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: 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 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: Soil plays a vital role in supporting life on Earth, and its protection from contamination is of great importance. This study focuses on optimizing the ex situ soil washing process using surfactants, aiming to reduce the costs of raw materials, energy, and water resources. Two surfactants, SDS and Tween 80, were tested for decontaminating oil-contaminated soil, and the washing conditions were optimized using a design of experiments software. The results showed that Tween 80 achieved a TPH removal efficiency of (80.7 +/- 3.2)% after 5 hours of washing, while SDS achieved (90.7 +/- 2.8)% after 2 hours at 200 rpm. The potential for reusing the washing solutions was evaluated, and the safe disposal of the washing solution was ensured by using activated carbon to remove the surfactants.

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: 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: This study demonstrates the use of Microbial Induced Calcite Precipitation (MICP) to create consolidated bricks from Martian Simulant Soil (MSS) and Lunar Simulant Soil (LSS). By introducing an organic polymer, guar gum, and a bio-catalyst, NiCl2, the compressive strength of these biologically grown bricks was increased. The slurry of simulant soil and microbe consolidated into desired shapes through a casting method. Field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), and thermogravimetry (TG) confirmed the MICP-mediated consolidation of the simulant soil.

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: 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.
