Figure 3From: Bioconversion of paper sludge to biofuel by simultaneous saccharification and fermentation using a cellulase of paper sludge origin and thermotolerant Saccharomyces cerevisiaeTJ14Comparison of hydrolysis between cellulase from paper sludge (PS) and commercial Acremozyme cellulase. (A) Reducing sugars (RS) concentration in PS hydrolysate when using cellulase of PS origin (open circles) and commercial cellulase (open triangles). (B) Surface response of the released RS concentration in an enzymatic hydrolysis of PS using cellulase of PS origin. Error bars in (A) denote 5% error of three repeated experiments.Back to article page
