Time course of enzyme activity from N. crassa and A. nidulans culture supernatants. (A) CMCase activity of culture supernatants from N. crassa or A. nidulans cultures shifted to either Avicel or sucrose, as measured by cleavage of dye-conjugated CMC. (B) Xylanase activity of culture supernatants from N. crassa or A. nidulans cultures shifted to either Avicel or sucrose, as measured by cleavage of dye-conjugated xylan. (C) Secreted protein in N. crassa or A. nidulans supernatants from cultures shifted to either Avicel or sucrose, as determined by Bradford assay. (D) Cellulase activity, as determined by sugar release from Avicel, of N. crassa or A. nidulans supernatants from cultures shifted to either Avicel or sucrose. (E) Final mycelia dry weights 72 and 96 h after shift of N. crassa and A. nidulans cultures to sucrose or Avicel. Biomass in Avicel cultures was estimated by degrading mycelia and weighing the recalcitrant fraction (Updegraff 1969). (F) Cumulative breakdown of Avicel normalized to final dry weight of cultures. (A–D) All data points normalized to final culture biomass as in (E).
