Summary: This study examines the diversity and composition of microbial communities in terrestrial mud volcanoes (MVs) and finds that the variation in microbial communities is influenced by distance and physiochemical factors. The results show that microbial communities differ significantly between MVs, but the differences within MVs are relatively small. Physiochemical parameters explain only a small portion of the community variance, with chloride concentration being the most influential factor. Overall, the distribution of microbial communities in terrestrial MVs is affected by multiple factors.

Summary: The study reveals significant differences in spatial distribution and assembly processes of bacterial communities between bulk and rhizosphere sediments in aquatic ecosystems. Bacterial communities in rhizosphere sediments showed higher α diversity, lower β diversity, and significantly lower spatial turnover than those in bulk sediments. These findings emphasize the importance of the rhizosphere in influencing bacterial community assembly and the role of different ecological processes in governing microbial diversity over different scales in sediment environments.

Summary: Revealing the impact of different land management practices on the spatial distribution, diversity, and community assembly of fungal sub-communities is essential for biodiversity conservation and predicting microbial change trends. This study found that anthropogenic disturbances significantly altered fungal diversity, favoring rare taxa, and resulted in differences between tilled and untilled soils in terms of fungal sub-community composition. The changes were attributed to shifts in assembly processes, suggesting the potential for predicting and managing fungal sub-community changes based on land-use types.

Summary: Archaea exhibit strong community heterogeneity in biocrusts, with variations associated with spatial factors, environmental factors, and successional stages. Different regions contain unique archaeal species pools, and species tend to exchange between patches through drift. Community differences within successional stages exceed those between stages. Spatial factors have a greater impact on biogeographic patterns than environmental and successional factors, and this impact decreases with the number of species pools considered. The assembly and co-occurrence patterns of archaeal communities are associated with specific subgroups and environmental factors.

Summary: The study uncovered the mystery of the PD-anammox process in a sewage treatment plant in Xi'an, China, by analyzing the diversity and phylogenetic investigation of microbial communities in the anoxic pond. It was found that the denitrifying bacteria (DNB) content in the anoxic tank is significantly higher than the content of ammonia oxidizing bacteria (AOB), confirming the existence of a DNB-anammox system at the microbial composition level. Furthermore, genetic analysis showed that the nitrite in the anoxic pool is mainly derived from denitrification, providing a new alternative option for the mainstream application of anammox.

Summary: This study screened DMSP-catabolizing bacteria from Arctic samples and found that bacteria of four genera (Psychrobacter, Pseudoalteromonas, Alteromonas, and Vibrio) could grow with DMSP as the sole carbon source, among which Psychrobacter and Pseudoalteromonas are predominant. The DMSP catabolic pathways of these strains were proposed based on genomic and biochemical analyses. Bioinformatic analysis indicated that most Psychrobacter and Vibrio bacteria have the potential to catabolize DMSP via the demethylation pathway.

Summary: Through analyzing the genomes of marine bacteria isolated from the Arctic and Antarctic oceans, it was found that while some bacterial operational taxonomic units (OTUs) are common to both poles, not all bacteria have the same genome at a genomic level, indicating a divergence in biogeography between the poles. The study suggests that factors such as divergence time between bacteria play a significant role in determining the genomic-level biogeography of marine microorganisms isolated from distant locations.

Summary: This study used biomagnetic effect to promote anammox process. Batch tests and long-term experiments showed that an appropriate electromagnetic field (EMF) strength can improve the nitrogen removal performance of anammox, but higher strengths can inhibit the activity of anammox bacteria. The addition of EMF with an appropriate strength greatly improved the nitrogen removal performance of granular sludge. The study also found that EMF addition can increase the relative abundance of the main anammox bacteria.

Summary: Sustainable development goal 6 focuses on efficient management of water resources, wastewater treatment, and reuse of treated wastewater. Anammox and partial nitrification (PN-anammox) has been a successful side-stream wastewater treatment process, but the involvement of other nitrogen cycle bacteria is needed. Coupling anammox with PD, DAMO, and DNRA can reduce organic matter use, greenhouse gas release, and energy consumption. This review comprehensively discusses the importance and application perspective of anammox with diverse nitrate-reducing bacteria.

Summary: Similar to denitrification and anammox, DNRA is widely distributed in natural ecosystems, but often underestimated or ignored in WWTPs. A study on a full-scale SNAD WWTP revealed the coexistence of ammonia oxidizing bacteria, anammox bacteria, nitrite oxidizing bacteria, denitrifying bacteria, and DNRA organisms, with a higher relative abundance of the DNRA functional gene. The unintended selection of DNRA in the SNAD process created an engineering inefficiency of nitrogen removal by utilizing carbon that should be allocated for denitrification.
