Characterization of the growth and hyphal morphology of Δste20. a Growth of TU-6 and Δste20 strains on minimal medium plates containing different carbon sources. Strains were grown at 30 °C for 3 days. Double-layered Avicel plates were used to evaluate the crystalline cellulose hydrolysis ability. Three individual replicates of each experiment were performed. b Colony diameters of TU-6 and Δste20 strains on MM plates containing different carbon source. Three individual replicates of each experiment were performed. *P < 0.05, **P < 0.01, ***P < 0.001. c Microscopic examination of the mycelia of TU-6 and Δste20. Strains were cultured for 48 h in submerged MM medium containing glucose. Scale bars were shown in the figure
