Enzyme activity in WT, Δ3βG, and Δ3βGΔcre strains after induction with cellobiose or Avicel. (A) The 24 h induced supernatant activity (from Fig. S8 A, B, and D) toward Avicel. Cellulase activity of culture supernatant from Δ3βG (□) and Δ3βGΔcre (◊) strains when induced with cellobiose for 24 h compared to culture supernatants from WT grown on Avicel for 5 d (▵). (B) Breakdown of cellobiose (light gray) and glucose (dark gray) produced in the Avicel hydrolysis assay (from A) after 36 h. Error bars are 1 SD.
