The growth situation of T. mentagrophytes wild-type strain and ZafA gene mutant strain on SDA-Zn medium with 800, 1000, 1200, 1400 and 1600 μM zinc sulfate. a The growth situation of ZafA gene mutant strain, the growth of T. mentagrophyte is inhibited, especially in Zn800 and Zn1000. b Under the microscope, there is good quantity of mycelium in ZafA gene mutant strain, but the number of conidia is reduced. c The wild-type strain grows normally, and with increasing of zinc ion concentration, the growth rate is accelerated. d Under the microscope, there are good quantity of mycelium and a mass of conidia in wild-type strain
