Penetration, cellulose utilization, and oxidative stress of different fungal strains. The WT, ccp1, and Comp fungal strains were generated from Foc TR4 VCG01213/16. a Fungal strains on PDA medium half-covered by cellophane after 7 d of growth at 28 °C. b Fungal strains on cellulose-Congo red medium after 7 d of growth at 28 °C. c Fungal strains on PDA medium with 0.1% H₂O₂ for 7 days (upper), with 0.5% H₂O₂ for 7 days (middle), and with 0.5% H₂O₂ for 30 days (lower) at 28 °C. d Colony diameter of all fungal strains under 0.1 and 0.5% H₂O₂ treatment. The error bars represent SE. Asterisks indicate significantly difference (** P < 0.01)
