Abstract

The present invention relates to a novel liquid or crystalline methionine composition, obtained by means of biomass bioconversion by means of microorganisms that are suitable for producing methionine.

First claim

The invention claimed is:

1. A feed additive for feeding animals comprising a methionine composition resulting from a fermentation process, said methionine composition comprising:
from 60 to 95% by weight of methionine;
from 0.05 to 2.5% by weight of N-acetylmethionine; and
from 0.05 to 3.5% by weight of isoleucine.

2. The feed additive of claim 1 , said methionine composition further comprising:
from 1.0 to 6.0% by weight of amino acids other than methionine, N-acetylmethionine and isoleucine;
from 0.1 to 2% by weight of total sugars; and
from 0.05 to 2.5% by weight of lipids.

3. The feed additive of claim 1 , wherein said additive is a liquid.

4. The feed additive of claim 1 , wherein said methionine composition comprises:
from 60 to 80% by weight of methionine;
from 0.5 to 2.0% by weight of N-acetylmethionine; and
from 0.20 to 1.5% by weight isoleucine.

5. The feed additive of claim 2 , said methionine composition further comprising:
from 2 to 6% by weight of amino acids other than methionine, N-acetylmethionine and isoleucine;
from 0.5 to 2% by weight of total sugars; and
from 0.05 to 2.5% by weight of lipids.

6. The feed additive of claim 1 , said methionine composition comprising:
from 70 to 90% by weight of methionine;
from 0.05 to 2.5% by weight of N-acetylmethionine; and
from 0.10 to 1.0% by weight of isoleucine.

7. The feed additive of claim 2 , said methionine composition further comprising:
from 2 to 6% by weight of amino acids other than methionine, N-acetylmethionine and isoleucine;
from 0.25 to 2% by weight of total sugars; and
from 0.05 to 2.5% by weight of lipids.

8. The feed additive of claim 2 , wherein said additive is a liquid.

9. The feed additive of claim 1 , said methionine composition comprising:
from 80 to 95% by weight of methionine;
from 0.05 to 0.5% by weight of N-acetylmethionine; and
from 0.05 to 5.0% by weight of isoleucine.

10. The feed additive of claim 2 , said methionine composition further comprising:
from 1.0 to 5.0% by weight of amino acids other than methionine, N-acetylmethionine and isoleucine;
from 0.1 to 1.5% by weight of total sugars, and less than 0.3% by weight of lipids.

11. A process for preparing the feed additive of claim 1 comprising:
clarifying fermentation medium in which a microorganism that has been modified to produce methionine has been cultured and removing insoluble and soluble organic impurities from said fermentation medium to obtain a liquid crude composition; and
recovering the feed additive.

12. The process for preparing a feed additive of claim 11 , wherein the liquid crude composition further comprises:
from 2 to 6% by weight of amino acids other than methionine, N-acetylmethionine and isoleucine;
from 0.1 to 2% by weight of total sugars; and
from 0.05 to 2.5% by weight of lipids.

13. The process for preparing a feed additive of claim 11 , said process further comprising:
demineralizing the liquid crude solution in order to remove cations and anions from said fermentation medium to obtain a demineralized liquid crude composition comprising:
from 70 to 90% by weight of methionine;
from 0.05 to 2.5% by weight of N-acetylmethionine; and
from 0.10 to 1.0% by weight of isoleucine.

14. The process for preparing a feed additive of claim 13 , said demineralized liquid crude composition further comprising:
from 2 to 6% by weight of amino acids other than methionine, N-acetylmethionine and isoleucine;
from 0.25 to 2% by weight of total sugars; and
from 0.05 to 2.5% by weight of lipids.

15. The process for preparing a feed additive of claim 11 , wherein the feed additive is liquid and said process does not comprise a crystallization step.

16. The process for preparing a feed additive of claim 11 , further comprising:
crystallizing solid crude methionine from an optionally demineralized, liquid crude composition.

17. The process for preparing a feed additive of claim 16 , said method further comprising:
separating, optionally washing, and optionally milling methionine crystals in order to obtain a solid crude composition.

18. The process for preparing a feed additive of claim 16 , wherein said solid crude composition comprises:
from 80 to 95% by weight of methionine;
from 0.05 to 0.5% by weight of N-acetylmethionine; and
from 0.05 to 5.0% by weight of isoleucine.

19. The process for preparing a feed additive of claim 18 , wherein the solid crude methionine composition further comprises:
from 1.0 to 5.0% by weight of amino acids other than methionine, N-acetylmethionine and isoleucine;
from 0.1 to 1.5% by weight of total sugars; and
less than 0.3% by weight of lipids.
