The selectivecatalyticoxidation of monosaccharides was applied to butylxylosides and butylglucosides leading to the formation of bioactive karrikins, molecules that are important in the response to catastrophic fires. Butanosolv processing of biomass provides a co-product stream that contains these starting materials providing relevance to this work in the biorefinery context.

Chemically modified lignins are important for the generation of biomass‐derived materials and as precursors to renewable aromatic monomers. A butanol‐based organosolv pretreatment has been used to convert an abundant agriculturalwaste product, rice husks, into a cellulose pulp and three additional product streams. One of these streams, a butanol‐modified lignin, was oxidized at the γ position to give

The present disclosure is directed, in a first aspect, to the use of inverting beta-xylosidase enzymes to reduce byproduct formation and increase the yield of fermentation products, as well as, in a second aspect, to the use of retaining beta-xylosidase enzymes to improve production of alkyl-beta-xylopyranoside compounds, in a simultaneous saccharification and fermentation reactions.
