Figure 5From: Bioconversion of paper sludge to biofuel by simultaneous saccharification and fermentation using a cellulase of paper sludge origin and thermotolerant Saccharomyces cerevisiaeTJ14Confirmation of optimized ethanol production in simultaneous saccharification and fermentation (SSF). Symbols: open triangles = reducing sugars (RS); open circles = glucose; open squares = ethanol; closed squares = Ye/hex. Error bars denote 5% error of three repeated experiments.Back to article page
