Abstract

Background/Aim: The heavy metals, cadmium (Cd) and lead (Pb), are often implicated as environmental pollutants. Therefore, the biosorption potential of Pleurotus tuber-regium in lead and cadmium polluted soil was investigated by this work. Methods: Four kilograms of each humus soil sample was weighed into eight different black nursery cellophane bags and polluted with 0.5 g, 1.0 g and 2.0 g of lead and cadmium in triplicate. Pleurotus sclerotia were then planted in these polluted soil samples, and distilled water was added ad libitum. Results: The results showed that the growth performance was dose-related in lead-polluted soil. The Pleurotus tuber regium mushroom in the lead-polluted soil samples indicated a dose-dependent absorbed lead concentration in the results. Cadmium-polluted soil samples did not support the growth of the Pleurotus tuber regium mushroom at the various concentrations of cadmium used after day 30. Therefore, the findings suggest that the Pleurotus tuber regium mushroom and its sclerotia have intrinsic properties for the absorption of lead and cadmium. Conclusion: The findings suggest that the Pleurotus tuber regium mushroom and its sclerotia have intrinsic properties for the absorption of lead and cadmium.

Highlights

Heavy metals are biomagnified in the food chain because they are nonbiodegradable (Singh et al, 2008; Gupta and Singh, 2019)
Because these metals produce significant contamination of the environment and obstruct various cellular functions, they constitute a risk to human health when they are carried down the food chain
As the lead concentrations increased it reduced the size of these measured parameters

Summary

Introduction

Heavy metals are biomagnified in the food chain because they are nonbiodegradable (Singh et al, 2008; Gupta and Singh, 2019). Because these metals produce significant contamination of the environment and obstruct various cellular functions, they constitute a risk to human health when they are carried down the food chain They can induce harmful effects in organisms even in trace amounts. Mushroom species' ability to breakdown waste via secretion of a variety of hydrolyzing and oxidizing enzymes allows them to produce dietary protein in the form of biomass or fruiting bodies from various wastes (Kuforiji and Fasidi, 2008). This has piqued the interest of scientists working on mushroom cultivation and waste remediation. Having considered the relevance of Pleurotus tuber-regium, the researcher embarks on this study to determine the biosorption potentials of the fungus Pleurotus tuber-regium using heavy metals such as cadmium and lead
