Summary: Soil contamination by petroleum hydrocarbons (PHCs) is a significant problem affecting crop growth and quality. Bioelectrochemical systems (BES) are gaining attention as a promising technology for soil remediation. This review discusses the working principles, design configuration, and advancements of BES in efficiently removing PHCs from contaminated soil. It also highlights the importance of biosurfactants and biochar in enhancing PHC degradation using BES. Further research and development are needed to improve the efficiency and scalability of BES for large-scale soil remediation and power production.

Summary: Total petroleum hydrocarbon (TPH) contamination poses threats to ecological systems and human health. In this study, TPH contamination level, microbial community structure and functional genes were investigated at a multi-contaminated industrial site in Lanzhou. After the spill accident, soil bacterial communities became significantly diverse, but the dominant microbes remained the same as Pseudomonadaceae and Comamonadaceae. The abundance of hydrocarbon-degradation related genes increased significantly at the site where the spill accident occurred in multi-contaminated areas.

Summary: Nano-bioremediation is a eco-friendly technique for overcoming soil contamination caused by petroleum waste. In this study, the efficiency of oil-degrading bacterial consortium and silver nanoparticles (AgNPs) with or without fertilizer was evaluated for remediating petroleum waste contaminated soil. The results showed that the bacterial consortium alone had the highest degradation efficiency for total petroleum hydrocarbons (TPHs) after 20 days of incubation.

Summary: This study investigated the rhizoremediation potential of different wild plant species for TPH-contaminated soils. Results showed that B. seminuda, C. truncata, and H. prostrata were effective in increasing TPH removal rate by stimulating rhizosphere microorganisms. Therefore, these wild plant species could be suitable candidates for rhizoremediation of TPH-contaminated soil.

Summary: This study established six different surfactant-enhanced microbial remediation treatments on petroleum hydrocarbon-contaminated soil. The results showed that rhamnolipid-enhanced Bacillus methylotrophicus remediation achieved the highest removal rate. The assembly process of bacterial communities was found to be impacted by deterministic factors, and a significant positive correlation was observed between the deterministic assembly process and the removal rate of petroleum hydrocarbons.

Summary: The study demonstrated that cyclodextrins can enhance the desorption efficiency of petroleum hydrocarbons (PHs) in contaminated soil. The optimal desorption conditions were determined using batch desorption experiments and response surface methodology analysis. Cyclodextrins have great potential as a solubilizer for in-situ removal of PHs in petroleum-contaminated sites.

Summary: This study examined hydrocarbon degradation and microbial activity in seven sub-Arctic soils contaminated with Arctic diesel. The results showed that nutrient amendment promoted hydrocarbon biodegradation and caused significant shifts in microbial diversity and abundance. In addition, the alkane degrading gene alkB was more abundant in systems with nutrient amendment. The extent of microbial community shifts or alkB copy number increases may not be closely correlated with hydrocarbon biodegradation and bioremediation performance across different treatments or soils.

Summary: Microbial electrochemical technologies (MET) are increasingly being considered for environmental remediation applications due to their unique capabilities. However, challenges remain in applying MET for the remediation of soils contaminated by petroleum hydrocarbons. Specific strategies are needed to address the limited radius-of-influence of electrodes buried in contaminated soils, and pilot-scale testing is necessary to validate promising laboratory results.

Summary: This study evaluated the effectiveness of natural attenuation, microbial remediation, phytoremediation, and microbial-phytoremediation in degrading petroleum hydrocarbons. The findings showed that the roots of the plant absorbed small amounts of polycyclic aromatic hydrocarbons, resulting in changes in the soil microbial community structure. The abundance of petroleum-degrading bacteria and plant growth-promoting rhizobacteria increased, along with microbial diversity.

Summary: This paper proposes a hierarchical framework for petroleum hydrocarbon pollution detection and soil assessment based on an electronic nose. The framework includes four independent and collaborative functional modules: petroleum hydrocarbon pollution detection module, pollution level identification module, petroleum hydrocarbon content analysis module, and organic matter content analysis module. Experimental results show that the proposed framework can simultaneously achieve pollution detection, level recognition, petroleum hydrocarbon content analysis, and organic matter analysis. The pollution recognition rate reached 98.99%, and the pollution level recognition rate reached 97.67%. The goodness of fit for quantitative analysis of petroleum hydrocarbon content and organic matter content were 0.97 and 0.87 respectively. The hierarchical petroleum hydrocarbon pollution detection and soil assessment framework proposed in this paper can comprehensively reflect the soil information status and provide accurate decision support for land use decision and soil remediation.

Summary: This study investigated the combined remediation of crude oil-polluted soil using persulfate oxidation and hydrocarbon-degrading mixed bacteria. The results showed that the addition of 1% persulfate coupled with bioremediation resulted in 80.05% total petroleum hydrocarbon removal, higher than bioremediation or the addition of 1% persulfate alone. The combined treatment stimulated enzyme secretion and enhanced the mobility and bioavailability of the pollutants in the soil. However, excessive persulfate oxidation negatively impacted the soil environment and microbial diversity, leading to lower degradation rates. This study provides valuable insights into the integration of chemical oxidation and bioremediation for oil-contaminated soils.

Summary: The research focused on the stable carbon and hydrogen isotope effects associated with methane formation by the corrosive archaeon Methanobacterium strain IM1 during growth with hydrogen and iron. The growth resulted in methane with depleted C-13 values, while H-2 values were less impacted by growth phase. The corrosion crusts formed were composed of siderite, calcite, and iron sulfide, with attached cells found on crust surfaces and deep inside crust domes.

Summary: The phototransformation mechanisms of 1H-benzotriazole involve two alternative pathways: direct photolysis and indirect photolysis. Direct photolysis leads to N-N bond cleavage followed by nitrogen elimination with C-N bond cleavage. Indirect photolysis mainly results in aromatic hydroxylation, forming hydroxylated forms of benzotriazole.
