Summary: The use of indigenous bacterial consortium combined with biosurfactant can enhance the bioremediation efficiency of petroleum hydrocarbon-contaminated soil, reducing the half-life of TPH and improving its bioavailability. Biosurfactant stimulates microbial activities, accelerates the biodegradation process, and serves as an effective auxiliary method for the remediation of petroleum hydrocarbon-contaminated soil.

Summary: A consortium of two biosurfactant-producing bacteria (Bacillus pumilus KS2 and Bacillus cereus R2) was developed for remediating petroleum hydrocarbon-contaminated paddy soil. The bacteria effectively degraded a wide range of aliphatic hydrocarbons and partially degraded various PAHs in the soil samples. The degradation of TPH was found to increase over time, leading to improvements in the soil's physicochemical qualities.

Summary: This study prepared co-modified biochar immobilized laccase named Fe3O4@NaBC@GA@LC and investigated its potential for remediating PAHs-contaminated soil in steel plants. Compared to free laccase treatment, Fe3O4@NaBC@GA@LC retained 60% relative activity after 50 days of incubation at room temperature and nearly 80% relative activity after five reuses. In simulated PAHs-contaminated soil treatment experiments, immobilized laccase exhibited efficient adsorption and degradation capabilities, with a removal rate of over 90% for 5-ring PAHs in 40 days. This study highlights the potential of Fe3O4@NaBC@GA@LC as a promising candidate for PAHs-contaminated soil remediation.

Summary: Microorganism-assisted phytoremediation shows potential in enhancing enzyme activity, plant growth, and metal uptake efficiency in contaminated soils. The co-application of ACT and BC consortium can be effective in reducing the phytoremediation potential and mitigating the potential human health risk from contaminated soils. Field studies are needed to further understand the interactions of consortia with soil and different plant systems in remediating multi-metal contaminated environments.

Summary: The environment and biome of coastal ecosystems face challenges posed by various human disturbances, including soil pollution. This study investigated the interactions between archaea and bacteria in coastal ecosystems, particularly in the tidal flats of Hangzhou Bay China, and their relationship with soil factors such as salinity, dissolved organic carbon, and polycyclic aromatic hydrocarbons (PAHs). The results showed that soil salinity interacted with the diversity of both bacterial and archaeal communities, while dissolved organic carbon had a significant impact on bacterial diversity and taxa. Furthermore, soil PAHs were correlated with bacterial diversity and specific bacterial genera, and there was a strong correlation between archaeal and bacterial communities.

Summary: This study demonstrated that the potent Gram-positive bacterial strains Kocuria flava and Rhodococcus pyridinivorans can efficiently degrade pyrene, with degradation rates of 53.8% and 56.2% within a 15-day incubation period under laboratory conditions. Enzyme activities and rate kinetics of degradation were also investigated, showing that these bacteria have the potential to play an active role in the remediation of hydrocarbon-contaminated sites. The study concluded that an increase in the initial concentration of pyrene will not compromise the bacteria's ability to degrade it, with no significant synergistic/inhibitive effects observed in the consortium.

Summary: This study conducted metagenomic analysis on industrially contaminated soils, revealing that the abundance of PAH degradation genes and taxa did not differ significantly between soils with different pollution levels. The most abundant taxa carrying PAH degradation genes were actinobacteria from the Terrabacteria group. In addition to well-known PAH degraders such as Gordonia and Rhodococcus, other microbes like Azoarcus, Burkholderia, and Variovorax were found to possess genes related to PAH degradation, highlighting the non-specific and multifunctional nature of metabolic pathways encoded in these microorganisms.

Summary: This study investigated the interactive relationships among PAHs, PDGs, and bacterial communities in the rhizosphere soil and rice grain in PAH-contaminated paddy soil. It was found that PAHs played a critical role in shifting community composition in both soil and rice grain, while the abundance and diversity of PDB varied between the two environments. Additionally, different keystone species were identified in the soil and rice grain, with Pseudomonas and Sphingomonas being highlighted as important bacteria associated with PAH degradation in rice grain.

Summary: Understanding the impact of soil fauna on soil aggregate dynamics is crucial for soil science, especially in tropical countries where soil erosion is a major issue. In this study, we examined the properties of soil sheeting built by two functional groups of termites and found that the stability of non-fungus growing termites' sheeting was related to the surrounding soil properties. However, the stability of fungus growing termites' sheeting did not have direct or indirect correlations with measured variables. These findings suggest that FG and non-FG termites have different functional consequences on soil aggregate stability in tropical soils.

Summary: This study applied the pyrolysis method to treat oil-contaminated soil and measured the removal efficiency of main pollutants. It also investigated the effects of temperature, treatment time, and moisture content on pyrolysis efficiency. The integrated ecotoxicity of the treated soil was evaluated using Daphnia magna and Allivibrio fischeri. Results showed that higher treatment temperatures, moisture content, and treatment times led to higher pyrolysis efficiency. The toxicity of the soil was reduced by 99% after pyrolysis, and the assessment of toxicity was more sensitive in Allivibrio fischeri than in Daphnia magna.

Summary: This study presents the application of a porous graphene oxide/polycarbonate solid phase derived from upcycled e-waste as an effective adsorbent for removing sulphonamide residuals in wastewater. The adsorbent exhibited enhanced adsorptive ability towards sulphonamides due to its nest-like structure, high surface area, and improved thermal stability. The optimal adsorption conditions were determined, and the adsorption process was found to follow pseudo-second-order kinetics and Langmuir isotherms. The waste-derived adsorbent showed comparable performance in different water matrices and could be reused for up to 4 cycles, highlighting its great potential for wastewater treatment.

Summary: The combination of UV and water-soluble Fe(III) complexes is an effective method for activating advanced oxidation processes. Fe(III)-DTPA and Fe(III)-EGTA significantly improve the rate of sulfamethazine removal in the UV/PS system. The pH range of 6 to 8 does not significantly affect the performance of UV/PS in sulfamethazine removal. The performance of Fe(III)-DTPA and Fe(III)-EGTA is comparable to that of Fe(III)-EDDS, a frequently used catalyst in UV/PS systems.

Summary: This research developed a LC-HRMS method combined with untargeted metabolomics to detect pork adulteration in beef sausages. The presence of pork in sausages was accurately differentiated using PCA and PLS-DA analysis. Chemometric models successfully predicted the level of pork in sausages. The identified metabolites can serve as good indicators for detecting pork. LC-HRMS metabolomics combined with chemometrics is a promising alternative for pork detection in sausage products.

Summary: Despite being used since the 1940s, the increasing environmental issue caused by Per- and polyfluoroalkyl substances (PFAS) has only recently gained attention. These emerging contaminants pose significant risks to both human health and the environment, and research on PFAS has grown rapidly in recent years. However, there is a lack of funding for PFAS research in Asia, leading to limited studies and understanding of these substances.

Summary: This research developed an analytical method using liquid chromatography-high-resolution mass spectrometry and chemometrics to successfully differentiate beef meatballs from those adulterated with dog meat. The combination of non-targeted metabolomics and chemometrics can detect up to 0.1% of dog meat adulteration. The study also identified the significant impact of dog meat adulteration on beta-alanine, histidine, and ether lipid metabolism. This method has the potential to serve as an alternative method for analyzing non-halal meats in halal meat products.
