1-30. (canceled)
A method of producing one or more fermentation end-products from a biomass composition comprising lignocellulose, the method comprising:
- (a) pretreating the biomass composition to produce a pretreated biomass composition, wherein the pretreating comprises:
- (i) hydration of the biomass composition to produce a hydrated biomass composition,
- (ii) mechanical size reduction of the hydrated biomass composition to produce solid particles that are less than 10 mm in size, wherein the mechanical size reduction comprises cutting or shearing, and
- (iii) heating of the hydrated biomass composition, thereby producing a mixture of a first population of saccharide polymers and the solid particles;
- and
- (iv) subjecting the mixture of the first population of saccharide polymers and the solid particles to steam explosion, thereby producing the pretreated biomass composition;
- and
- (b) hydrolyzing and fermenting the pretreated biomass composition with one or more microorganisms for a time sufficient to produce the one or more fermentation end-products.
