Abstract: A method of obtaining ethanol from a lignocellulosic biomass comprises delignification of a lignocellulosic biomass using a modified Caro's acid. Next a solid portion of the delignification reaction mixture is recovered wherein the solid portion comprises a substantially hemicellulose-free cellulosic component which includes at most, up to 15% w/w hemicellulose. Next, the recovered solid portion of the resulting reaction mixture is exposed to an enzyme mix comprising cellulase enzymes to create a saccharification system that breaks down the cellulose into a saccharified composition such as oligosaccharides. The saccharified composition is then fed to an organism, such as yeast, with the ability to ferment sugars into ethanol.
