Potential bacterial isolation by dosing metabolites in cross-feedings

Yunpeng Zhao et al.

Summary: Metabolic cross-feeding is crucial for bacterial growth and survival. This study demonstrated the isolation of unculturable bacteria from consortia by adding essential metabolites. Mass spectrometry imaging revealed that symbionts supplied folate and gluconate to anammox bacteria, enhancing their abundance and activity. The added metabolites reduced the metabolic burden of anammox bacteria, leading to decreased secretion of extracellular public goods and increased relative abundance.

Deciphering effects of humic acid in landfill leachate on the simultaneous nitrification, anammox and denitrification (SNAD) system from performance, electron transfer and microbial community

Yinuo Liu et al.

Summary: This study investigated the effects of humic acid (HA) on the Simultaneous nitrification, anammox and denitrification (SNAD) system for landfill leachate treatment. HA initially inhibited NH4+-N removal efficiency but the inhibition was released after system adaption. The study revealed the mechanisms of HA inhibition release, including efficient HA biodegradation, enhanced electron transfer efficiency, and improved metabolic division of microbial communities. These findings provide insights for the treatment of landfill leachate using the SNAD system.

Intensified nitrogen removal by endogenous denitrification in a full-scale municipal wastewater treatment plant

Jia Li et al.

Summary: In this study, endogenous denitrification (ED) was enhanced in a practical AAO-AO process for the first time, leading to a significant increase in nitrogen removal efficiency (NRE). The findings suggest a novel cost-and energy-efficient strategy to improve NRE by optimizing the ED process.

Exerting applied voltage promotes microbial activity of marine anammox bacteria for nitrogen removal in saline wastewater treatment

Zhi Hu et al.

Summary: This study demonstrates that the application of voltage in a bioelectrochemical system can effectively promote the activity of marine anammox bacteria in saline wastewater treatment, leading to an increase in nitrogen removal rate. The optimal voltage was found to be 1.5 V, which resulted in a 27.45% higher total nitrogen removal rate compared to without applied voltage. The study also revealed that higher voltage (>2.0 V) had a negative effect on MAB activity, but the bioactivity was recoverable after removing the high voltage.

Unveilingmicrobial community and function involved in anammox in paddy vadose under groundwater irrigation

Huai Li et al.

Summary: The extensive use of nitrogen fertilizer in intensively irrigated areas poses a potential threat to groundwater. Understanding the structure and function of microbial communities in paddy vadose under groundwater irrigation is crucial for controlling groundwater nitrogen pollution. This study found that the depth of groundwater irrigation affects microbial community structure and function, and soil properties play a role in shaping the microbial community. Deep groundwater irrigation promotes the enrichment of nitrogen-degrading bacteria, and soil nutrients and electron donors/acceptors are important factors in microbial community structure. The findings highlight the role of indigenous microorganisms in in-situ nitrogen removal and the importance of understanding microbial communities in paddy vadose under groundwater irrigation.

Potential microbial functions and quorum sensing systems in partial nitritation and anammox processes

Zhaolu Feng et al.

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.

Effect of Fe2+ addition on anammox consortia, nitrogen removal performance and functional genes analysis during start-up of anammox process

Lara Sindhu et al.

Summary: This study found that the addition of suitable Fe2+ in anammox system can significantly improve nitrogen removal efficiency and rate, as well as enhance the extracellular polymeric substance levels. Fe2+ also activates the central metabolism of anammox bacteria to promote nitrogen removal. Furthermore, Fe2+ addition increases the relative abundance of specific bacteria, affecting the efficiency of ammonium and nitrite removal.

Resistance genes and extracellular proteins relieve antibiotic stress on the anammox process

Nian-Si Fan et al.

Summary: High concentrations of antibiotics ETC and SMZ had significant inhibitory effects on the nitrogen removal performance of the anammox process, with the combined inhibitory effect being more significant. The anammox process was able to quickly recover from deterioration, possibly attributed to the increase in ARGs and secretion of EPS.
