Abstract

The invention relates to a method for producing an organic compound from manure, including the steps of:

i) concentrating the manure to form a vapor;

ii) condensing said vapor to form a condensate;

iii) adding to said condensate micro-organisms which are capable of producing the organic compound; and

iv) separating from the condensate the organic compound produced by the micro-organisms.

These micro-organisms comprise species of the genera Arthrobacter, Brevibacterium, Corynebacterium, Bacillus, Escherichia, Microbacterium, Micrococcus and Pseudomonas.

Claims

1. A method for producing an amino acid compound selected from the group consisting of L-lysine and L-methionine from manure, comprising:

i) concentrating the manure to form a vapor;

ii) condensing said vapor to form a condensate;

iii) adding to said condensate specific-amino acid-organic-compound-producing microorganisms are selected from the group consisting of the species of the genera Arthrobacter, Brevibacterium, Corynebacterium, Bacillus, Escherichia, Microbacterium, Micrococcus and Pseudomonas; and

iv) separating from the condensate the specific organic compound produced by said specific-amino acid-organic-compound-producing-microorganisms.

2. The method according to claim 1 wherein during said step of condensing said vapor the manure is condensed fractionally to a first ammonia-rich condensate and a second condensate rich in organic compounds.

3. The method according to claim 2 wherein the manure is concentrated at a pH of 5-7.

4. The method according to claim 1 wherein the condensate of step ii) is concentrated.

5. The method as claimed in claim 4 wherein additives are added to the condensate of step ii).

6. The method according to claim 5 wherein said additives are selected from the group consisting of vitamins, metals, minerals and agricultural waste.

7. Method according to claim 1 wherein the condensate of step ii) contains 5-20 g/l of carbon source and 0.5-5 g/l nitrogen source.
