The exploitation of petroleum, the production and use of petroleum products causes pollution that is harmful to the ecology and environment. At present, petroleum hydrocarbon pollution has become a universal concern in the world. As one of the bioremediation methods, plant root exudate repair has the effect of eliminating toxic substances in the environment. To explore the role of root exudates glycine in phytoremediation of petroleum-contaminated soil, seed germination and pot experiments were carried out to study the effects of glycine on the degradation of petroleum hydrocarbons in different plants and soil types. The results showed that when the concentration of petroleum pollutants was constant, the order of seed germination rate of the eight plants was ryegrass > sudan grass > white clover > tall fescue > alfalfa > pennisetum > canine root > maize grass.1000 mg L−1 of glycine could effectively promote plant biomass and the petroleum hydrocarbons degradation rate. The degradation effect was ryegrass + glycine > ryegrass > sudan grass + glycine > sudan grass > white clover + glycine > white clover. The degradation rate of ryegrass + glycine in 18,000 mg kg−1 petroleum-contaminated soil reached 55.7%. All plants had the highest biomass and plant height in loamy soil, while the highest degradation rate of petroleum hydrocarbons was observed in sandy soil, ranging from 50.36% to 59.36%. Among them, ryegrass combined with 1000 mg L−1 of glycine reached the highest petroleum hydrocarbons degradation rate of 59.36% in sandy soil. Ryegrass, sudan grass and white clover had the potential to remediate petroleum-contaminated soils. In the three types of soil, ryegrass had a strong remediation efficiency, and the degradation effect to petroleum hydrocarbons was more significant after the addition of glycine. Therefore, ryegrass can be planted with glycine as a priority for remediation in oil field areas contaminated by petroleum hydrocarbons.

“…To diminish the hazards of exposure, renovate soil functions, and offer ecosystem services, it is imperious to implement risk-based remediation policies for polluted soils by petroleum hydrocarbons, particularly for agricultural exploitation (Zhang et al, 2021). On-site and off-site treatments involve the separation and demolition of contaminants from the soils polluted by petroleum hydrocarbons through chemical, physicochemical, biological, heat and thermal, electric, ultrasonic, acoustic, and electromagnetic methods are applied to remediate soil polluted petroleum hydrocarbon (Ruley et al, 2022;Ambaye et al, 2022;Chen et al, 2023). Regarding biological approaches, native or non-native microorganisms are inoculated to soils to diminish or remove hydrocarbon compounds form polluted ecosystems through bioremediation processes (Narayanan et al, 2023).…”

Bioremediation of petroleum-polluted soils is deemed nowadays extremely to remedy the soils polluted by petroleum hydrocarbons. In the study synergic impacts of two amendments included biochar and iron nanoparticles were assessed to monitor the natural polluted soil by gasoil. Contaminated soil samples were collected in a polluted site in southern Iran by gasoil about 3 mg kg− 1 of soil. Soil samples were treated with 0, 1, 5 and 10% by weight of biochar and 0, 2 and 10 g kg− 1 synthetized iron nanoparticles under the incubation at 28 ± 2°C and 70% field capacity moisture for 35 days. The samples were analyzed to measure total petroleum hydrocarbon (TPH) and microbial respiration rate. According to the results, the first order kinetic model fitted well with an R2 value of 0.934–0.98 for the soils treated with different levels of biochar and nanoparticles. A significant and positive correlation (r = 0.774, P < 0.01) derived from a polynomial equation was observed between cumulative respiration rate and change percentage of gasoil during biodegradation (ΔTPH). Increasing of biodegradation because of higher biochar is mainly related to improvement of circumstance for higher microbial activity, while inhibition effects of iron nanoparticles on decreasing microbial activities in 10 g kg− 1 is related to toxicity of nanoparticles on microbes. After 35 days of incubation, the highest ΔTPH was observed for 10% biochar and 2 g kg− 1 iron nanoparticles, as well this treatment showed that the greatest constant of degradation (K = 0.0628) and lowest half-life (t1/2=11.3 days). In overall, the results showed that combined remediation strategies profoundly improve the bioremediation rate by indigenous microorganisms and further studies needs to evaluate different level of iron nanoparticles or even in combined with other remediation technologies.

“…The zone of soil affected by a plant's root activity with the highest concentration of carbon and altered microbial diversity is called the rhizosphere and has lower pH, oxygen, and carbon dioxide than bulk soil (Brady and Buckman, 1990;Slaughter, 2021). To ensure successful decontamination of crude oil contaminated soil with plants, the microbial population around the root zone specifically the petroleum hydrocarbon degrading species must be stimulated to grow or their population increased by augmenting soils with the species (Ruley, et al, 2022). It is important that the identity of rhizosphere fungi around potential plants to be used for rhizoremediation should be investigated and their physiology and responses to contaminants known (Zuzolo, et al, 2021).…”

Co-metabolism between plants and rhizosphere microbes is the mainstay of rhizoremediation of contaminated soils. The aim of the current study was to isolate and screen selected rhizosphere micro-fungi of two Asteraceae (Tridax procumbens and Chromolaena odorata) collected from the wild in University of Lagos, Akoka, Lagos State for bioremediation potential. Rhizosphere fungi were isolated, identified and evaluated for crude oil myco-remediation. The inhibitory effect of different concentrations of crude oil on mycelial growth of the most abundant fungi was determined with poisoned plate assay method. The most abundant and recurring fungi around C. odorata and T. procumbens were determined using the serial dilution and plating methods. Analysis of the rhizosphere soil of T. procumbens and C. odorata showed they were sandy loam type. C. odorata soil had higher moisture, organic carbon, and acid content than T. procumbens. Aspergillus flavus and Trichoderma harzianum were the most abundant and recurring fungi in C. odorata and T. procumbens, respectively. Thirty-nine micro-fungi belonging to twenty genera were isolated from the test plants’ rhizosphere. A. flavus and T. harzianum tolerated 2.50 to 10.00% crude oil contamination assessed with their mycelial growth inhibition reducing with time. A. flavus and T. harzianum caused a 68.45% and 86.71% reduction of crude oil contamination respectively, in a time dependent manner. The filamentous fungi ~A. flavus and T. harzianum can potentially be used to simultaneously ameliorate crude oil contaminated soils in conjunction with C. odorata and T. procumbens, respectively in the innovative technology termed rhizoremediation.
