Abstract:

This study focused on the bioremediation role of Pleurotus eryngii in different characteristics soils contaminated with nickel (Ni) and fluoranthene. The results of bioremediation experiments showed that fluoranthene had a positive effect on the growth of P. eryngii, whereas Ni exerted a negative influence. The concentration of fluoranthene significantly decreased in inoculated soil accounting for 86.39-91.95% of initial concentration in soils and 71.46-81.76% in non-inoculated soils, which showed that the dissipation of fluoranthene was enhanced by mushroom inoculating. The highest removal rates of fluoranthene in sandy loam, loamy clay, and sandy soils reached to 87.81, 86.39, and 91.95%, respectively, which demonstrated that P. eryngii was more suitable for the bioremediation of sandy soil contaminated with fluoranthene. In addition, the presence of Ni tended to decrease the dissipation of fluoranthene in inoculated soil. Higher ligninolytic enzymes activities were detected in inoculated soils, resulting in the enhanced dissipation of fluoranthene in inoculated soils. Furthermore, P. eryngii had the ability to uptake Ni (4.88-39.53 mg kg-1 ) in co-contamination soil. In conclusion, the inoculating of P. eryngii was effective in remediating of Ni-fluoranthene co-contaminated soils.
