“…In one study, full-scale composting bioremediation was applied to the petroleum-contaminated soil at an oil-polluted operational area using a mixture of sugarcane/bagasse as composting materials. After 2 months, up to 99% of crude oil was degraded [51]. Even though the preparation of the contaminated soil piles may be required prior to the composting, the application of this approach for crude oil degradation is considered relatively uncomplicated and environmentally friendly.…”

In this study, we aim to investigate the efficiency of crude oil bioremediation through composting and culture-assisted composting. First, forty-eight bacteria were isolated from a crude oil-contaminated soil, and the isolate with the highest crude oil degradation activity, identified as Pseudomonas aeruginosa, was selected. The bioremediation was then investigated and compared between crude oil-contaminated soil (S), the contaminated soil composted with fruit-based waste (SW), and the contaminated soil composted with the same waste with the addition of the selected bacterium (SWB). Both compost-based methods showed high efficiencies of crude oil bioremediation (78.1% and 83.84% for SW and SWB, respectively). However, only a slight difference between the treatments without and with the addition of P. aeruginosa was observed. To make a clear understanding of this point, bacterial communities throughout the 4-week bioremediation period were analyzed. It was found that the community dynamics between both composted treatments were similar, which corresponds with their similar bioremediation efficiencies. Interestingly, Pseudomonas disappeared from the system after one week, which suggests that this genus was not the key degrader or only involved in the early stage of the process. Altogether, our results elaborate that fruit-based composting is an effective approach for crude oil bioremediation.

Microorganisms also play an important role in soil ecosystems. Microorganisms can adsorb heavy metals in soil. Therefore, microbial remediation technology is widely used in the remediation of heavy metal-contaminated soils. It is of great significance to carry out research on soil microbial ecological effects in polluted areas to solve the problem of remediation and improvement of contaminated soil. This paper collects soil samples contaminated by heavy metals in a certain area, and measures the panel data such as pH value, electrical conductivity, and heavy metal content of the soil samples, and then uses microbial remediation technology to remediate the contaminated soil, and estimates the analysis results through the combined removal of heavy metals and soil remediation. It was found that the organophosphate-solubilizing bacteria OPW2-6 could increase the soil pH, thus improving the soil properties and achieving a good remediation effect.

“…However, with the rapid development of oil drilling, the petrochemical industry, and the wide use of petroleum products, the soil pollution of petroleum has become a serious environmental problem (Liu et al, 2020a). Petroleum hydrocarbons could affect DNA, disrupt normal functions of cellular membranes threatening the life cycle of organisms (Parnian et al, 2022). Long-term petroleum pollution not only degrades the soil function but also endangers the health of human and ecosystem.…”

With the development of industrialization, soils around the world have been polluted by heavy metals and oil to different degrees in recent years, and soil remediation has become a global problem. Phytoremediation has a wide application prospect because of its environmental friendliness and easy availability of materials.ObjectiveTo explore the effects of soil types and root exudates on the removal of cadmium and petroleum hydrocarbon in soils.MethodA pot experiments with three soil types (sandy, loamy and clayey) of the Changning-Weiyuan area of Sichuan province and three root exudates (citric acid, glycine, and maltose) were carried out using Sorghum sudanense (Piper) Stapf., Lolium perenne L., and Festuca arundinacea L. as test materials. Plants were grown in soils contaminated by cadmium and petroleum at different concentrations.ResultThe biomass of S. sudanense, the translocation ratio and removal rate of cadmium in S. sudanense decreased gradually with increasing soil cadmium concentration. The promotion effects of the three root exudates on S. sudanense were in the following order: citric acid > glycine > maltose. At the same cadmium pollution conditions, the biomass levels of S. sudanense in sandy, loamy, and clayey soils were in the following order: clayey soil > loamy soil > sandy soil. On the contrary, the concentration, translocation ratio, and removal rate of cadmium in S. sudanense grown in the different soils treated with root exudates were in the following order: sandy soil > loamy soil > clayey soil. Under the three soil conditions, the fresh weight of F. arundinacea (0.36 ~ 0.68 g) and S. sudanense (0.51 ~ 0.99 g) increased significantly (p < 0.05). The total petroleum hydrocarbons degradation efficiencies of F. arundinacea, L. perenne, and S. sudanense were high in sandy soil (34.27% ~ 60.52%). Changing the type of root exudate had a significant impact on the degradation of total petroleum hydrocarbons in sandy soil (p < 0.05).ConclusionThis study showed that soil types impacted the accumulation of cadmium and petroleum in plants. Phytoremediation of cadmium and petroleum contaminated soil could be enhanced by the application of root exudates. This study recommend that the method is suitable for field remediation of soils contaminated with mild cadmium and petroleum hydrocarbons.
