Mycoremidation of petroleum hydrocarbons of the refinery wastewater in Najaf Iraq (2-mixiture of fungi)‎

الملخص EN

The present study deals with investigate the possibility of some fungus in the removal of petroleum hydrocarbon and some pollutant from Najaf oil refinery wastewater.The study have two axes the first is isolate and diagnose fungus of oil waste water and the soils surrounding as it was isolated (5) species belonging to (3) genes, three isolate were selected which have thee frequency Penicillium sp.

49.51% ,A.

niger 10.67% and A.

terreus 34.95% in the experiment a mixture offungus used to remove oil hydrocarbon in the media center as the sole source of carbon and energy .The result showed that ,the mixture of A.niger and A.terreus remove(66.63%) of the weight of hydrocarbons existing in media and showed efficiency in reducing a conductivity, salinity and TDS and total hardness and hardness calcium, hardness magnesium, alkalinity and nitrite, nitrate, phosphate and sulfate by (70.51)% and (71.06)% and (59.43)% and (67.23)% and (63.77)% and (80.5 )% and (76.87)% and (62.5)% and (67.2)% and (63.6)% (71.4)%, respectively , while the triple mixture were the lost in the removal of oil hydrocarbons and other parameters.
