Abstract

The bacteria Pseudomonas.aeruginosa and Staphylococcus.lentus and yellow corn plant Zea Mays were used in the treatment of soil contaminated with crude oil and some heavy elements. The results of the physical and chemical analysis showed that the soil of the study was mixed, and that the two types of bacteria achieved significant results in removing heavy elements and crude oil from the soil. After 60 days of treatment, the interaction treatment B3N1 achieved the best removal of copper, chromium, nickel,and iron from the soil (4.367, 7.000, 10.133, 270.33, 2.160) ppm, respectively, at a concentration of oil contamination of 6%, compared to the control treatment B0N0, which achieved (8.033). , 15.600, 19.500, 541.67) ppm, respectively, for copper, chromium, nickel, iron, and hydrocarbons, and the interaction treatment between the two types of bacteria and the yellow corn plant achieved the best removal percentage of crude oil and heavy elements for the various concentrations used in the experiment, and the bacteria had a significant effect on plant height and area leaf compared to the control treatment.
