The effect of utilizing organic waste and Rhodococcus bacterium in reducing the total petroleum hydrocarbons of a contaminated saline soil

There are hardships in oil-polluted soil remediation that are increased by factors, such as soil salinity and pollution age. This study aimed to evaluate the effect of the native strain of Rhodococcus bacterium and organic waste on the the total petroleum hydrocarbons reduction in contaminated saline soil by crude oil in incubation condition. For this purpose, a full factorial experiment using a completely randomized design was conducted with four factors: bacterial inoculation of Rhodococcus cercidiphylli Y1M65003, 5% spent mushroom compost, 5% sugarcane bagasse, and addition nitrogen and phosphorus with 100: 10: 1 ratio from urea and superphosphate triple. The analysis of variance of total petroleum hydrocarbons elimination showed that all four factors could significantly affect (p
