Abstract

The present invention provides compositions and methods designed to increase value output of a fermentation reaction. In particular, the present invention provides a business method of increasing value output of a fermentation plant. The present invention also provides a modified fermentation residual of higher commercial value. Also provided in the present invention are complete animal feeds, nutritional supplements comprising the subject ferment residuals. Further provided by the present invention is a method of performing fermentation, a modified fermentative microorganism and a genetic vehicle for modifying such microoganism.

Claims

1. A business method of increasing value output of a fermentation plant, comprising

a) performing a fermentation reaction with the use of a modified microorganism;

and

b) marketing or selling one or more of the products of the fermentation reaction comprising said modified microorganism.

3. The business method of claim 1 or 2, wherein fermentation reaction is anaerobic.

4. The business method of claim 1 or 2, wherein the fermentation is aerobic.

5. The business method of claim 1 or 2, wherein the carbon-containing starting material is carbohydrate.

6. The business method of claim 1 or 2, wherein the carbon-containing starting material is selected from the group consisting of oat, wheat, corn, barley, rice, rye, millo, millet, sorghum, potato, and sugar cane.

7. The business method of claim 1 or 2, wherein the fermentation reaction produces an alcohol.

8. The business method of claim 1 or 2, wherein the alcohol is selected from the group consisting of methanol, propanol, and butanol.

9. The business method of claim 1 or 2, wherein the alcohol is ethanol.

10. The business method of claim 1 or 2, wherein the modified microorganism is eukaryotic.

11. The business method of claim 1 or 2, wherein the microorganism is prokaryotic.

12. The business method of claim 1 or 2, wherein the microorganism is yeast.

13. The business method of claim 1 or 2, wherein the microorganism is bacterium.

14. The business method of claim 1 or 2, wherein the modified microorganism is characterized in that whose nutritional content increases by a greater extent than that of an unmodified corresponding microorganism when used in a fermentation reaction, provided with the proviso that if the nutritional content increases due to an increase in at least one essential amino acid, then the at least one essential amino acid is not histidine.

15. The business method of claim 1 or 2, wherein the modified microorganism comprises an exogenous sequence encoding a polypeptide comprising at least one essential amino acid, wherein expression of the exogenous sequence is under the control of a glucose suppressor operon.

16. The business method of claim 1 or 2, wherein the modified microorganism comprises an exogenous sequence encoding a polypeptide comprising at least one essential amino acid, wherein expression of the exogenous sequence is induced when the fermentation reaction has achieved at least about 50% completion.

17. The business method of claim 1 wherein the product is a fermentation product or a fermentation residual.

19. The business method of claim 1 or 2 wherein the increase in value output is achieved without substantially decreasing the amount of fermentation products that are produced by the fermentation reaction.

20. The business method of claim 1 or 2 wherein the modified microorganism utilizes a carbon-containing starting material to produce an alcohol or an alkane in a fermentation reaction, wherein said microorganism also produces a nutrient subsequent to the initiation of alcohol or alkane production.

21. The business method of claim 20, wherein the nutrient is selected from the group consisting of a protein, hormone, amino acid, vitamin, and lipid.

2. A business method of increasing value output of a fermentation plant, comprising performing a fermentation reaction using carbon-containing material in the presence of a modified microorganism to yield fermentation residual that has a higher commercial value than if the fermentation reaction were performed in the absence of the modified microorganisms.

18. The business method of claim 2 wherein the fermentation residual has an enhanced nutritional content.
