Activities of crude enzymes from the complementary strains CΔPoxCxrA, CΔPoxCxrB and CΔPoxNsdD after a shift from glucose to Avicel. Crude enzymes were produced by fungal strains grown in 2% (w/v) Avicel as the sole carbon source for 4 days after the shift. **P ≤ 0.01 between the complementary strains and the regulatory gene mutants, assessed with Student’s t test. *P ≤ 0.05 between CΔPoxCxrB and ΔPoxCxrB assessed with Student’s t test. a Filter-paper cellulase (FPase) activity. b Endo-glucanase (CMCase) activity. c p-Nitrophenyl-β-cellobiosidase (pNPCase) activity. d p-Nitrophenyl-β-glucopyranosidase (pNPGase) activity. e Xylanase activity
