Summary: The purpose of this study was to investigate the tolerance mechanism of anammox consortia in a microbial fuel cell (MFC) system at low temperature. The data showed that a total nitrogen removal of nearly 80% was achieved after the temperature dropped from 30°C to 15°C. The nitrogen removal rate of the system decreased by 26.3% at 15°C, indicating the impact of low temperature on the performance.

Summary: The study indicates that long-term exposure to low concentration Fe(III) can improve the nitrogen removal efficiency of the anammox process, while high Fe(III) concentrations deteriorate reactor performance. Different functional bacteria show varied responses to Fe(III) stress, with high concentrations of Fe(III) significantly altering the anammox community structure.

Summary: This study investigated the metabolism of benzene by microbes under anoxic conditions. The results showed that benzene mineralization was correlated with the enrichment of a particular Peptococcaceae phylotype, and observed a slight increase in other abundant taxa. Despite benzene being the sole organic carbon source, the microbial community remained diverse, suggesting complex interactions between different functional groups.

Summary: Changes in water regime significantly influence the microbial mechanisms that regulate soil respiration in larger soil aggregates. The shift from flooding to drying enhances microbial respiration and decreases with aggregate size. Keystone taxa in bacterial networks during flooding were Acidobacteriales, Gemmatimonadales, Anaerolineales, and Cytophagales, while during drying they were Rhizobiales, Gemmatimonadales, Sphingomonadales, and Solirubrobacterales. The shift from flooding to drying also altered fungal community composition and network properties, influencing aggregate-scale soil respiration.

Summary: The successful start-up of anaerobic ammonium oxidization (anammox) system is crucial for its application. Two different feeding patterns (pulse and constant) were studied, with pulse feeding showing quicker start-up and reaching steady state faster than constant feeding. Heterotrophs and other microorganisms play important roles in nitrogen and carbon metabolisms, while a quorum sensing system was also found in the anammox system. Complex microbial interactions such as competition, cooperation, and cross-feeding were observed and had an impact on system performance.

Summary: Lake Baikal, the deepest and most voluminous freshwater reservoir on Earth, harbors benthic microbial communities with high richness and evenness, showing distinctness from other freshwater, brackish, and marine sediment communities. The core benthic communities in Baikal are relatively stable across sites and not determined by depth or latitude. Additionally, adaptation to oligotrophy may explain the presence of marine lineages in Baikal sediments.

Summary: Microbial community succession in dryland ecosystems on the Loess Plateau of China was studied over a 30+ year period. Abundant and rare microbial subcommunities were found to shift during succession, with the rare biosphere driving changes in beta diversity. Phylogenetic changes were associated with functional traits, indicating diversity-related selection. The assembly of abundant taxa was regulated by dispersal homogenizing and ecological drift, while rare subcommunities were affected by homogeneous and variable selection processes. pH and nitrogen content were key drivers of microbial community assembly, with the rare biosphere playing a crucial role in soil processes such as C, N, and S cycling.

Summary: Deciphering the ecological role of soil communities in maintaining ecosystem functions is crucial for soil biodiversity conservation. This study investigated the niche differentiation and contributions to elemental cycles of abundant and rare microbiota in intensively fertilized agroecosystems. The results showed that rare taxa had narrower niches and weaker phylogenetic signals compared to abundant species. The assembly of abundant subcommunity was influenced by dispersal limitation and undominated processes, while the assembly of rare subcommunity was dominated by homogeneous selection process. The rare biosphere made significant contributions to soil carbon and nitrogen cycling. These findings improve our understanding of microbial diversity in response to agricultural fertilization and highlight the importance of rare taxa in sustaining agricultural ecosystem functions.

Summary: Understanding the assembly mechanism of fungal communities is crucial for conserving and managing mycobiomes. However, the factors causing a decline in fungal community size are not well understood. This study used ITS sequencing data to characterize soil fungal assembly processes at different community levels. The results showed that rhizospheric communities had reduced fungal richness during the developmental transitions of soybeans. The assembly processes were primarily controlled by dispersal limitation in both the bulk soil and rhizosphere, with variable selection and drift playing secondary roles. This study enhances our understanding of fungal community assembly and provides insights into the maintenance mechanisms of metacommunity stability.

Summary: In the natural forest soils of Taibai Mountain, soil pH is the key factor determining the distribution and abundance of microorganisms, and the arsenic content and pH of the soil determine the distribution of arsenic-metabolizing microorganisms. Arsenic-related functional genes are ubiquitous in forest soils, with the arsB gene having the highest relative abundance, followed by arsC, aoxB, arrA, arsM, and arxA genes. The distribution of arsenic-related functional genes is decoupled from the corresponding bacterial community. Soil pH, organic matter, and altitude jointly determine the diversity of arsenic-related functional genes in the two slopes of Taibai Mountain, with soil pH being a key factor.

Summary: Soil aggregates are vulnerable to agricultural intensification and are important for soil health and biogeochemical cycling. Fertilization practices impact the abundance of diazotrophic community behind soil aggregates, with organic fertilization promoting nifH gene abundance while chemical fertilization shows contrasting patterns. Organic fertilization also increases the complexity of microbial networks and the robustness of diazotrophic communities. Furthermore, the diversity and abundance of diazotrophic communities in soil microaggregates play a role in determining crop yields.

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.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. 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.
