Hydrolysis of cellulose ester
WebHowever, this treatment was not enough to allow the enzyme hydrolysis. A second step of treatment with NaOH 3.0% at 120 °C without agitation for 60 min led to a material with 75.0% of cellulose and 25.0% of lignin. However, the lowest glucose yield (80.86% and 32.26 g L−1 of glucose) was obtained after the enzyme hydrolysis of this material.
