Abstract

Biomass (e.g., plant biomass, animal biomass, microbial, and municipal waste biomass) is processed to produce useful products, such as food products and amino acids.

First claim

What is claimed is:

1. A method of making an animal feed, the method comprising: (i) treating a comminuted lignocellulosic biomass with electron beam radiation of greater than 5 Mrad of radiation and at a dosing rate sufficient to produce a recalcitrance reduced lignocellulosic biomass; and (ii) combining said recalcitrance reduced lignocellulosic biomass with a solid additive, thereby producing said animal feed.

2. The method of claim 1 wherein the lignocellulosic biomass comprises corn cobs and/or corn stover.

3. The method of claim 1 wherein the solid additive is selected from a group consisting of an enzyme, microorganism, animal products, antibiotics, nutrients, prebiotics, flavoring agents, coloring agents, preservatives, metabolic modifiers and mixtures thereof.

4. The method of claim 3 wherein the enzyme comprises a multiple enzyme cocktail.

5. The method of claim 3 wherein the enzyme comprises a dried enzyme.

6. The method of claim 3 wherein the enzyme comprises an enzyme requiring activation.

7. The method of claim 3 wherein the enzyme is selected from the group consisting of phytase, cellulase, lactase, lipase, pepsin, catalase, xylanase, pectinase, and mixtures thereof.

8. The method of claim 3 wherein the microorganism is selected from a group consisting of bacteria, yeast, fungi, algae and mixtures thereof.

9. The method of claim 3 wherein the microorganism is selected from a group consisting of Aspergillus niger, Baccillus subtillis, Bifidobacterium animalis, Bifidobacterium, bifidum, Enterococcus faecium, Aspergillus oryzae, Lactobacillus acidophilus, Lactobacillus bulgaricus, Lactobacillus plantarum, Streptococcus lactis , and Saccharomyces cerevisiae.

10. The method of claim 3 wherein the animal product is selected from a group consisting of animal meat, poultry, animal bone, animal fat, animal waste-product, dairy product, marine product, fat, oil and mixtures thereof.

11. The method of claim 3 wherein the antibiotic is selected from a group consisting of tetracyclines, macrolides, fluoroquinolones, streptogramins and mixtures thereof.

12. The method of claim 3 wherein the nutrient is selected from a group consisting of proteins, vitamins, minerals, salts, amino acids, fatty acids and mixtures thereof.

13. The method of claim 1 wherein the solid additive is in the form of pellets, powder, tablets, blocks, particulates, or granules.
