Summary: The study found that high concentrations of heavy metals in contaminated tailings areas can lead to physiological changes in microbial communities, increasing respiration and improving microbial activity. However, enzyme activities and enzyme activities index were influenced by environmental factors and metal concentrations, resulting in a decrease in these parameters.

Summary: Land-use conversion has significant impacts on the geochemical and microbial properties of tropical soils. The chemical index of alteration (CIA) is found to be sensitive in reflecting the geochemical controls on microbial nutrient acquisition in tropical soils. Microbial communities adjust their nutrient acquisition strategies based on the geochemical soil properties, which can affect carbon (C) input, storage, and release in tropical soils.

Summary: The study found that seasonal fluctuations in soil labile organic carbon (LOC) in forests in the Qinling Mountains of China were influenced by carbon cycle-associated enzymatic activities and microbial communities. Environmental conditions in different seasons had a significant impact on the composition of LOC in soil, as well as on enzyme activities and microbial diversity.

Summary: This study investigated the response of root-associated bacterial microbiota to CAP dosage during the two developmental phases of rice. The results showed that CAP had little effect on bacterial diversity in bulk and rhizosphere soils, but exhibited large variability in endosphere samples.

Summary: This study used HPLC-HRMS and Compound Discoverer 3.3 to screen dimethachlon degradation products in soils. Four metabolites were confirmed, and a quantitative analysis method was developed. Dimethachlon degraded quickly with a half-life of less than 1 day in nonsterile soils, and the metabolite DCBAA had a greater impact on soil enzyme activity than the parent compound.

Summary: Different types of soils exhibit varied characteristics and reactions under PCB contamination, influenced by factors such as soil pH and organic matter content. Fluvo-aquic soil showed the highest PCB dissipation rate, while different soil types had significant impacts on soil enzyme activities and bacterial communities.

Summary: This study used high-throughput sequencing to investigate the relationships between denitrifying bacteria community structures and environmental factors, revealing dynamic changes in denitrifying bacterial abundance and diversity across different seasons and processing units. The abundance and diversity of denitrifying bacteria were strongly influenced by environmental factors such as temperature and pH.

Summary: This study investigated the changes in toxicity of petroleum-contaminated soil during microbial remediation processes. The results showed that bioremediation effectively degraded the petroleum hydrocarbon pollutants. The ecological toxicity of contaminated soil increased and then decreased during the remediation process, and wheat photosynthetic pigment content, earthworm survival rate, soil catalase activity, and relative luminescence of luminescent bacteria were good indicators of the ecological toxicity.

Summary: This study investigated the impact of ecological restoration on soil organic carbon mineralization in a degraded grassland. The results showed that planting shrubs with mixed grasses increased cumulative SOC mineralization but decreased mineralization efficiency at different soil depths. Soil depth, microbial biomass C, hot-water extractable organic C, and bacterial community composition were identified as important indicators for predicting SOC mineralization.

Summary: Soil enzymes play a significant role in the storage of soil organic carbon (SOC) and nitrogen (TN), but their relationships in aggregates, particularly in sodic-alkali agricultural fields, have been understudied. This study found that soil enzymes were heterogeneously distributed in aggregates, and their activities were closely related to SOC and TN across different aggregate sizes. Moreover, the study revealed that enzyme activities were higher in the surface layer compared to the subsurface layer, indicating the importance of biophysical processes associated with enzymes in the SOC and TN sequestration within soil aggregates.
