| description | Pollution is the addition of something that does not naturally exist to the ecosystem. Heavy metals pollution has become a global concern as it imposes a lot of negative impacts on living organisms, human, animals and plants. Mycoremediation is the process of using fungi in order to remove contamination from the environment. The objective of this study was to determine the effect of zinc (Zn) and silver (Ag) on the growth of Pleurotus ostreatus. In this study, the mycelia of P. ostreatus was cultured on PDA medium containing different concentrations of Zn or Ag ranging between 1 mg/L to 200 mg/L. The optimum growth obtained by P. ostreatus in Zn plates was 4.2 cm at 5 mg/L and for Ag was 4.2 cm at 1 mg/L and 5 mg/L. It was noticed that Ag exerted higher toxicity towards P. ostreatus compared to Zn as the growth for Ag plates was slower than Zn plates. P. ostreatus was able to serve as a potential model for mycoremediation as P. ostreatus had the ability to grow and tolerate high concentrations of heavy metals namely Zn and Ag. |
