Summary: The contribution of fungi to nitrous oxide production is recognized alongside bacteria, but the response of these groups to environmental changes, nitrogen deposition, and precipitation remains uncertain. In a temperate forest in northeastern China, soil moisture and nitrogen addition were found to have significant impacts on N2O production pathways. Bacteria dominated N2O emissions in nitrogen fertilized soil, particularly under flooded conditions, while fungi played a larger role in untreated soil at lower water-filled pore spaces.

Summary: While seed coating with fungicide is commonly used in soybean culture to control diseases, its impact on root-associated microbial communities remains understudied. This study found that fungicide seed coating had a greater effect on endophytic communities, including root endosphere and nodules, than rhizosphere communities. Many beneficial microbes responded positively to fungicide seed coating. Seed coating also increased the abundance of nitrogen fixation genes. Root-associated microbes with coatings had a higher complexity of microbial interactions. Fungicide seed coating did not show any negative impact on the root-associated microecology of mature soybean and may have a lower environmental risk than expected.

Summary: This study investigated the effects of different fertilization strategies on the abundances and community compositions of ammonia oxidizing archaea (AOA), ammonia oxidizing bacteria (AOB), and complete ammonia oxidizers (comammox Nitrospira) in a fluvo-aquic soil. The results showed that different fertilization strategies had a greater impact on the communities of AOB and comammox Nitrospira than on AOA. Fertilizer application decreased the relative abundance of Nitrosospira cluster 3b of AOB, but increased the relative abundance of Nitrosospira cluster 3a.2. Fertilizer, particularly high manure application, increased the relative abundance of comammox Nitrospira clade A.2 but decreased clade B.

Summary: Adding conductive or anti-conductive materials to the cathode of a microbial electrochemical system can selectively control the distribution of electrons between reductive dechlorination and methanogenesis. In this study, coating the cathode with NaFe enriched electroactive microorganisms and accelerated both dechlorination and methane production. BC accelerated dechlorination, while FeBC only accelerated methanogenesis. SiBC decreased electro-bioreduction but yielded the highest CH4 production. This research provides a strategy to optimize the desired outcome by choosing the appropriate conductive or anti-conductive material.

Summary: To solve nitrogen pollution in environmental water, two strains, Achromobacter sp. strain HNDS-1 and Enterobacter sp. strain HNDS-6, were isolated from acid paddy soil and identified as heterotrophic nitrifying and aerobic denitrifying strains. Both strains showed remarkable ability in removing nitrogen, with strain HNDS-1 achieving removal efficiencies of 93.31% for NH4+-N, 89.47% for NO3--N, and 100% for NO2--N when using different nitrogen resources. Genomic analysis identified key enzymes and transport proteins involved in nitrogen removal pathways. Further analysis revealed denitrification pathways of NO3-- > NO2-- > NO -> N2O -> N-2 for strain HNDS-1 and strain HNDS-6, while the nitrification pathway of NH4+ -> NO2- requires further investigation.

Summary: We discovered and studied an efficient nonradical mechanism in biochar-activated peroxydisulfate (PDS) systems. By increasing the pyrolysis temperature of biochar, we found that trichlorophenol degradation was enhanced while the production of radicals was inhibited, leading to a switch from radical-based to nonradical pathway. The nonmineralizing oxidation achieved a high electron utilization efficiency of 182%.

Summary: In this paper, we propose an innovative decentralised control framework for addressing complex systems influenced by multiple multiplicative noise factors. We refine the Riccati equation and use probabilistic state-space models to characterise the dynamic behaviours of subsystem components, ensuring optimal functionality and performance while adhering to constraints. Furthermore, we introduce a probabilistic message passing architecture to enhance system performance and promote harmonised decision-making. Through a numerical example, we demonstrate the advantages of our novel decentralised control approach in handling complex systems with multiple noise factors.

Summary: Numerous studies have shown that the soil microbiomes differ at the aggregate level, providing heterogeneous habitats for microbial communities. However, the understanding of the assembly processes and functional profiles of active bacteria in soil aggregates is limited. This study used DNA stable isotope probing and gene sequencing to investigate the diversity, assembly processes, and functional profiles of active bacteria in different-sized aggregates. The results revealed that the active bacterial community differed from the total bacterial community in terms of assembly processes and functional profiles. The study emphasizes the importance of dominant active bacteria, such as Proteobacteria, in predicting functional profiles in the soil ecosystem.

Summary: This paper proposes an optimized searching algorithm for the input weights and biases to improve the efficiency of Stochastic Configuration Network (SCN), a mathematical model used for incremental generation under supervision. The algorithm is based on an optimization model with constraints and utilizes a hybrid bat-particle swarm optimization algorithm (G-BAPSO) that uses gradient information and local adaptive adjustment mechanism for improved searching ability. Simulation results demonstrate the effectiveness of the proposed algorithm with improved network convergence rate. The G-BAPSO-SCN achieved higher training RMSE and increased recognition accuracy compared to SCN.

Summary: This study used 15N dilution and Miseq sequencing techniques to investigate the impact of fire history on soil nutrient availability, microbial traits, and gross N mineralization rates at five forest sites. The results showed that fire had both positive and negative effects on soil gross N mineralization, depending on the soil texture. Fire increased gross N mineralization rates in fine-textured soils, but decreased them in coarse-textured soils. This study provides insights into the complex mechanisms of how fire affects soil gross N mineralization in forest ecosystems.

Summary: Soil microbial community coalescence, the mixing and interaction of microbial communities, has been found to enhance the stability and complexity of rhizobacterial networks, leading to improved plant health and biomass. This study investigated the effects of different degrees of bacterial community coalescence on plant disease resistance by mixing soils from healthy and diseased habitats for watermelon planting. The results showed that mixing in more healthy soil reduced the plant disease index and increased biomass by improving the stability and complexity of the rhizobacterial network. Core taxa Nitrospirillum and Singulisphaera were enriched in the rhizosphere from healthy soils and played important roles in disease suppression and regulating the positive cohesion and modularity of the networks. Overall, these findings provide insights into the potential mechanism of microbial community coalescence for improving plant microbial community function and suggest new tools for enhancing plant fitness via soil microbiota mixing.

Summary: Collembolans, the diverse group of soil invertebrates, are affected by anthropogenic climate warming, which alters their diversity and density. In addition to abiotic stressors, changes in food availability, specifically the abundance of saprotrophic and mycorrhizal fungi, influence Collembola responses to climate warming. Collembolans prefer saprotrophic fungi but rely on mycorrhizal fungi when food sources are scarce. Understanding the mechanisms behind these dietary shifts in warm-dry and warm-wet soil conditions is crucial for predicting the impact of climate change on Collembola-fungal interactions.
