Summary: This study investigated the microbial reductive dechlorination method for chlorinated aliphatics in anaerobic environments, as well as the influence of different carbon sources on the dechlorinating activity. The results showed that emulsified vegetable oil (EVO) provided the highest dechlorinating activity with the DCB-1 bacterial strain. In addition, the in-situ microcosm study demonstrated that with the addition of EVO, DCB-1 and SSFL groundwater converted 90% of trichloroethylene (TCE) to ethane.

Summary: The study conducted on highly contaminated chlorinated aliphatic organics in the subsoil of Ferrara, Italy revealed the importance of microbial degradation as a key mechanism for the dechlorination process. Through analysis of microbial communities using 16S rRNA gene sequencing and metabolic gene analysis, a complex network of metabolic interactions was hypothesized to support effective reductive dechlorination. This study provides insights into the diversity of microbial communities and potential dechlorinators in contaminated aquifer systems, shedding light on the microbial processes involved in bioremediation efforts.

Summary: This review discusses the underlying mechanism of microbial electrolysis cell (MEC) in dechlorination of chlorinated organic compounds (COCs), focusing on the generation, transmission, utilization, and reception of electrons during the process. It emphasizes the crucial role of cathode materials in the electron transfer procedure. Suggestions for future research, such as model construction, cathode material modification, and expanding the applicability of MECs to removing gaseous COCs, are proposed.

Summary: This study revealed the microbial transformation potential of 6:2 chlorinated polyfluorooctane ether sulfonate (6:2 Cl-PFESA) in anaerobic microbial systems. The compound was reductively dechlorinated to 6:2 hydrogen-substituted polyfluorooctane ether sulfonate (6:2 H-PFESA) as the sole metabolite. The results suggest that the mechanism for reductive dechlorination of 6:2 Cl-PFESA is likely co-metabolism rather than organohalide respiration. Additionally, the product 6:2 H-PFESA showed lower sorption affinity, indicating increased mobility in the environment.

Summary: A bioelectrochemical process combining two membrane-less reactors equipped with graphite granules counter electrode was developed for perchloroethylene removal. The reductive reactor completely reduced PCE into VC and Eth, which were efficiently removed by the oxidative reactor. Different redox niches in each compartment allowed the co-existence of both reducing and oxidative reactions, enhancing the overall efficiency of PCE removal.

Summary: This study summarizes the outcomes of the long-term in-situ application of glycerol for the enhanced reductive dechlorination of chlorinated ethenes (CEs). Glycerol injection resulted in an increase in the abundance of fermentative Firmicutes, leading to the change of groundwater conditions suitable for the growth of organohalide-respiring bacteria (OHRB). The concentrations of pollutants decreased and the final degradation products were ethene and ethane.

Summary: The presence of chlorinated solvents polluting groundwater in urbanized areas is a significant environmental issue. This paper presents a comprehensive approach to remediate the contamination, using two distinct remediation technologies. The development of an integrated conceptual site model helps understand the hydrogeochemical characteristics of the site and support decision-making. Hydrochemical monitoring during the remediation process allows for the evaluation of strategy performance and investigation of possible rebound effects.

Summary: This study shows that the joint use of H-2 and O-2 can significantly promote the microbial transformation of chlorinated hydrocarbons. Illumina sequencing analyses revealed the formation of a specific microbial community in the H-2/O-2 microcosm, with certain microbes utilizing H-2 and O-2 as energy sources for chlorinated hydrocarbon conversion.

Summary: Inorganic arsenic and organochlorines often coexist in anoxic groundwater environments, posing challenges for bioremediation. This study investigated the dechlorination performance of a microbial consortium under different concentrations of arsenate or arsenite and found that the impact of arsenic on dechlorination differed between the two scenarios. The study also revealed that the vinyl chloride-to-ethene step was more susceptible to arsenic exposure and fermentative bacteria showed high potential for arsenic resistance. The findings provide insights for modifying bioremediation strategies at co-contaminated sites.

Summary: Phytoremediation is a cost-effective and environmentally sustainable technology for remediating contaminants, but shows limited efficacy for persistent organic pollutant (POP)-contaminated soils. This study demonstrates that the synergistic combination of reactive nanoparticulate zero-valent iron (nZVI) and alfalfa significantly enhances the remediation efficiency of polychlorinated biphenyl (PCB)-contaminated soil, with nZVI influencing plant root metabolomics and rhizosphere microbial community to facilitate PCB degradation.

Summary: In this study, a sequential reductive/oxidative bioelectrochemical process was used to remove chlorinated aliphatic hydrocarbons (CAHs) from contaminated groundwater. The sequential system consisted of two membrane-less microbial electrolysis cells (MECs) connected in series. The results showed that the sequential process effectively mineralized CAHs and reduced their ecotoxicity, as evaluated by biomarkers and ecotoxicity tests.

Summary: In underwater-unsaturated conditions, microbial activity is controlled by various environmental factors, requiring a detailed understanding of the physical and chemical conditions in the microscale pore space and how microorganisms respond to energy and matter fluxes. Microscale modeling allows for resolution of processes to their fundamental level, but integration of components for simulation of microbial activities at the microscale remains limited.

Summary: This study investigated the use of superabsorbent polymer (SAP) as a supplement to constructed wetlands (CWs) for enhanced removal of hydrophilic pesticides. The results showed that SAP improved the retention of neutral pesticides in the gel-water phase of w-SAP, while also enhancing the removal of pesticides in lab-scale CWs contaminated by runoff water. Overall, the addition of SAP in CWs led to a significant increase in the removal efficiency of various pesticides, especially hydrophilic ones.

Summary: The organic matter of living plants is the precursor material of the organic matter stored in terrestrial soil ecosystems. Recent research has shown that microbial necromass plays a crucial role in the formation of soil organic matter, but there is still a lack of complete understanding regarding the growth, carbon utilization, and decay cycles of microorganisms in soil.

Summary: Microbial biomass residues play an important role in biogeochemical cycling, but the mechanism by which they are sequestered in soil organic matter remains elusive. This study revealed that bacterial biomass is predominantly utilized by fungi and stabilized as fungal necromass, contributing to soil organic carbon sequestration. The study also identified three phases in the metabolism of microbial biomass residues, with the final phase focused on C preservation rather than energy production.

Summary: Global development heavily relies on the overexploitation of natural resources, leading to increased greenhouse gas concentrations and global climate change. Achieving carbon neutrality by 2050 is crucial, requiring reform of production systems to reduce emissions and promote carbon capture. Innovative technologies in renewable energy, food systems, waste valorization, and carbon-negative manufacturing offer solutions to mitigate climate change and support sustainable development.
