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.
Claims15
An animal food product comprising effective amounts of:
- (i) a comminuted recalcitrance reduced feedstock in densified form suitable for ingestion by an animal, and combined with
- (ii) at least one isolated enzyme,
- wherein the feedstock is selected from the group of plant products consisting of lignocellulosic plant materials, cellulosic waste materials, lignocellulosic waste materials, and mixtures thereof,
- wherein the comminuted recalcitrance reduced feedstock is obtained by treating a comminuted feedstock with an electron beam irradiation dosage of at least 5 Mrad under conditions sufficient to reduce the recalcitrance of the comminuted feedstock, and
- wherein the electron beam irradiation reduces the average molecular weight of the comminuted feedstock from 200-320 kD to 10-20 kD.

A method of making an animal food product, the method comprising:
- (a) treating a comminuted material obtained from a collected feedstock,
- wherein the feedstock is selected from the group of plant products consisting of lignocellulosic plant materials, cellulosic waste materials, lignocellulosic waste materials, and mixtures thereof,
- wherein the treating comprises irradiating the comminuted material with an electron beam radiation dosage of at least 5 Mrad under conditions sufficient to reduce the recalcitrance of the comminuted material, and
- wherein the electron beam irradiation reduces the average molecular weight of the comminuted material from 200-320 kD to 10-20 kD;
- and
- (b) combining an effective amount of the treated material of step (a) with an effective amount of an isolated enzyme to obtain said animal food product.
