Cellulase and xylanase activities of the strains under various culture conditions. A, Glucose consumption. The strains were cultured in cellulose- and glucose-containing medium. Initial cellulose and glucose concentrations were 10 and 40 g/L (circles), 25 and 25 g/L (triangles), and 40 and 10 g/L (squares), respectively. B, FPase and xylanase activities of the strains under various culture conditions. Initial cellulose and glucose concentrations were 50 and 0 g/L (5:0), 40 and 10 g/L (4:1), 25 and 25 g/L (2.5:2.5), and 10 and 40 g/L (1:4), respectively. Initial xylan concentration was 50 g/L. Black bars, FPase; white bars, xylanase. Data are presented as the mean of three experiments.
