Summary: This study proposed an effective method to reduce methane emissions from constructed wetlands by introducing Mn-dependent anaerobic oxidation of methane (Mn-AOM) and microbial fuel cell (MFC) technology. The results showed that combining biological methods and bioelectrochemical methods can more effectively control methane emissions from constructed wetlands. Using Mn ore as the matrix and operating MFC effectively reduced methane emissions from constructed wetlands, with higher COD removal rate obtained in CW-MFC (Mn) during the 200 days of operation.

Summary: This study investigated the removal of antimonate from synthetic wastewater using dissimilatory and sulfate-reducing pathways in anaerobic packed bed reactors. The results showed an average antimony removal of 28.4% and 58.8% for the dissimilatory and sulfate-reducing processes, respectively. Crystal forms of valentinite, struvite, and kermesite were observed in the reactors, and the phylogenetic analysis revealed differences in microbial communities between the two processes, suggesting a potential key genus involved in antimony transformation.

Summary: Urban subsurface environments are often impacted by human activities, leading to elevated levels of organic and inorganic compounds in the soil and groundwater. Microbial reactions, mineral transformations, and microbial community transitions in these environments are poorly understood. Factors such as organic acid concentration and sulfate levels can greatly impact microbial reactions in different soil layers.

Summary: The study shows that dark reduction by biological processes is as important as photochemical reduction in oxic marine water. The associated aerobic bacteria are directly involved in dark Hg2+ reduction, highlighting their importance in Hg transformation in marine environments. Double isotope tracing demonstrated the reduction of Hg2+ and re-oxidation of Hg-0 in aerobic bacteria Alteromonas spp.

Summary: This study aimed to monitor processes related to sulfate reduction microbial metabolisms, including identifying main microbial genera and their hydrogen sulfide production in the intestines of healthy and unhealthy individuals, conducting phylogenetic and cluster analysis of SRB isolates, calculating growth kinetic parameters, and analyzing relationships between SRB biomass accumulation, temperature, and pH. The results revealed differences in SRB morphotypes and hydrogen sulfide concentrations between healthy individuals and patients with colitis, indicating potential risk indicators for ulcerative colitis prevalence.

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: Sulfate-reducing bacteria (SRB) are prokaryotic microorganisms widely distributed in anoxic environments and human/animal intestines, potentially impacting intestinal diseases and environmental processes. Due to their antimicrobial resistance, bacteriophages could be an effective treatment method against SRB.

Summary: This study investigated the diversity and biogenesis contributions of sulfate-reducing bacteria in arsenic-contaminated soils from realgar deposits. Novel gene variants and families were identified, and a novel sulfate-reducing bacterium capable of reducing As(V) and sulfate efficiently was isolated. The unique microbial communities in this area were also characterized.

Summary: This study investigated the dynamics of microorganisms involved in methane production, sulfate reduction, and methylmercury transformation, revealing the interrelationship and evolution of bacteria and archaea in different reactors. Results indicated that certain bacterial and archaeal species may play roles in these processes, but further research is needed to confirm these findings.

Summary: The widely distributed marine bacterium Alteromonas sp. KD01 is capable of extracellularly reducing Hg(II) through a superoxide-dependent mechanism. The generation of superoxide by Alteromonas sp. KD01 and the role of NADH in Hg(II) reduction were demonstrated. This finding provides insights into Hg(II) reduction by superoxide in various aerobic environments.

Summary: This study investigates the energy metabolism of Acidobacteriota carrying genes for the dissimilation of sulfur compounds. The results show that these acidobacteria can switch from sulfate to oxygen reduction when transitioning from anoxic to oxic conditions. This metabolic flexibility, combined with polysaccharide degradation, expands the metabolic versatility among sulfate-reducing microorganisms.

Summary: This study investigated the microbial shift and functional interactions of AnAOB, DN, and DNRA bacteria during long-term nitrite inhibition and self-recovery in a laboratory-scale anammox bioreactor. The results showed that DN and DNRA bacteria could stabilize the nitrite concentration and contribute to system recovery under high nitrite conditions. These findings provide potential engineering solutions for maintaining a robust and efficient industrial-scale anammox process.

Summary: Secondary mineralization is a promising method for remediating cadmium pollution in sediments. Phosphate can enhance the formation of stable secondary minerals and provide a new direction for Cd immobilization. The established syntrophic system of phosphate solubilizing bacteria (PSB) and dissimilatory iron reducing bacteria (DIRB) is a prospective bioremediation technology for Cd immobilization in sediments.

Summary: The reduction of Fe(III) coupled with the oxidation of organic matter is a critical biogeochemical process in lacustrine sediments. This study revealed the changes in the diversity of culturable DIRB communities with sediment depth and found that it is influenced by the distribution of nutrients and iron (minerals).

Summary: Phytoplankton can directly and indirectly influence the biogeochemical cycling and transformations of mercury. However, the current understanding of how phytoplankton affects these processes is limited. Recent research has shown that different microalgal species and cyanobacteria contribute to the transformations and reduction of mercury, and the biomolecules released by phytoplankton also participate in abiotic reduction. However, further studies are needed to explore the underlying mechanisms and the importance of these interactions in the aquatic environment.
