Figure 6From: Production and effect of aldonic acids during enzymatic hydrolysis of lignocellulose at high dry matter contentGluconic acid production as function of cellulose conversion. Gluconic acid concentration as function of cellulose conversion using Cellic CTec2 at 33°C (Δ) and 50°C (□) with pretreated wheat straw ( A) and filter paper ( B) as substrate. The enzyme loading was 7.5 FPU/g DM and the solids concentration was 30% WIS of wheat straw and 5% WIS of filter paper. In the case of filter paper 20 mM ascorbic acid was added as external electron donor.Back to article page
