Summary: Research on the Zoige wetland of the Tibetan Plateau found that type I methanotrophs of gammaproteobacteria play a key role in methane oxidation. Additionally, two phylogenetically novel methanotroph MAGs distantly related to extant Methylobacter and Methylovulum were recovered, participating in methane oxidation via H4MPT and RuMP pathways. The study highlights the importance of methanotrophs in suppressing methane emission in the wetland under the scenario of global warming.

Summary: The present study showed that dietary supplementation of PHB did not affect the growth parameters of rainbow trout fingerlings, but significantly reduced total coliform counts and increased intestinal villus length and width. This suggests that PHB can be used as an alternative microbial control agent for improving intestinal health in rainbow trout.

Summary: This study assessed the effect of storage time on the structure and functionality of high-pressure-processed whey protein isolate (WPI), and found that the optimal treatment conditions were 400 MPa and 15 minutes for maximum unfolding and the highest hydrolysis yield. High-pressure significantly promoted the hydrolysis performances of selected enzymes towards WPI, particularly with a clear synergistic effect of alpha-chymotrypsin and bromelain combination.

Summary: This study investigated the impact of polymyxin B (PMB) on aerobic denitrification performance. The results showed that PMB decreased nitrate removal efficiency and drove denitrifiers to transform more nitrate to biomass instead of producing gas-N. PMB also damaged bacterial membrane and suppressed key enzymes participating in denitrification and aerobic respiratory chains. In addition, denitrifiers exhibited different preferences for carbon sources in the presence of PMB.

Summary: In this study, we assembled two chromosome-level genomes for wild and domestic yaks, and identified structural variants (SVs) and differentially expressed genes related to high-altitude adaptation. Additionally, the construction of a single-cell gene expression atlas revealed a yak-specific endothelial cell subtype. These findings provide new insights into the genetic and cellular basis of yak adaptation to high-altitude environments and have important implications for understanding responses to hypoxia in large mammals and humans.

Summary: Climate warming and increasing nitrogen deposition promote nitrogen and phosphorus availability in soil, affecting ecosystem structure and function. However, studies on nutrient enrichment have mainly focused on nitrogen rather than phosphorus, especially in high-altitude areas where nitrogen limits plant growth, hindering predictions of ecosystem changes under future climate conditions. This study found that phosphorus enrichment increased species richness and aboveground net primary production stability, with species asynchrony and dominant species stability driving the variation in stability. These findings highlight the importance of understanding the balance between nitrogen and phosphorus effects on ecosystem structure and function for predicting the impacts of global change on ecosystem stability.

Summary: The halotolerant strain Bacillus velezensis BSA1 can produce biosurfactant and modulate the oil microbiome for enhancing oil recovery in low permeability oil reservoirs. Laboratory experiments showed that the oil recovered by B. velezensis BSA1 was 21.6 +/- 1.87 %. Field application also demonstrated successful results with a cumulative oil production of more than 500 m3 within 12 months. Monitoring of the microbial community in the reservoir revealed an increase in surfactant-producing bacteria and hydrocarbon-degrading bacteria, contributing to the enhancement of oil recovery.

Summary: Microbial enhanced oil recovery (MEOR) is a promising method for sustainable oil production. This study reveals the existence of alternative stable states in an oil reservoir and explores the correlation between microbiota status and oil production increment. The introduction of biosurfactant-producing bacteria triggers a shift in microbiota status, resulting in higher oil recovery. The hysteresis of the microbial community requires frequent introduction of functional microbes to sustainably improve oil recovery.

Summary: This study comprehensively characterized the dissolved organic matter (DOM) in alpine meadow soil using spectroscopy and mass spectrometry, and simulated the impact of climate warming using open-top chambers (OTCs). The results showed that climate warming had different effects on DOM at different soil depths, with significant changes in the upper and lower layers and minimal changes in the middle layer. Soil nutrients and pH were identified as key factors influencing the molecular composition of DOM.

Summary: Microorganisms are involved in the biogeochemical cycling of arsenic (As), transforming As between different forms and oxidation states. Methylation of As is enhanced by microbes in paddy soil, resulting in the formation of dimethylarsenic (DMAs), which can cause rice straighthead disease. In this study, we found that methanogenic archaea, particularly Methanomassiliicoccus, play a crucial role in demethylating pentavalent DMAs.

Summary: In recent years, taste and odor (T&O) compounds in drinking water have become a serious problem, leading to challenges in drinking water treatment plants. Researchers have proposed various abiotic and biotic methods to ensure the quality of drinking water by removing T&O compounds. This review paper summarizes the process parameters, advantages and disadvantages, removal efficiency, and mechanism of these methods. It also provides a summary of the possible degradation pathways for geosmin (GSM) and 2-methylisoborneol (2-MIB), the most common odorous substances in drinking water. Furthermore, suggestions and approaches are given for efficient and safe strategies in treating T&O compounds and their future applications.

Summary: This review examines the impacts of climate change and human activities on grasslands in the Qinghai-Tibetan Plateau. It discusses the changes in vegetation and soil, as well as the drivers behind these changes. The study finds that rising temperatures have been key in driving vegetation increases, while intense livestock grazing has caused grassland degradation. Effective restoration can be achieved through management policies and adaptive management, leading to improvements in net primary production.
