Abstract Background Soil pollution by petroleum hydrocarbons (PHCs) reduces yield changing the physico-chemical properties of soil and plants due to PHCs’ biotoxicity persistence. Thus, removing PHCs from is crucial for ecological sustainability. Microbes-assisted phytoremediation an economical eco-friendly solution. The current work aimed develop use bacterial consortia (BC) degradation plant growth enhancement in hydrocarbon-contaminated soil. Initially, enriched microbial cultures (that were prepared PHCs-contaminated soils five distinct regions) obtained via screening through microcosm experiments. Afterward, two best tested under various temperature pH ranges. After culture optimization, isolation characterization strains done construct BC. These constructed BC a pot experiment chickpea contaminated Results Findings revealed that exerted significant phytotoxic effects on physiology when cultivated soil, reducing agronomic physiological traits 13–29% 12–43%, respectively. However, presence BC, impacts reduced, resulting up 24 − 35% improvement characteristics as compared un-inoculated controls. Furthermore, boosted chickpea’s nutritional absorption antioxidant mechanism. Most importantly, phytoremediated 52% initial concentration; however, adding BC1 BC2 with further increased this removal remediated 74% 80% concentration, Conclusion In general, outperformed (with few exceptions) promoting elimination.
