Abstract
Pleurotus species have been found to demonstrate a very effective bioabsorption potential for a wide range of environmental contaminants including heavy metals. The study was conducted to determine the growth tolerance and myco-accumulation potential of mycelia and fruiting body of P. djamor in mercury contaminated media.
The mycelial growth performance was evaluated on coconut water liquid media with two concentrations of mercury. meanwhile, P. djamor fruiting bodies were evaluated on rice straw-based substrate contaminated with mercury. Mycelia and fruiting bodes were aanalyzed by Inductively Coupled Plasma-Optical Emission Spectrometry.
Mycelial biomass of P. djamor was significantly inhibited in 1000 ppm of mercury. However, 1 ppm of mercury and control showed no significant difference. A decreasing pattern in volume loss was also observed having statistically significant. The fruiting bodies also showed decreased yield in contaminated substrate. Inductively Coupled Plasma Optical Emission Spectrometry analysis showed that mercury cannot be detected in both mycelia and fruiting bodies of P. djamor. Suggests that P. djamor was safe food source even grown in mercury contaminated substrates.
