Summary: Petroleum refineries produce oily sludge containing hazardous polycyclic aromatic hydrocarbons (PAH), and its proper disposal is a major concern. Analyzing the physicochemical properties and functions of indigenous microbes at contaminated sites is crucial for determining the bioremediation strategy. This study examines these parameters at two geographically distant sites with different crude oil sources and compares the metabolic capability of soil bacteria based on contamination sources and site age. The results show that petroleum hydrocarbon-derived organic carbon and total nitrogen negatively impact microbial diversity.

Summary: Metagenomic or metabarcoding data are often used to predict microbial interactions in complex communities, but these predictions are rarely explored experimentally. Here, the authors combine experiments with metagenome-informed, microbial consortia-based network analyses to identify interactions in microbial consortia grown under dozens of conditions. They demonstrate the predictive power of this approach for understanding the structure and functioning of microbial communities.

Summary: In this study, a bacterial consortium C10 capable of degrading different alkyl chain lengths of phthalate plasticizers (DEHP, dibutyl phthalate, diethyl phthalate, and dimethyl phthalate) was enriched and identified in marine sediment. The major bacterial genera during degradation of the phthalate plasticizers were Gluta-micibacter, Ochrobactrum, Pseudomonas, Bacillus, Stenotrophomonas, and Methylophaga. Through a network-based approach, it was predicted that Bacillus, Stenotrophomonas, and Microbacterium cooperatively interacted as the main degraders of phthalate plasticizers. Twenty isolates belonging to different bacterial genera were obtained through selective isolation techniques, and the best DEHP-degraders were identified as Steno-trophomonas acidaminiphila OR13, Microbacterium esteraromaticum OR16, Sporosarcina sp. OR19, and Cytobacillus firmus OR20. This study provides insights into the PAE-degradation capabilities of marine sediment bacteria and offers a simple approach for the prediction and isolation of potential pollutant degraders from complex bacterial communities.

Summary: Landscape patterns of phenotypic coevolution in toxic newts and their snake predators are best predicted by a combination of community and climatic variation. Prey toxicity is elevated in regions with more predator species, while predator resistance is higher in regions with more prey species. The phenotypic outcomes of coevolutionary arms races are sensitive to local ecological contexts that vary across the landscape.

Summary: In this study, an efficient and reusable composite was prepared from CTAB modified magnetic biochar, which showed improved removal performance of polystyrene and carboxylate-modified polystyrene nanoparticles from water. The removal efficiency decreased in alkaline conditions and was gradually decreased by the presence of NaCl. Phosphate ions had the biggest impact on the removal performance. Furthermore, the composite was able to remove the nanoparticles in real surface water with high efficiencies, even after multiple recycling. The removal process was mainly through aggregation rather than adsorption.

Summary: Metal pollution in Chinese agricultural soils is a significant concern, and remediation is needed for many soils. The combination of photovoltaic power generation and phytoextraction could be a novel and potential option for contaminated arable land, if they can work effectively together. A three-year field study found that shading by PV panels did not inhibit the growth or metal uptake of the hyperaccumulator plant species Sedum plumbizincicola. Phytoextraction under the PV panels effectively removed high amounts of Cd and Zn, with the hyperaccumulator taking up 3.40 and 96.2 kg ha-1 of Cd and Zn, respectively, over three seasons. This study concludes that combining soil phytoextraction with PV electricity generation can achieve soil remediation and energy production.

Summary: Chlorinated aliphatic hydrocarbons (CAHs) are potentially toxic substances that have been commonly found in contaminated environments. This study investigates the composition, function, and assembly of soil bacteria in an aged CAH-contaminated site using high-throughput sequencing analysis. The presence of organohalide-respiring bacteria (OHRB) is crucial in reducing the environmental stress of CAHs and improving the diversity and stability of the bacterial community. The findings suggest that the metabolic community in deep soil can potentially contribute to the monitored natural attenuation technology for CAH-contaminated sites.

Summary: This study provides a detailed description of the ecological process of microbial community assembly in the hyperaccumulator plant Sedum plumbizincicola. Host selection strongly influences the aggregation of the microbial community, and soil types also play a significant role. Under heavy metal pollution, the microbial community tends to form a pool dominated by Proteobacteria and Actinobacteria, which helps increase the accumulation efficiency of potentially toxic metals in S. plumbizincicola.

Summary: Vegetation restoration and microbial restoration have positive effects on the development of soil aggregates and the accumulation of soil organic carbon (SOC) in reclaimed mine soil. In a 4-year field experiment, artificial restoration and AMF inoculation were found to increase OC, TGRSP contents, and & delta;C-13 values in deep soil. Carbon flows were influenced by different restoration modes, with artificial restoration inoculated with AMF showing a pattern of carbon flow from macroaggregates to microaggregates. TGRSP content, SOC content, and & delta;C-13 value were significantly correlated, suggesting the potential association between SOC sequestration and TGRSP. Overall, artificial restoration inoculation with AMF showed great potential in promoting aggregate carbon flow and persistent SOC accumulation.

Summary: Soil bacteria play a crucial role in regulating soil carbon and nutrient cycling. However, their response to disturbance in different land-use types, particularly in alpine ecosystems, remains largely unknown. In this study, the potential of soil bacteria to influence biogeochemical processes was assessed across different land-use types on the Tibetan Plateau. The results showed that disturbance had diverse effects on soil bacterial community composition and metabolic potential. Certain bacterial taxa were found to be sensitive to disturbance, while others remained relatively stable. These findings highlight the importance of considering the effects of disturbance on soil bacteria in ecosystem management and policy decisions.
