Abstract
The present invention relates to compositions and methods for the conversion of lignocellulosic material to fermentable sugars and to products produced therefrom (e.g., ethanol, foodstuffs, etc.). In particular, the invention provides lignocellulose-degrading compositions (e.g., generated via incubation of microbes with lignocellulosic priming feedstock in solid-state fermentation format) and methods of using the same (e.g., in saccharification and/or hydrolysis steps (e.g., on ethanologenic feedstock) and as food or feed additives).
Claims21
A composition for generation of ethanol from lignocellulosic feedstock comprising a lignocellulosic feedstock degradation composition comprising a lignocellulosic priming feedstock incubated with at least one lignocellulose-degrading microbe.
A composition for use as an animal feed supplement, the composition made by a process comprising solid-state fermentation of lignocellulosic feedstock with at least one lignocellulose-degrading microbe under conditions sufficient to yield lignocellulosic feedstock properties selected from the group consisting of increased digestible protein, increased level of bioavailable phosphorous, and decreased fiber content.
A method of producing ethanol from a ethanologenic feedstock comprising:
- 1) providing:
- a) a lignocellulose-degrading composition;
- b) an ethanologenic feedstock comprising a lignocellulosic component;
- and
- 2) incubating the ethanologenic feed stock with the lignocellulose-degrading composition.
A method for the production of ethanol from lignocellulosic feedstock, comprising:
- i) providing lignocellulosic priming feedstock capable of utilization as substrate by at least one lignocellulose-degrading microbe;
- ii) incubating the lignocellulose-degrading microbe on the lignocellulosic priming feedstock under conditions sufficient to promote formation of at least one lignocellulose-degrading composition;
- iii) providing ethanologenic feedstock capable of utilization as substrate by an ethanologenic microbe in a saccharification step;
- iv) mixing the lignocellulose-degrading composition with the ethanologic feedstock under conditions sufficient to promote saccharification of the ethanologenic feedstock;
- and
- v) conducting ethanologenic fermentation on the ethanologenic feedstock.
