    Abstract: One-pot processes to separate lignin from a lignocellulosic feedstock include providing a vessel; providing a lignocellulosic feedstock; providing an aqueous composition comprising an acid, a modifying agent comprising a substituted aromatic compound, and a peroxide; and exposing the lignocellulosic feedstock to the composition in the vessel for a period of time sufficient to remove at least 80% of the lignin present in the lignocellulosic feedstock.

    Abstract: A process to obtain glucose from a pretreated lignocellulosic biomass comprises providing a lignocellulosic biomass and contacting said lignocellulosic biomass to a modified Caro's acid composition for a period of time necessary to remove more than 98.5% of the lignin present in the lignocellulosic biomass and thus obtaining a solid stream and a liquid stream. The solid stream is exposed to an enzyme blend to produce a hydrolysate comprising sugars obtained from the hydrolysis of cellulose and hemicellulose. Optionally, the hydrolysate may be fermented to produce value-added products.

    Abstract: A process to increase the amount of methane produced from a bio-digester comprises providing a digester to receive a feed and to capture a biogas composition resulting from bio-digestion. Organic material is added to the digester along with at least one inoculum capable of converting a portion of the organic material into methane under anaerobic conditions. A biomass is provided that is substantially free of lignin in an amount that ranges between 0.1 to 5% w/w of the total feed, the biomass further having another organic material. The biomass is added to the digester. Sufficient time is allowed for the digester to degrade the biomass and the organic material to yield a biogas composition that includes methane. Optionally, the biomass that is substantially free of lignin is added in an amount that ranges between 0.1 to 5% w/w of the total feed of the biomass having the other organic material.

    Abstract: Method of delignification of plant material, said method comprising: providing said plant material comprising cellulose fibres and lignin; exposing said plant material requiring to a composition comprising: an acid; a modifying agent selected from the group consisting of: sulfamic acid; imidazole; N-alkylimidazole derivative; taurine; a taurine derivative; a taurine-related compound; alkylsulfonic acid; arylsulfonic acid; triethanolamine; and combinations thereof; a metal oxide; and a peroxide; adding an organic solvent to the resulting mixture; allowing a delignification reaction to occur for a period of time sufficient to remove at least 80% of the lignin present on said plant material.

    Abstract: One-pot processes to separate lignin from a lignocellulosic feedstock include providing a vessel; providing a lignocellulosic feedstock; providing a composition comprising an acid, a modifying agent comprising an alkanesulfonic acid, and a peroxide; and exposing the lignocellulosic feedstock to the composition in the vessel for a period of time sufficient to remove at least 80% of the lignin present in the lignocellulosic feedstock. In some instances, such one-pot process can further include removing a liquid phase comprising dissolved lignin fragments from a solid phase comprising cellulose fibres.
