Environmental implications of three Pleurotus isolate growth for water remediation in the perspective of climate change in New Egyptian Delta

Abstract Recently the integrated different interdisciplinary studies derived the environmental solutions of the climate change impacts (e.g., cultivation, wastewater treatment, managing groundwater resources). Thus, this paper focused on the application of bioremediation to maximize the use of wastewater for new reclamation areas in the Northwest Egyptian desert (New Egyptian Delta (NED). In NED project, the drainage water samples collected from Nile Delta drains will provide the main unconventional water resources for irrigation through the new Hammam canal. Therefore, three Pleurotus isolates were grown moderately on two natural media, the first containing Salvia extract (MDA) and the second containing Thymus (TDA) extract replacing potato infusions in standard PDA. Pleurotus ostreatus (P.O) isolate records the highest growth among the 3 tested fungi on modified media. PO records 4.49 and 4.41 cm on (MDA) and (TDA); respectively. There is a marked decrease in the majority of heavy metals concentrations on sterile drainage water amended with liquid PDA broth and inoculated with three tested Pleurotus isolates individually. At the end of the incubation period, Pleurotus ostereatus are more efficient in the removal of Al, Co, Cr, Ni by 53.15, 95.87, 58.47, 85.07%; respectively. Pleurorotus pulmonarius (P.P) is more potent in the removal of Cd, Si, Sn, Sr, and V by 70.37, 56.59, 41.19, 52.78, 96.24%; respectively. Pleurotus floridanus (P.F) is actively over the former species in the removal of Ba, Fe, Mo by 87.84, 46.67, 97.34%; respectively. Cu, Mn, Pb, As, Se couldn’t be detected as the control sample recorded measurements below 0.009 mg L -1 . Unexpected increase in Zn among the different treatments was detected from 05.04% to 07.01%.
