A. nidulans growth in the presence of xylose or xylose plus glucose. (A) Enzymatic activity of endo-1,4-β-xylanase in the culture supernatant in the presence of xylose (X) or xylose plus glucose (XG) after 6 h, 12 h and 24 h incubation at 37°C. One unit of enzyme activity is defined as the amount of enzyme required to release 1 μmol of D-xylose reducing-sugar equivalents from arabinoxylan, at pH 4.5 per minute at 40°C. Error bars represent the standard deviation for three biological replicates; *significant difference in the P-value (<0.01, one-way analysis of variance (anova) and Newman-Keuls test) between X and XG-grown cultures for each strain. (B) Xylose concentrations in the supernatant of A. nidulans wild-type and creAd30 cultures grown in the presence of xylose (X) or xylose plus glucose (XG) for 6 h, 12 h, and 24 h at 37°C. (C) Glucose concentrations in the supernatant of A. nidulans wild-type and creAd30 cultures grown in the presence of xylose or xylose plus glucose for 6 h, 12 h and 24 h at 37°C. Error bars represent the standard deviation for three biological replicates; *significant difference in the P-value (<0.01, one-way Anova and Newman-Keuls test) between X and XG-grown cultures for each strain.
