This study proposes to verify the efficiency of the treatment of corn straw with different ILs when increasing the fermentable sugars content. Therefore, the alkaline pulping process of the straw was carried out, with lignin contents of 8.30% and 3.20% and holocellulose of 66.79% and 95.26% in raw and pulp straw, respectively, besides the synthesis and characterization of the sec-butylammonium acetate, sec-butylammonium lactate, n-butylammonium acetate and n-butylammonium lactate. Afterward, the treatment of the raw and pulped straw was carried out with the ILs and subsequent enzymatic hydrolysis. A glucose mass ratio of up to 17.57% was verified in the pulp straw and treated with n-butylammonium acetate, against, 3.98% in the only pulped straw and an increase of up to 90.7% in the mass ratio of fermentable sugars in the treated straw compared to the untreated straw. This efficiency is greater when using ionic liquids with the n-butylammonium cation.Downloads
