The researchers explored how ionic liquids could help break down cellulose for biofuel production more efficiently. By using these special liquids to pretreat the cellulose, they made the material easier for enzymes to break down into glucose, a key step in making biofuels. Although the ionic liquids initially inhibited the enzyme activity, they developed a way to increase efficiency and yield by optimizing the enzyme mix. By combining chemical and enzymatic processes, they achieved almost complete conversion of cellulose to glucose in just 5 hours. This method shows promise for improving the production of biofuels from plant biomass.
