A mild biomass pretreatment for concentrated sugar production
Here we report that γ-valerolactone (GVL), a biomass-derived solvent, can be used to facilitate the mild pretreatment of lignocellulosic biomass. An 80% GVL, 20% water solvent system was used to pretreat hardwood at the mild temperature of 120 °C with an acid loading of 75 mM H2SO4…
