     developing feedstock-independent biomass pretreatment would be vital to second generation biorefineries that would fully utilize diverse non-food lignocellulosic biomass resources, decrease transportation costs of low energy density feedstock, and conserve natural biodiversity. cellulose solvent- and organic solvent-based lignocellulose fractionation (coslif) was applied to a variety of feedstocks, including miscanthus, poplar, their mixture, bagasse, wheat straw, and rice straw. although non-pretreated biomass samples exhibited a large variation in enzymatic digestibility, the coslif-pretreated biomass samples exhibited similar high enzymatic glucan digestibilities and fast hydrolysis rates. glucan digestibilities of most pretreated feedstocks were ∼93% at five filter paper units per gram of glucan. the overall glucose and xylose yields for the miscanthus:poplar mixture at a weight ratio of 1:2 were 93% and 85%, respectively. these results suggested that coslif could be regarded as a feedstock-independent pretreatment suitable for processing diverse feedstocks by adjusting pretreatment residence time only.
