Antibiotics, extensively utilized in clinical infection treatment and as plant and animal husbandry growth promoters, have significantly contributed to increased life expectancy and socioeconomic progress.The emergence and rapid spread of antimicrobial resistance is of global public health concern. The gut microbiota harboring diverse commensal and opportunistic bacteria that can acquire resistance via horizontal and vertical gene transfers is considered an important reservoir and sink of anti...
Compelling evidence has shown that wetland methane emissions are more temperature dependent than carbon dioxide emissions across diverse hydrologic conditions. However, the availability of carbon substrates, which ultimately determines microbial carbon metabolism, has not been adequately acco...Wetlands store 29-45% of terrestrial soil organic carbon (SOC). Methane (CH4) and carbon dioxide (CO2) are the dominant gaseous products of wetland SOC decomposition as well as the main causes of climate change primarily characterized by global warming. Since the global warming potential of C...
In the pursuit of high crop yields, modern intensive agricultural cropping systems have generally emphasised larger inputs of nitrogen (N) and phosphorus (P) than of potassium (K).China is the world's largest consumer of chemical fertilizers, with a strong reliance on imports of mineral K fertilizer up to 50 %. Inexpensive and renewable straw-K recycling is crucial for enhancing soil K fertility and carbon (C) sequestration. Here, national management networks for inorg...
Uncontrolled ore mining and smelting operations have led to the leaching of multi-metal contaminants, resulting in heavy metal contamination of surrounding soils. For paddy fields, heavy metal contamination could result in their accumulation in rice grains and pose a major threat to human hea...Naturally-occurring colloids and nanoparticles are crucial in transporting heavy metal contaminants in soil-water systems. However, information on particle-bound metals’ size distribution and elemental composition in paddy soils under redox-fluctuation is scarce. Here, Prof. Longhua WU from ...
The extensive use and long-term discharge of PFASs have resulted in their frequent detections in a variety of environmental media, including groundwater, surface water, soil, air, organisms and human blood, both in industrial and non-industrial areas.The co-occurrence of per- and polyfluoroalkyl substances (PFASs) and chlorinated aliphatic hydrocarbons (CAHs) in groundwater has drawn increased attention in recent years. No studies have been conducted concerning the oxidative degradation of PFASs and/or CAHs by in situ thermally activated ...
Nitrogen (N), an essential element for organisms, is required for the synthesis of key cellular molecules, such as proteins and nucleic acids.Biological nitrogen fixation (BNF) driven by diazotrophs is a fundamental process underpinning the primary productivity of terrestrial ecosystems and plays a pivotal role in the global nitrogen cycle. However, the relationships between BNF function and soil diazotroph taxa with different nich...
