Fig. 1: Identification of the high antioxidant capacity of the Tg strain.

A Colony morphology of Tg (T. guizhouense), Gv29-8 (T. virens), CBS226.95 (T. harzianum), and Qm6a (T. reesei) cultivated on GSM plates supplemented with 0, 5, 10, 20, and 40 mM H₂O₂ at 25 °C for 42 h in the darkness. B The relative inhibition rates of mycelial growth of Tg, Gv29-8, CBS226.95 and Qm6a on GSM plates in the presence of 0, 5, 10, 20, and 40 mM H₂O₂ cultivated for 42 h (n = 6 biologically independent samples). C Colony morphology of the Tg WT, ΔTgap1, ΔTgskn7, ΔTgatf1, and ΔTgatf2 strains incubated on GSM plates supplemented with 0, 5, 10, 20, and 40 mM H₂O₂ at 25 °C for 42 h in the darkness. The deletion mutant of Tgatf1 was retrieved from Li et al.⁸⁰. D The relative inhibition rates of mycelial growth of Tg WT, ΔTgap1, ΔTgskn7, ΔTgatf1, and ΔTgatf2 strains in the presence of 0, 5, 10, 20, and 40 mM H₂O₂ cultivated for 42 h (n = 6). The bars show the average values for each factor, and the error bars represent the 1.96 * Standard Error for the Sample Mean. Different lowercase letters (a, b, c, d) indicate statistically significant differences at P < 0.05 in the growth of selected strains under the same concentration, based on one-way ANOVA followed by Tukey’s HSD test. The letters were assigned in descending order of sample means. Strains sharing the same letter were not significantly different. Exact P-values were provided in Supplementary Data 6.
