Abstract
Abstract Manure from stockyards is treated in a single step by the addition of both a bacteria (L. plantarum) and a fermentable carbohydrate (lactose). The pH of the treated manure falls to below 4.0. The manure without more is acceptable as landfill or with further treatment as cattle feed.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
78 words
A method for the treatment of manure which treatment renders the manure environmentally acceptable which includes: inoculating the manure with Lactobacillus, the manure per se containing the nutritional requirements for the Lactobacillus; and admixing a fermentable carbohydrate in an effective amount with manure, the Lactobacillus inoculated and the carbohydrate admixed in an amount sufficient to lower the pH of the manure to below 4.5 whereby the manure is stabilized and rendered substantially free of coliform and pathogenic bacteria.
Claim 2
Independent Claim
78 words
A method for the treatment of manure which treatment renders the manure environmentally acceptable which includes: inoculating the manure with Lactobacillus, the manure per se containing the nutritional requirements for the Lactobacillus; and admixing a fermentable carbohydrate in an effective amount with manure, the Lactobacillus inoculated and the carbohydrate admixed in an amount sufficient to lower the pH of the manure to below 4.5 whereby the manure is stabilized and rendered substantially free of coliform and pathogenic bacteria.
Claim 3
Dependent Claim
10 words
The method of claim 1 wherein the carbohydrate is lactose.
Claim 4
Dependent Claim
11 words
The method of claim 1 wherein the Lactobacillus is L. plantarum.
Claim 5
Dependent Claim
17 words
The method of claim 1 which includes maintaining the manure at a temperature between about 5°-53° C.
Claim 6
Dependent Claim
16 words
The method of claim 1 which includes maintaining the temperature of the manure between 32°-35° C.
Claim 7
Dependent Claim
16 words
The method of claim 1 wherein the Lactobacillus is L. plantarum and the carbohydrate is lactose.
Claim 8
Dependent Claim
47 words
The method of claim 1 wherein the bacteria is selected from the group consisting of L. acidophilus, L. bulgaricus, L. casei, L. coryniformis, L. delbruckii, L. helveticus, L. lactis, L. leichmannii, L. plantarum, L. thermophilus, L. xylosus, L. brevis, L. buchneri, L. coprophilus, L. fermentum, L. viridescens.
Claim 9
Dependent Claim
11 words
The method of claim 7 wherein the bacteria is L. casei.
Claim 10
Dependent Claim
38 words
The method of claim 1 wherein the carbohydrate is selected from the group consisting of amygdalin, arabinose, cellobiose, esculin, fructose, glactose, glucose, gluconate, lactose, maltose, mannitol, mannose, melezitose, melibiose, raffinose, rhamnose, ribosse, salicin, sorbitol, sucrose, trehalose, and xylose.
Claim 11
Dependent Claim
10 words
The method of claim 9 wherein the carbohydrate is glucose.
Claim 12
Dependent Claim
51 words
The method of claim 1 wherein the carbohydrate is in industrial waste and which includes admixing the industrial waste having a BOD content of from 200 to 34,000 mg/L with the BOD based on the fermentable carbohydrate in the waste which is a food for the bacteria inoculated in the manure.
Claim 13
Dependent Claim
25 words
The method of claim 1 which includes contacting the stabilized manure with ammonia in an amount sufficient to convert the lactic acid to ammonium lactate.
Claim 14
Dependent Claim
21 words
The method of claim 12 which includes maintaining the pH of the manure between 4.8 to 5.5 while contacted with ammonia.
Claim 15
Dependent Claim
16 words
The method of claim 1 wherein the bacteria is L. casei and the carbohydrate is glucose.
Claim 16
Dependent Claim
16 words
The method of claim 1 wherein the bacteria is L. plantarum and the carbohydrate is dextrose.
Claim 17
Dependent Claim
16 words
The method of claim 1 wherein the bacteria is L. casei and the carbohydrate is dextrose.
Claim 18
Independent Claim
63 words
A method for the treatment of industrial waste which waste has a BOD content of from 200-34,000 mg/l, the BOD based on the fermentable carbohydrate in the waste and which carbohydrate is a food for a bacteria which consists of: inoculating the waste with Lactobacillus; and supporting the growth of the bacteria until the pH of the waste is between 3.8 to 4.2.
Claim 19
Independent Claim
63 words
A method for the treatment of industrial waste which waste has a BOD content of from 200-34,000 mg/l, the BOD based on the fermentable carbohydrate in the waste and which carbohydrate is a food for a bacteria which consists of: inoculating the waste with Lactobacillus; and supporting the growth of the bacteria until the pH of the waste is between 3.8 to 4.2.
