Summary: Thermokarst lagoons play an important role in the production and release of greenhouse gases. The infiltration of sulfate-rich marine water into thermokarst lagoons alters the geochemical characteristics and microbial methane-cycling community. Methane oxidation is higher in thermokarst lagoons, while methane-producing microorganisms are similar to lakes.

Summary: This paper presents the process dynamics of anaerobic oxidation of methane (AOM) coupled to sulfate reduction (SR) and the potential role of elemental sulfur as an intermediate. A dynamic model was developed to explore the interactions between biotic and abiotic processes, successfully simulating experimental data for sulfate reduction and sulfide production. The model provides a basic structure for simulating continuous flow three-phase engineered systems based on AOM-SR in the future.

Summary: ANME archaea can mediate simultaneous sulfate- and nitrate-dependent anaerobic oxidation of methane, forming a crucial link between the carbon, nitrogen, and sulfur cycles in natural environments. They collaborate with sulfate-reducing bacteria to convert sulfate to sulfide and then sulfide-oxidizing autotrophic denitrifiers to oxidize sulfide back to sulfate, thereby alleviating sulfide accumulation. The unique nanonets formed by ANME-2d and SRB likely facilitate electron transfer, highlighting the complex interactions in methane oxidation processes.

Summary: The recent discovery of anaerobic oxidation of methane (AOM) in freshwater ecosystems has sparked great interest in the "cryptic methane cycle" in terrestrial ecosystems. Although anaerobic methanotrophs are widely present in wetland ecosystems, the scope and mechanism of AOM in natural wetlands are still poorly understood. This review highlights the potential, diversity, and distribution of AOM as well as the metabolism of anaerobic methanotrophs in wetland ecosystems, aiming to unravel the biogeochemical puzzle of AOM in wetland soils.

Summary: Coastal wetlands are an important source of methane emissions. This study investigates the factors controlling methane emissions by analyzing the pore-water geochemistry in the Beidagang wetland in Tianjin, China. The results show significant spatial and temporal variability in the geochemical profile, which is influenced by changes in sulfate concentration, temperature, and dissolved oxygen. Additionally, sulfate concentration has a strong impact on sulfate reduction pathways and methane consumption.

Summary: This study investigated the phylogenetic composition and metabolic potential of prokaryotic communities in terrestrial mud volcanoes in Russia's Taman Peninsula using a metagenomic approach. A unique community containing a high abundance of ANME-3 archaea was discovered, indicating their capability of anaerobic methane oxidation. Metagenome-assembled genomes of archaeal and bacterial members were analyzed, revealing the presence of genes for methanogenesis in ANME-3 archaea and suggesting their ability to couple methane oxidation with the reduction of metal oxides or interspecies electron transfer.

Summary: This study investigates the genomic mechanisms that shape the niche partitioning among anaerobic methanotrophic (ANME) archaea in marine sediments. The results reveal that ANME-2 archaea are more prevalent in shallow sediments due to their genetic features that enhance direct interspecies electron transfer and oxygen tolerance. On the other hand, ANME-1 archaea have genetic advantages for methanogenesis and hydrogen sulfide detoxification, making them more competitive in deep layers.

Summary: Methane-dependent bioelectrochemical systems (BESs) show promise for mitigating methane emission, energy harvesting, and water environment remediation. However, the mechanisms of electron transfer from anaerobic methanotrophic (ANME) archaea/methanogens to electrodes are still poorly understood. This study found that magnetite increased the conductivity and presence of redox-active proteins in anodic biofilms primarily composed of ANME archaea/methanogens. Metagenomic analysis revealed that magnetite specifically increased the abundance of genes encoding membrane-bound proteins, which may accelerate methane oxidation and electron transfer in BESs. As a result, the current density in methane-dependent BESs with magnetite was significantly increased.

Summary: The early diagenesis of marine organic matter has a significant impact on Earth's surface chemistry, particularly in terms of carbon burial potential and the formation of authigenic minerals such as carbonate concretions. The formation of these concretions is closely related to microbial anaerobic diagenetic reactions that degrade organic matter and methane, with some reactions requiring an external oxidant. Changes in the oxidation state of Earth's oceans over time can therefore influence the mechanisms of concretion formation. Variability in the carbon isotope compositions of concretions indicates changes in diagenesis in shallow marine sediments, which is associated with the evolving redox landscape of Earth. Transport modeling helps to understand the potential effects of shifting redox chemistry and highlights the importance of organic carbon supply to the seafloor, marine sulfate concentrations, methane production, and external methane influx. The first clear evidence of anaerobic oxidation of methane-derived concretions occurred during the Carboniferous period, coinciding with the increased marine sulfate levels in the Paleozoic era. The lower variability observed in older concretions, particularly the Precambrian ones, may be attributed to a smaller marine sulfate reservoir and possibly elevated concentrations of marine dissolved inorganic carbon. The reasons behind the increase in maximum carbon isotope values over time are still not fully understood but may be related to isotopic equilibration between dissolved inorganic carbon and externally-derived methane. Ultimately, the isotopic record of concretions reflects changes in the availability of organic matter and the oxidation state of the marine environment, providing insights into the subsurface biosphere and diagenesis throughout geological time.

Summary: This study demonstrated the existence of simultaneous multi-electron acceptor-driven anaerobic oxidation of methane (AOM) in the electroactive constructed wetland environment of freshwater, which is crucial for global carbon, sulfur, nitrogen cycles and the reduction of manganese, iron, and humics. Methane emissions can effectively be controlled by multi-electron acceptor-driven AOM. Furthermore, the potential role of Mn-dependent AOM in manganese pollution removal was identified through the study of the transformation of manganese oxide in wetland manganese ore.

Summary: This study used a metataxonomic approach to uncover the microbial diversity of bacterial and fungi populations in traditionally packed Alorena de Malaga throughout its shelf-life, revealing a significant increase in lactic acid bacteria and mesophilic aerobic bacteria, and a rapid reduction in yeast and mould populations. Metataxonomic analysis based on 16S and ITS regions showed low diversity for both microbial groups, with certain genera like Lactiplantibacillus and Citeromyces dominating the bacterial and fungi populations respectively. No food-borne pathogens were detected, indicating a high level of food safety in this fermented vegetable product. Data obtained from this study can aid in designing new strategies for controlling microbial populations during the shelf-life of Alorena de Malaga.
