    Abstract: Methods of producing clean (e.g., low sulfur and metal ion content, and free of fermentation inhibitors) sugar and lignin-rich streams, and downstream conversion products, from lignocellulosic biomass, may include obtaining non-chemically pretreated, milled lignocellulosic biomass, reacting the milled lignocellulosic biomass with an enzymatic agent to produce a slurry that includes converted monomeric lignocellulosic sugars and lignin-rich residuals, and separating the slurry into a sugar stream that includes the converted monomeric lignocellulosic sugars and a lignin-rich stream that includes the lignin-rich residuals. The sugar stream, not including water, includes at least 75% monomeric lignocellulosic sugar, less than 0.20% sulfur, and less than 3.0% metal ion content, and the lignin-rich stream includes at least 35% lignin and less than 0.50% sulfur. Some methods include producing fermentation products such as alcohols and/or organic acids from the sugar stream, and/or use of the lignin residuals in fuels.

    Abstract: Disclosed herein are materials and structural elements for absorbent articles that incorporate at least one component of a chemiluminescent system configured to produce light upon contact with an aqueous system. This disclosure also relates to absorbent articles that incorporate materials or structural elements. This disclosure also relates to formulations and methods for treating materials or structural elements with one or more components of such a chemiluminescent system. Representative absorbent articles include disposable diapers and adult incontinence products. Representative chemiluminescent systems include bioluminescent systems.
