“…Due to worldwide demand, population growth, and extensive use of petroleum products, the petrochemical industry has continued to grow and continues to pollute both aquatic and terrestrial environments. This can happen during production, transport, usage, or disposal of the oil (Ramadass et al, 2018;Baoune et al, 2019). Contamination of soil by petroleum hydrocarbons is especially problematic for a variety of physical and chemical reasons and is detrimental to ecosystems due to their lipophilic, mutagenic, and carcinogenic effects of its constituents.…”

“…This impacts the physical properties of soil such as permeability and moisture content, in addition to chemical properties such as pH and the availability of nutrients such as nitrates, phosphates, and sodium. These physical and chemical changes result in reduced growth of microorganisms and plant life within the soil (Baoune et al, 2019;Devatha et al, 2019). The physical and chemical changes caused by pollution of a pristine ecosystem occur rapidly, greatly impacting the functionality of ecosystem services in that environment.…”

The soil microbiome consists of a vast variety of microorganisms which contribute to essential ecosystem services including nutrient recycling, protecting soil structure, and pathogen suppression. Recalcitrant organic compounds present in soils contaminated with fuel oil can lead to a decrease in functional redundancy within soil microbiomes. Ecopiling is a passive bioremediation technique involving biostimulation of indigenous hydrocarbon degraders, bioaugmentation through inoculation with known petroleum-degrading consortia, and phytoremediation. The current study investigates the assemblage of soil microbial communities and pollutant-degrading potential in soil undergoing the Ecopiling process, through the amplicon marker gene and metagenomics analysis of the contaminated soil. The analysis of key community members including bacteria, fungi, and nematodes revealed a surprisingly diverse microbial community composition within the contaminated soil. The soil bacterial community was found to be dominated by Alphaproteobacteria (60–70%) with the most abundant genera such as Lysobacter, Dietzia, Pseudomonas, and Extensimonas. The fungal community consisted mainly of Ascomycota (50–70% relative abundance). Soil sequencing data allowed the identification of key enzymes involved in the biodegradation of hydrocarbons, providing a novel window into the function of individual bacterial groups in the Ecopile. Although the genus Lysobacter was identified as the most abundant bacterial genus (11–46%) in all of the contaminated soil samples, the metagenomic data were unable to confirm a role for this group in petrochemical degradation. Conversely, genera with relatively low abundance such as Dietzia (0.4–9.0%), Pusillimonas (0.7–2.3%), and Bradyrhizobium (0.8–1.8%) did possess genes involved in aliphatic or aromatic compound degradation.

“…The application of plant-associated bacterial inoculants is gaining increasing interest in sites of mixed contamination, caused by the presence of organic and inorganic compounds. Polycyclic aromatic hydrocarbons (PAHs) are some of the most widespread organic pollutants; their fate in soils is of great environmental concern due to their potential toxicity, mutagenicity and carcinogenicity (Baoune et al, 2019). Mixed contaminated soils represent a source of potentially beneficial bacteria associated with plants that could be used as part of microbial-assisted remediation strategies targeting this type of site (Weyens et al, 2009).…”

“…However, in the industrialized areas, there is a synchronous effect of heavy metals and petroleum contamination, and these two types of pollution impede the remediation process of the contaminated soils (7). Various technologies have been applied to remediate petroleum hydrocarbon-contaminated soil, such as bioremediation, volatilization, surfactant flushing, and chemical oxidation (8,9). However, these techniques are generally expensive and can lead to incomplete decomposition of contaminants (10).…”

“…However, these techniques are generally expensive and can lead to incomplete decomposition of contaminants (10). The efficiency of each method highly depends on the pollution type and soil chemical properties of each area (9). Among above-mentioned remediation methods, biodegradation (phytodegradation) is an environmentally friendly technique applicable for the remediation of soils contaminated by hydrocarbons (11).…”

Background: Soil remediation is one the important problem in environmental studies. Thus, this research was conducted to evaluate the effect of organic chelates and gibberellic acid (GA 3 ) on the degradation of crude oil in the soil co-contaminated with Ni and crude oil under canola cultivation. Methods: For treatments, HEDTA and NTA chelates at rates of 0 and 2.5 mmol/kg soil and foliar GA 3 (0 (GA 3 (-) and 0.05 (GA 3 (+) mM) were used. In addition, the soil was polluted with Ni (0 and 100 mg Ni/kg soil) and crude oil at rates of 0, 2, and 4% (W/W). The plant used in this experiment was canola. The concentration of Ni in soil and plant was measured using atomic absorption spectroscopy (AAS). The concentration of total petroleum hydrocarbon (TPH) was measured using GC-mass. The mean differences were calculated according to the least significant difference (LSD) test. Results: The greatest degradation of crude oil belonged to the non-Ni-polluted soil under cultivation of GA 3 -treated plant, while the lowest one was observed in the soil received the greatest level of HEDTA and NTA chelates. Applying 0.05 mM GA 3 foliar significantly increased the degradation of crude oil in soil and Ni in plant shoot by 12.1 and 8.3%, respectively. In addition, soil microbial respiration was also increased by 11.3%. Conclusion: HEDTA, NTA, and GA 3 had a significant effect on the Ni phytoremediation efficiency and degradation of crude oil in soil that is a positive point in environmental pollution. However, the role of soil physico-chemical properties on the phytoremediation efficiency cannot be ignored. Citation: Baghaie AH, Daliri A.
