| Abstract | ||
| The results of the present study showed the ability of Basidiomyces mushrooms Pleurotus ostreatus, Agrocybe aegrita and Phellinus sp. for growth in Baji refineries wastewater, the dry weights of these mushrooms varied with wastewater sources, P.ostreatus growth superior on other mushrooms in North,Salh-Aldin and Oil refineries in which dry weights were 0.476, 0.426 and 0.607 g/100 ml, while the highest dry weights recorded by A. aegrita and Phellinus sp. were 0.376 and 0.388 g/100ml in treatment water. The absorption of iron by A. aegrita superior on other mushrooms in North refinery resulting in 0.96 mg/g dry weight, followed by P.ostreatus which recorded 0.8 and 0,79 mg/g dry weight in Oil and Salh-Aldin refineries. A. aegrita also superior on other mushrooms in absorption of Copper in North refinery resulting in 0.63 mg/g dry weight, followed by P.ostreatus which recorded 0.43 and 0.41 mg/g dry weight in North and Salh-Aldin refineries.The highest Zinc absorption was by Phellinus sp. in Oil and Salh-Aldin refineries resulting in 0.9 and 0.8 mg/g dry weight followed by P.ostreatus which recorded 0.7 , 0.66 and 0.63 mg/g dry weight in Oil, North and Salh-Aldin refineries, respectively. P.ostreatus superior on Cobalt and Nickel absorption in all wastewater refineries compared to A. aegrita and Phellinus sp., the highest absorption of P.ostreatus was 0.71 and 0.87 mg/g dry weight in North refinery, respectively. | ||
