Abstract

Claims (30)

1 . A method comprising:

separating with a separation device a fractionated stillage stream to provide a heavy phase with suspended solids stream and a light emulsion phase stream;

fermenting with a fermentation vessel at least a portion of the heavy phase with suspended solids stream and an organism to provide a fermentation mixture comprising at least the portion of the heavy phase with suspended solids stream and the organism;

wherein the fermenting converts a carbon source of the fermentation mixture to generate a feed product; and

drying the feed product to provide a dried feed product, wherein the dried feed product has an amino acid content of lysine of from about 1% to about 9% dry basis.

2 . The method of claim 1 , wherein the fractionated stillage stream is from about 3% to about 14% by weight of total solids.

3 . The method of claim 1 , wherein the organism comprises at least one of Candida utilis, Saccharomyces cerevisiae, Pichia stipitis, Pichia pastoris, Escherichia coli, Kluyveromyces marxianus , Corynobacterium lilim, and Corynobacterium glutamicum.

4 . A method comprising:

separating with a separation device a fractionated stillage stream to provide a heavy phase with suspended solids stream and a light emulsion phase stream;

fermenting with a fermentation vessel at least a portion of the heavy phase with suspended solids stream and an organism to provide a fermentation mixture comprising at least the portion of the heavy phase with suspended solids stream and the organism;

wherein the fermenting converts a carbon source of the fermentation mixture to generate a feed product, and wherein a concentration of the organism in the fermentation mixture is from about 1% to about 30% by volume.

5 . The method of claim 1 , wherein the fermentation mixture further comprises a media preparation for the organism, wherein the media preparation comprises nitrogen sources, urea, ammonia, ammonia salts, a sterilizer, or a portion of the fractionated stillage stream.

6 . The method of claim 1 , wherein the separation device comprises at least one of a sedicanter centrifuge, a decanter centrifuge, a disk stack centrifuge, a cyclone, a hydrocyclone, and a settling tank.

7 . The method of claim 1 , wherein the feed product comprises a protein content of from about 30% to about 50% dry basis.

8 . The method of claim 1 , wherein the dried feed product comprises an amino acid content of methionine of from about 0.21% to about 0.46% dry basis.

9 . A method for separating components in a fractionated stillage stream, the method comprising:

separating with a first separation device the fractionated stillage stream to provide a heavy phase with suspended solids stream and a light emulsion phase stream;

fermenting with a fermentation vessel at least a portion of the heavy phase with suspended solids stream and an organism to provide a fermentation mixture comprising at least the portion of the heavy phase with suspended solids stream and the organism;

wherein the fermenting converts a carbon source of the fermentation mixture to a biomass; and

separating with a second separation device the fermentation mixture to provide a separated liquids stream and a separated solids stream that includes at least a portion of the biomass,

wherein the separated solids stream forms at least a part of a feed product.

10 . The method of claim 9 , wherein the fractionated stillage stream has about 3% to about 14% by weight of total solids.

11 . The method of claim 9 , wherein the fermentation mixture further comprises a media preparation for the organism, wherein the media preparation comprises nitrogen sources, urea, ammonia, ammonia salts, a sterilizer, or a portion of the fractionated stillage stream.

12 . The method of claim 9 , wherein the organism comprises at least one of Candida utilis, Saccharomyces cerevisiae, Pichia stipitis, Pichia pastoris, Escherichia coli, Kluyveromyces marxianus , Corynobacterium lilim, and Corynobacterium glutamicum.

13 . The method of claim 9 , wherein a concentration of the organism in the fermentation mixture is from about 1% to about 30% by volume.

14 . The method of claim 9 , wherein the second separation device comprises at least one of a sedicanter centrifuge, a decanter centrifuge, a disk stack centrifuge, a cyclone, a hydrocyclone, and a settling tank.

15 . The method of claim 9 , wherein the feed product comprises a protein content of from about 30% to about 50% dry basis.

16 . The method of claim 9 , wherein the feed product comprises an amino acid content of methionine of from about 0.21% to about 0.46% dry basis.

17 . The method of claim 9 , wherein the feed product comprises an amino acid content of lysine of from about 1% to about 9% dry basis.

18 . The method of claim 9 , further comprising drying the feed product to provide a dried feed product.
