ABSTRACT:
A synergistic combination of high-shear mechanical disruption and alkali pretreatment in a high solids reaction mixture constitutes a significant improvement in the alkaline peroxide treatment of lignocellulosic materials. The simultaneous application of these conditions greatly reduces the amounts of reagents otherwise required, and also eliminates the waste stream of liquid byproducts. Suitable sources of substrate treatable by this process include nonwoody plant parts, crop residues, and agricultural byproducts. The products of this treatment are nontoxic and characterized by high cellulose availability. These products are thereby useful as carbohydrate sources in ruminant feeds, as microbial feedstocks, and as sources of dietary fiber for humans and other monogastrics.
