through the porous covering member of said enclosed package causing the bacteria to be released into said waste stream, said package further containing at least one material selected from the group consisting of nitrogen salts, phosphorus salts, organic substrate, buffers, enzymes and surfactants, (b) placing said package within a waste stream whereby said package seeds said stream with biodegrading cultures.
Claim 13
Independent Claim
126 words
A method for biodegrading waste flowing through or which has accumulated in a collection system, grease trap, chemostat or bioreactor which comprises: (a) providing a porous fabric outer covering member which forms an enclosed package, and which contains a source of dried bacterial cultures contained on a carrier and confined within said package, said cultures suitable for seeding a collection system as a waste stream flows through the porous covering member of said enclosed package causing the bacteria to be released into said waste stream, said package further containing at least one material selected from the group consisting of nitrogen salts, phosphorus salts, organic substrate, buffers, enzymes and surfactants, (b) placing said package within a waste stream whereby said package seeds said stream with biodegrading cultures.
Claim 14
Dependent Claim
29 words
The device of claim 10 in which the package is enclosed in a protective outer casing which includes means to allow the waste stream to directly contact said package.
Claim 15
Independent Claim
125 words
A method for biodegrading waste flowing through or which has accumulated in a collection system, grease trap, chemostat or bioreactor which comprises: (a) providing a porous fabric outer covering member which forms an enclosed package, and which contains a source of dried bacterial cultures contained on a carrier and confined within said package, with said carrier consisting of at least one material selected from the group consisting of bran base, rice hulls and peanut hulls, said cultures being suitable for seeding a collection system as a waste stream flows through the porous covering member of said enclosed package causing the bacteria to be released into said waste stream, (b) placing said package within a waste stream whereby said package seeds said stream with biodegrading cultures.
