During 2015–16, the presence of micromycetes species in aquatic ecosystems was studied in Iran. Samples were collected from rivers, lakes and wetlands. For isolation, agar disks were transferred to plates containing water samples. The plates were incubated at 25–27° C for 21 days in 12 h light/12 h dark condition. Then from the mycelium grown on the agar disks, pure cultures were obtained. Fin...
