Claims
- 1. An animal feed supplement derived from the fermentation broth of Coryneform bacteria, comprising:
(a) L-lysine or a salt of L-lysine; and (b) from 0-100% of the biomass formed during the fermentation of said Coryneform bacteria; and and wherein said animal feed supplement is in the form of an aqueous composition at a pH of greater than 4 and less than 5.
- 2. The animal feed supplement of claim 12, wherein said L-lysine or salt of L-lysine is present at a concentration of 18-35 weight percent (calculated on the basis of lysine base).
- 3. The animal feed supplement of either claim 1 or claim 2, further comprising greater than 50% of the other dissolved and suspended constituents of said fermentation broth.
- 4. An animal feed supplement derived from the fermentation broth of Coryneform bacteria, comprising;
(a) L-lysine or salts of L-lysine at a concentration of 18-35 weight percent (as lysine base); (b) from 0-100% of the biomass formed during the fermentation of said Coryneform bacteria; and (c) greater than 50% of the other dissolved and suspended constituents of said fermentation broth; and wherein said animal feed supplement is in the form of an aqueous composition at a pH of greater than 4 and less than 5.
- 5. The animal feed supplement of claim 4, wherein said animal feed supplement consists of:
(a) L-lysine or salts of L-lysine at a concentration of 18-35 weight percent (as lysine base): (b) from 0-100% of the biomass formed during the fermentation of said Coryneform bacteria; and (c) greater than 50% of the other dissolved and suspended constituents of said fermentation broth; and wherein said animal feed supplement is in the form of an aqueous composition at a pH of greater than 4 and less than 5.
- 6. The animal feed supplement of any one of claims 1, 4 or 5, wherein said animal feed supplement comprises 50-100% of the biomass formed during the fermentation of said Coryneform bacteria.
- 7. The animal feed supplement of any one of claims 1, 4 or 5, wherein said animal feed supplement comprises 90-100% of the biomass formed during the fermentation of said Coryneform bacteria.
- 8. A process of producing an aqueous animal feed additive containing lysine or salts of lysine from a fermentation broth comprising the steps of:
(a) producing an L-lysine-containing broth by the fermentation of Coryneform bacteria; (b) adjusting the pH of the broth to a value of greater than 4 and less than 5.; and (c) concentrating the broth obtained under vacuum; wherein the order of steps (b) and (c) is optional.
- 9. The process of claim 8, further comprising separating the biomass from the fermentation broth of step (a).
- 10. The process of either claim 8 or 9, further comprising achieving a desired concentration in said feed additive by the addition of L-lysine.
- 11. A method of supplementing animal feed, comprising adding the animal feed supplement of any one of claims 1, 4 or 5.
