Summary: The addition of organic carbon has different effects on the performance of different partial nitrification-anammox (PNA) processes, increasing TN removal in activated sludge systems while reducing TN removal in biofilm systems. Organic carbon inhibits the activities of NOB and anammox bacteria in activated sludge systems, but promotes denitrifying bacteria activity. Biofilm systems protect anammox bacteria activity and are more conducive to their growth. Quorum sensing (QS) may affect nitrogen metabolism by regulating the activity of functional bacteria.

Summary: Anaerobic ammonium oxidation (anammox) is a low-carbon biological nitrogen removal process widely used for treating high-strength wastewater. However, the slow growth rate of anammox bacteria (AnAOB) limits the practical application of mainstream anammox treatment. This article provides a comprehensive review of the effects of environmental fluctuations on anammox systems and discusses potential strategies to enhance system stability.

Summary: Enriching anaerobic ammonium oxidation bacteria (anammox) in a membrane bioreactor (MBR) achieved a total nitrogen removal rate of 1.22 kg N/m3/ day over 280 days. Interactions between quorum sensing (QS) and microbial community development were observed, with Acyl-homoserine lactones (AHLs) detected in the MBR effluent. Adding 0.1 μM C8-HSL increased the specific anammox activity (SAA) of the biomass.

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: Shortage of anammox sludge limits the application of anammox-based processes. In this study, three reactors were established using different seed sludges. After 27 days, anammox process with the highest nitrogen removal rate of 1.17 kg N m-3 d-1 was achieved using anammox granules and activated sludge. The dominant anammox bacteria shifted from Candidatus Kuenenia to Candidatus Brocadia, and quorum sensing-based regulation contributed to the growth of anammox bacteria.

Summary: The addition of 50 mg/L nZVI in the anammox reactor was found to promote the removal of NH4+ and NO2-, increase the relative abundance of AnAOB, and enrich c-di-GMP in the microbial community. This enrichment of c-di-GMP reduced microbial motility and promoted the secretion of extracellular polymers, ultimately aiding the formation of sludge particles in the reactor.

Summary: The effects of different dissolved oxygen (DO) conditions (0.3 and 1.0 mg/L) on microbial interactions in the partial nitrification/anammox (PN/A) process were investigated. High DO concentration (1.0 mg/L) inhibited anammox bacteria activity while enhancing nitrite oxidation bacteria (NOB) activity in the PN/A reactor. The presence of 1.0 mg/L DO promoted the abundance of NOB and some heterotrophic microorganisms, while decreasing the abundance of ammonia oxidizing bacteria and anammox bacteria. The changes in microbial interactions under 1.0 mg/L DO may lead to deterioration in nitrogen removal.

Summary: This study investigated the potential microbial functions in nitrogen conversion and AHLs-based quorum sensing in the PNA process. Key functional bacteria including Candidatus_Kuenenia and Nitrosomonas were identified, and AHLs such as N-octanoyl-L-homoserine lactone were found to be synthesized by nitrogen converting microorganisms and heterotrophs. Heterotrophs were revealed to have the ability to sense and degrade AHLs during information exchange, providing insights for system optimization in the microbial community.

The results showed a high removal rate and percentage of NH4-N after long-term operation. Through batch experiments and metagenomics analysis, the main microorganisms related to nitrogen metabolism were identified, and a potential oxygen-producing microorganism was discovered. The findings suggest that the removal of NH4-N under oxygen-limited conditions might involve interactions among different microorganisms, which warrants further investigation.

This review systematically characterized two types of strategists in wastewater treatment ecosystems and provided novel strategies for selectively enriching microbial community. The selection of r-/K-strategists depends on factors such as food-to-microorganism ratio, mass transfer, cell size, and biomass morphology. Practical applications include the concept of substrate flux for selective enrichment of r-/K-strategists.

Summary: Anaerobic ethanol oxidation can be thermodynamically unfavourable under standard conditions, but can become exergonic with extracellular electron transfer (EET) through microbial redox-active proteins (RAP). This study evaluates the thermodynamic effects of the fraction of substrate degraded through EET, product feedback, distribution of electrons from EET between acetotrophic and hydrogenotrophic methanogenesis, and the redox potential of RAP on anaerobic ethanol oxidation. The results show that ethanol oxidation can occur when the redox potential is above -0.408 V with EET or when product concentration is below a certain threshold. The appropriate redox potential ranges for active acetotrophic and hydrogenotrophic methanogens were determined. The EET fraction and electron distribution were found to be key factors in maintaining biomass yields and influencing the ratio of methanogens.

Summary: Struvite recovered from wastewater contains significant amounts of fecal indicator bacteria, porcine adenoviruses, and antibiotic resistance genes, which can pose potential risks. This study investigated the co-precipitation behavior of these pathogens and genes with suspended solids (SS) and found that high-density SS contributed more to the co-precipitation than low-density SS. Furthermore, the presence of SS in struvite hindered the inactivation of bacteria and genes during drying. These findings suggest that removing high-density SS prior to struvite recovery can effectively control the co-precipitation and inactivation of pathogens and genes.

Summary: Antibiotics like tetracycline in wastewater can lead to operational failure of anaerobic digestion systems, inhibiting COD removal, causing VFAs accumulation, reducing methane production, and impacting microbial communities. CFRs performed better in COD shock loading recovery, propionate degradation, and methane production. Additionally, CFRs exhibited superior tetracycline removal capacity compared to SBRs. Biodegradation was found to be the primary pathway for tetracycline removal, and long-term tetracycline exposure affected archaea abundances and enrichment of hydrolytic-acidogenic bacteria. CFRs provided a more conducive environment for the enrichment of these microorganisms.

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.
