Design of a mediator-based deep eutectic solvent for targeted modulation of the lignin structure for lignin-enhanced multifunctional gels and fermentable sugar

In order to achieve efficient fractionation and valorization of sugarcane bagasse, a p -TsOH-mediated DES was developed by incorporating a small amount of p -toluenesulfonic acid ( p -TsOH) into a mixture of choline chloride (ChCl) and lactic acid (LA).
