Summary: Microbial community diversity is correlated with physical environmental stresses. This study investigated bacterial communities in thermal spring sediments and found that both species diversity and metagenomic functional diversity decrease with increasing temperatures. The relationship between the two diversities follows a power function, indicating a quantitatively different manner in which temperature stress limits both taxonomic and functional diversity of microbial communities. The study also highlights the distinct temperature ceilings of various metabolic functions.

Summary: The response of complex microbial communities to climatic fluctuations is still not well understood. This study investigated how bacterial communities in soil can respond to changes in environmental temperature through a combination of phenotypic plasticity and species sorting. The results showed that distinct communities with different phylogenetic and functional characteristics emerged at different temperatures, with K-strategist taxa favored under cooler conditions and r-strategist taxa favored under warmer conditions. The study also found that the dynamic emergence of distinct communities across a wide range of temperatures is driven by the resuscitation of latent functional diversity.

Summary: A mathematical model was constructed to analyze the energy metabolism in erythrocyte-bioreactors containing alcohol dehydrogenase and acetaldehyde dehydrogenase. These erythrocytes can convert ethanol to acetate and potentially be used for alcohol intoxication treatment. The analysis revealed that the rate of ethanol consumption by the erythrocyte-bioreactors increases until a specific threshold level of enzyme activity is reached. Beyond this threshold, the model switches to an oscillation mode, leading to the accumulation of glycolytic intermediates and the destruction of erythrocyte-bioreactors.

Summary: We developed a simple method to construct a supramolecular glycomaterial for targeted delivery of antibiotics to P. aeruginosa in a photothermally-controlled manner. The galactose-pyrene conjugate (Gal-pyr) self-assembled with graphene nanoribbon-based nanowires via pi-pi stacking to produce a supramolecular glycomaterial, which exhibited significantly enhanced binding avidity toward a galactose-selective lectin compared to Gal-pyr alone. The as-prepared glycomaterial eradicated P. aeruginosa-derived biofilms under near-infrared light irradiation by accelerating antibiotic release due to the strong photothermal effect of the nanowires.

Summary: A method of preparing magnetic, recyclable biochar with minimal pore blockage was developed by loading ultrafine magnetite onto ball milled biochar and then milling it for a second time. The deposited magnetite did not significantly wrap the biochar, resulting in a decreased sorption performance. However, the extra milling step restored the surface functional groups and specific surface areas, leading to a 93.8% recovery adsorption of 84.6 +/- 2.5 mg/L on methylene blue. The recyclability of the material was not affected, and the adsorption was driven by multiple interactions. This twice-milled magnetic biochar is highly efficient for sustainable removal of aqueous contaminants.

Summary: Phototrophic biofilms play a crucial role in shaping the molecular composition and accumulation of dissolved organic matter (DOM) in periodically flooding-drying soils. They increase the abundance of labile DOM compounds and richness of molecular formulae during growth, while decreasing the relative abundance of labile components during decomposition. These findings provide insights into the potential use of phototrophic biofilms for enhancing DOM bioactivity and soil fertility in agricultural settings.

Summary: Alpine river and lake systems on the Tibetan Plateau act as indicators and amplifiers of global climate change and play a crucial role in the carbon cycle. However, our understanding of dissolved organic matter (DOM) variation within these systems is limited. In this study, we used optical spectroscopy, ultrahigh-resolution mass spectrometry, and stable water isotopic measurements to assess the links between DOM composition and hydrological connection. Our findings reveal that hydrological conditions, including glacier melt, significantly impact DOM composition and potential biogeochemical function in surface waters on the Tibetan Plateau.

For the cathode, iminated polyaniline (iPANI) is used to achieve energetic and morphological engineering. For the anode, the iPANI@rGO-CNTs composite facilitates uniform deposition of lithium-ions, preventing dendrite growth. With the synergic effects of iPANI@rGO-CNTs nanoreactors, the prepared LSBs exhibit excellent rate capability and cycling life, potentially leading to commercialization.

Summary: One of the most unique properties of MXenes is their excellent water dispersibility and superior electrical conductivity, but their industrial-scale application is limited by costly chemical synthesis methods. In this work, MXenes were produced in a packed-bed electrochemical reactor with a simple NH4F solution as the green electrolyte, resulting in high reaction rate and minimal chemical waste. The electrochemically produced MXenes showed excellent conductivity and were applied successfully as supercapacitor electrodes, demonstrating a revolutionary green and energy-efficient route for large-scale production of MXenes.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
