Summary: The anammox process is popular worldwide due to its low energy consumption and waste generation. Various pollutants in wastewater can inhibit anammox activity, and understanding their effects is crucial. Strategies to overcome the inhibitory effects of pollutants on anammox activity have been identified through research in this review.

Summary: Implementing anammox based processes in the mainstream at municipal wastewater treatment plants is challenging and requires carefully constructed control strategies. A reliable method to measure the specific anammox activity was developed and implemented in a pilot plant. The study analyzed the influence of initial nitrite and ammonium concentrations on the activity, as well as the temperature dependency.

Summary: The study demonstrates that anammox thrive under mainstream conditions and can withstand typical process disruptions, such as fluctuations in dissolved oxygen levels and temperature. Additionally, anammox activity showed good stability in response to changes in organic loading rate at bench scale and pilot scale experiments.

Summary: In this study, two laboratory-scale reactors were used to investigate the application of anammox processes in the mainstream of domestic wastewater treatment plants. The results showed that Candidatus Jettenia was the dominant genus of anammox bacteria under low nitrogen loading rates with high total nitrogen concentrations.

Summary: The study investigates the feasibility of enhancing anammox enrichment in sewage treatment through fixed biofilm. The results show that the fixed biofilm effectively maintained and enriched the anammox bacteria, benefiting the startup and steady operation of the sewage partial nitrification anammox (PNA) process.

Summary: This study developed a novel technology using a granule-based sequencing batch reactor (GSBR) to achieve simultaneous removal of dissolved methane and nitrogen. The GSBR demonstrated high-level removal rates and efficiencies for nitrogen and dissolved methane during long-term demonstration. The availability of different electron acceptors significantly affected the removal of ammonium and dissolved methane, as well as the microbial communities and functional genes. These findings expand the applications of novel n-DAMO microorganisms and provide insights into microbial cooperation and competition in granular systems.

Summary: The study found that the abrupt increase in ammonium load had a significant impact on the microbial community in the nitritation-anammox reactor, leading to a decrease in nitrogen removal efficiency to 40%. While simulation calculations suggested the efficiency should recover to 76.5% within a month, experimental data did not show any improvement.

Summary: The study evaluates the feasibility of using pH, conductivity, and oxidation reduction potential profiles for monitoring and controlling the anammox process in synthetic wastewater treatment. The results show that these parameter profiles have high accuracy and reproducibility in indicating the endpoint of the anammox reaction. Positive correlations are found between TN removal and Delta pH, Delta Cond, and Delta ORP. The slope of the conductivity curve is significantly linearly correlated with the specific anammox activity, making it a useful immediate feedback signal for inhibiting anammox activity.

Summary: In this study, the effects of an aerobic denitrifying bacterium, Acinetobacter sp. WZL728, on the performance of the anoxic/oxic membrane bioreactor (A/O-MBR) were investigated. The presence of WZL728 improved the total nitrogen removal efficiency and extended the filtration cycle of A/O-MBR. The concentration of N-acyl-homoserine lactones and the content of extracellular polymeric substances (EPS) were lower in the presence of WZL728. The abundance of bacteria associated with EPS secretion decreased while the abundance of bacteria associated with EPS degradation increased. The study also revealed a decrease in the synthesis of protein and polysaccharide within the EPS.

Summary: The study presents the design, construction, operation, and performance of a semi-batch reactor suitable for measuring gas/solid reaction rates, which operates by imposing small AC modulations of reactant gas pressure on top of a larger DC pressure background. The reactor is characterized by modular construction from off-the-shelf components, enabling easy adaptation to a variety of experimental conditions.

Summary: This study investigated natural populations of Euplotes using a single-cell microbiomic approach and found a high variability in symbiotic communities, with individual hosts harboring different sets of bacterial endosymbionts. Accessory symbionts showed large variability in affinity, and competitive exclusion was observed.
