Summary: This study focuses on investigating the efficiency of pharmaceutical degradation using a double-chamber microbial fuel cell. A selective liquid chromatography-tandem mass-spectrometric method was developed and validated for quantification of compounds used in the experiments, with a maximum removal rate of 96%. While the presence of pharmaceuticals initially had a negative impact on power generation, increased power output was achieved after reactor acclimatization, maximizing organics removal at 30 hours of retention time.

Summary: Bioaugmentation using an eco-friendly bioformulation containing Janibacter cremeus showed efficient degradation of HMX in soil under both aerobic and anoxic conditions, with better results observed under saturated moisture conditions. The study also identified potential intermediates and demonstrated the effectiveness of using an inexpensive and natural carrier for immobilizing explosive-degrading microbes in site remediation.

Summary: In recent decades, hydrocarbon concentrations in soil and water have increased due to accidents or operations involving crude oil and petroleum input into the environment. Bioremediation has emerged as an effective environmental recovery approach, utilizing hydrocarbon compounds as growth substrates for microorganisms, contributing to the stabilization of impacted areas.

Summary: In this study, the biodegradation ability of a native bacterial species WS2-R2A-65 isolated from nitramine explosive-contaminated effluent was investigated. The results showed that WS2-R2A-65 was able to cometabolically degrade HMX and RDX with high efficiency, resulting in the formation of simpler and less hazardous end products.

Summary: Datura species are known for their high concentration of tropane alkaloids, which can lead to poisoning when accidentally mixed with edible crops. Testing on frozen spinach and spinach-based infant food products found that some samples had levels close to the maximum limits set by the European Union. This highlights the global concern over the presence of these compounds in various commodities.

Summary: Bacillus albus YUN5, isolated from doenjang, showed high degradation capabilities for aflatoxin B1 (AFB1) and aflatoxin G1 (AFG1). The cell-free supernatant (CFS) of B. albus YUN5 exhibited the highest degradation efficiency, while negligible degradation was observed in other fractions. Optimal degradation conditions were determined to be 55℃, pH 7-10, and salt concentration of 0-20%. Liquid chromatography-mass spectroscopy analysis revealed the target sites of degradation. The application of B. albus YUN5 in doenjang fermentation showed better reduction of AFB1 and AFG1 compared to without B. albus YUN5.

Summary: PCBs, common pollutants in electronic waste, can be effectively removed from the environment through bioremediation. Research has shown that certain bacterial strains are the most proficient PCB degraders under aerobic conditions, while enzymes in soil also have the capability to break down PCBs.

Summary: This article provides a comprehensive review of aerobic composting technology for remediating soil contaminated with total petroleum hydrocarbons (TPHs). The studies show that composting can successfully treat TPH contamination in various types of soils, with removal efficiencies as high as 99%. Factors such as soil type, oxidation reactions, and biodegradation rates are key to the composting process and need to be monitored and controlled for successful degradation.

Summary: This study investigated the degradation potential of trichloroethene (TCE) and the effectiveness of bioaugmentation in stimulating TCE degradation in groundwater samples from different contaminated sites. The results showed that the supply of oxygen stimulated aerobic degradation of TCE, and bioaugmentation effectively enhanced TCE degradation.

Summary: In this study, we found that bioaugmentation with aerobic, polychlorinated biphenyl (PCB) degrading microorganisms can effectively reduce PCB emissions from contaminated sediment to air. Through synthetic samples and qPCR analysis, it was observed that the total PCB mass in the bioaugmented treatment decreased by 57% on average, with a preferential biodegradation of lower-chlorinated PCBs. The use of the phytogenic biosurfactant, saponin, was also found to enhance the abundance of the degrading microorganisms and promote the biodegradation process. These findings demonstrate that bioaugmentation can be an effective approach to reduce PCB emissions and minimize exposure risks in surrounding communities.

Summary: Increasing land degradation by high level of metal wastes is of prime concern for the global research communities. Halophytes with specific features have great promise in the sustainable clean-up of contaminated sites. Physico-chemical characteristics of soil and associated microbial communities govern the clean-up efficiency of halophytes. Research on this topic has received considerable attention in recent years, with Asian and European countries leading in conducting extensive research.

Summary: In this study, we analyzed the concentrations and identities of siderophores in samples from the Northwest European shelf. We found 24 different siderophores and discovered that their impact on iron biogeochemistry is low at low concentrations, with iron bound to humic like dissolved organic matter being the dominant species.
