Figure 4From: Production and effect of aldonic acids during enzymatic hydrolysis of lignocellulose at high dry matter contentEffect of glucose and gluconic acid on β-glucosidase activity. Level of β-glucosidase activity in Novozym 188 (●) and Cellic CTec2 (▲) as function of gluconic acid (dotted line), and glucose (solid line) concentration. The activity was measured using p-nitrophenyl-β- D-glucopyranoside as substrate. The activity without the presence of glucose or gluconic acid was set to 100%.Back to article page
