Activities of crude enzymes from PoxClrB, POX02484 and POX08522 deletion mutants following a shift from glucose to Avicel. Crude enzymes were produced by fungal strains grown in 2.0 % Avicel as the sole carbon source. Enzymatic activity was measured at 3 and 5 days after the shift. The symbols * and ** indicate significant differences (P ≤ 0.05 and P ≤ 0.01, respectively) between the candidate mutants and the parent ΔPoxKu70 strain, as assessed by Student’s t test. ^a FPase, pNPCase, pNPGase activities and CMCase activity from 72 h of induction; ^b Xylanase activity and CMCase activity from 120 h of induction
