Abstract

Terrestrial ecosystems’ bearing center is the soil. Soil’s chemical and physical properties change to varying degrees as a result of oil pollution. Soils that have been polluted have a unique composition of microbial species, making them an excellent source of materials for the bioremediation of oil-contaminated soil through biological enhancement. A more effective biological method for soil remediation can be developed by comprehending the microbial composition of petroleum-contaminated soil. The physical and chemical properties of the bacterial and fungal microbiota in petroleumcontaminated soil (total organic carbon, alkaline hydrolysable nitrogen, total phosphorus, total potassium, available potassium, Cu, Zn, and Cd) were measured using 16 S rRNA and ITS genetic markers. Petroleum pollution was found to have a significant impact on the relative abundance of Proteobacteria, Pseudomonas, Pseudoxanthomonas, and Pseudoallescheria in oil-contaminated soil.
