Different concentrations of Zn2+ influence the hyphal growth of the Trichoderma reesei RUT-C30 strain. a RUT-C30 grown on MM plates supplemented with Zn2+ at final concentrations of 0–5 mM. b Colony diameter of T. reesei RUT-C30 cultured on MM plates under different concentrations of Zn2+. The final values are presented as the means ± standard deviation (SD) of three independent experimental results. Asterisks indicate significant differences compared with the control (*P < 0.05, according to Student’s t-test). MM, minimal medium
