Abstract
Official abstract text for this publication.
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
Opening claim text (preview).
The invention claimed is: 1. A method comprising: milling a lignocellulosic material to a particle size that can pass through a screen having an average pore opening of less than 0.79 mm; treating the milled lignocellulosic material with a beam of electrons, wherein the electrons have an energy level of about 0.8 MeV to 1.8 MeV and wherein the treating is performed to a dose of about 2 Mrad to 50 Mrad; and combining the treated material with Alcaligenes eutrophus bacteria, which uses the treated material as a substrate to produce polyhydroxyalkanoate (PHA). 2. The method of claim 1 , wherein the lignocellulosic material comprises paper, paper products, paper waste, wood, particle board, sawdust, agricultural waste, sewage, silage, grasses, rice hulls, bagasse, cotton, jute, flax, bamboo, sisal, abaca, straw, corn cobs, corn stover, switchgrass, alfalfa, hay, rice hulls, coconut hair, cotton, cassava, and mixtures thereof. 3. The method of claim 1 , wherein the treated material is combined with Alcaligenes eutrophus bacteria using a batch-fed fermentation process. 4. The method of claim 1 , further comprising a step selected from sonication, oxidation, pyrolyzing, and steam-explosion. 5. The method of claim 1 , further comprising adding a nutrient medium when the treated material is combined with Alcaligenes eutrophus bacteria. 6. The method of claim 1 , wherein the lignocellulosic material is cooled before, during or after exposure to the beam of electrons.
