What is Mycoremediation? It is a form of bioremediation, the process of using fungi to degrade or sequester contaminants in the environment. Stimulating microbial and enzyme activity, mycelium reduces toxins in-situ. Some fungi are hyperaccumulators, capable of absorbing and concentrating heavy metals in the mushroom fruit bodies.

Mushroom at a closer look
-
Oyster mushroom(Pleurotus ostreatus)
Grows on woods Contains important minerals( K, Cu, et.) and Vit ( B2, B12, Ascorbic, cinamic acid, vanillin, courmarone acid 0.9-2% sugar content/ fresh stuff ( 45 cal/100g) Cell-wall contains Chitin which has a heavy metal absorbing properties
-
Purpose of the study
to investigate the transfer
of transuranium elements, specifically Plutonium and
Americium from the ground to the oyster mushrooms.

Conclusion:
It was expressly proved the competence of oyster mushroom to extract radionuclides from the contaminated soil.
