  "abstract": "The invention relates to methods for producing a fermentation product from a lignocellulose-containing material comprising: i) pre-treating lignocellulose-containing material; ii) introducing pre-treated lignocellulose-containing material into medium comprising fermentable sugars derived from starch-containing material; ii) fermenting using a fermenting organism.",
  "claims": [
    "1. A method for producing a fermentation product from lignocellulose-containing material, wherein the method comprises: i) pre-treating lignocellulose-containing material; ii) introducing pre-treated lignocellulose-containing material into a medium comprising fermentable sugars derived from starch-containing material; and ii) fermenting using a fermenting organism.",
    "2. The method of claim 1, wherein the starch-containing material and the lignocellulose-containing material are treated in two separate streams before saccharification, fermentation or simultaneous saccharification and fermentation.",
    "3. The method of claim 1, wherein the medium is a starch saccharification medium, starch fermentation medium or starch simultaneous saccharification and fermentation medium.",
    "4. The method of claim 1, wherein the method comprises introducing pre-treated lignocellulose-containing material into a simultaneous saccharification and fermentation medium containing one or more starch-degrading enzymes and optionally a fermenting organism.",
    "5. The method of claim 1, wherein the fermentation is initiated before or after the pre-treated lignocellulose material is introduced into the medium.",
    "6. The method of claim 1, wherein the pre-treated lignocellulose-containing material is hydrolyzed before fermentation or simultaneous saccharification and fermentation.",
    "7. The method of claim 1, wherein solids from the pre-treated lignocellulose-containing material are removed before or during fermentation.",
    "8. The method of claim 1, wherein the pre-treated lignocellulose-containing material, having solids removed, is added during saccharification, fermentation, or simultaneous saccharification and fermentation.",
    "9. The method of claim 1, wherein the pre-treated lignocellulose-containing material is un-detoxified.",
    "10. The method of claim 1, wherein the lignocellulose-containing material has been chemically, mechanical or biologically pre-treated.",
    "11. The method of claim 1, wherein the lignocellulose-containing material has been hydrolyzed by treatment with one or more cellulases or hemicellulases, or a combination thereof.",
    "12. The method of claim 1, wherein the starch-containing material is liquefied gelatinized starch-containing material.",
    "13. The method of claim 1, wherein the liquefied gelatinized starch-containing material is saccharified before or during fermentation.",
    "14. The method of claim 1, wherein the starch-containing material is uncooked starch-containing material.",
    "15. The method of claim 1, wherein the lignocellulose derived material introduced into the fermentation medium is un-washed.",
    "16. A process for producing a fermentation product from a combination of starch-containing material and lignocellulose-containing material comprising the steps of: a) liquefying starch-containing material; b) saccharifying; c) fermenting using a fermenting organism; wherein the pre-treated lignocellulose-containing material is added before or during fermentation.",
    "17. The process of claim 16, wherein saccharification in step (b) and fermentation in step (c) are carried out sequentially or simultaneously.",
    "18. The method of claim 16, wherein the pre-treated lignocellulose-containing material is hydrolyzed before fermentation or simultaneous saccharification and fermentation.",
    "19. The method of claim 16, wherein the starch-containing material and the lignocellulose-containing material are treated in two separate streams before saccharification, fermentation or simultaneous saccharification and fermentation.",
    "20. The process of claim 16, wherein solids from the pre-treated lignocellulose-containing material are removed before fermentation.",
    "21. The process of claim 16, wherein the pre-treated lignocellulose-containing material, having solids removed, is added to saccharification step b), fermentation step c), or simultaneous saccharification and fermentation.",
    "22. The method of claim 21, wherein the pre-treated lignocellulose-containing material is un-detoxified.",
    "23. The process of claim 16, wherein the lignocellulose-containing material has been chemically, mechanically or biologically pre-treated.",
    "24. A process for producing a fermentation product from a combination of starch-containing material and lignocellulose-containing material comprising the steps of: i) saccharifying the starch-containing material at a temperature below the initial gelatinization temperature; ii) fermenting using a fermenting organism; wherein the pre-treated lignocellulose containing material is added before or during fermentation.",
    "25. The process of claim 24, wherein saccharification in step i) and fermentation in step ii) are carried out sequentially or simultaneously.",
    "26. The process of claim 24, wherein the pre-treated lignocellulose-containing material is hydrolyzed before fermentation or simultaneous saccharification and fermentation.",
    "27. The process of claim 24, wherein the starch-containing material and the lignocellulose-containing material are treated in two separate streams before saccharification, fermentation or simultaneous saccharification and fermentation.",
    "28. The process of claim 24, wherein the pre-treated lignocellulose material has further been hydrolyzed by treatment with a cellulase or hemicellulase, or a combination thereof, before fermentation.",
    "29. The process of claim 24, wherein solids from the pre-treated lignocellulose-containing material are removed before fermentation.",
    "30. The process of claim 24, wherein the pre-treated lignocellulose-containing material, having solids removed, are added to saccharification step i), fermentation step ii) or simultaneous saccharification and fermentation.",
    "31. The process of claim 24, wherein the lignocellulose-containing material has been chemically, mechanically or biologically pre-treated.",
    "32. The process of claim 24, wherein one or more carbohydrate-generating enzymes are used during saccharification or simultaneous saccharification and fermentation.",
    "33. The process of claim 24, wherein the lignocellulose-containing material is un-washed.",
    "34. The process of claim 24, wherein the starch-containing material is uncooked granular starch."
