Abstract: The microbial guild coupling anammox and nitrite/nitrate-dependent anaerobic methane oxidation (n-DAMO) is an innovative process to achieve energy-efficient nitrogen removal with the beneficial use of methane in biogas or in anaerobically treated wastewater. Here, metagenomics and metatranscriptomics were used to reveal the microbial ecology of two biofilm systems, which incorporate anammox and n-DAMO for high-level nitrogen removal in low-strength domestic sewage and high-strength sidestream wastewater, respectively. We find that different nitrogen loadings (i.e., 0.1 vs. 1.0 kg N/m 3 /d) lead to different combinations of anammox bacteria and anaerobic methanotrophs (“ Candidatus Methanoperedens” and “ Candidatus Methylomirabilis”), which play primary roles for carbon and nitrogen transformations therein. Despite methane being the only exogenous organic carbon supplied, heterotrophic populations (e.g., Verrucomicrobiota and Bacteroidota) co-exist and actively perform partial denitrification or dissimilatory nitrate reduction to ammonium (DNRA), likely using organic intermediates from the breakdown of methane and biomass as carbon sources. More importantly, two novel genomes belonging to “ Ca . Methylomirabilis” are recovered, while one surprisingly expresses nitrate reductases, which we designate as “ Ca . Methylomirabilis nitratireducens” representing its inferred capability in performing nitrate-dependent anaerobic methane oxidation. This finding not only suggests a previously neglected possibility of “ Ca . Methylomirabilis” bacteria in performing methane-dependent nitrate reduction, and also challenges the previous understanding that the methane-dependent complete denitrification from nitrate to dinitrogen gas is carried out by the consortium of bacteria and archaea.

Hot spring distribution and survival mechanisms of thermophilic comammox Nitrospira

Abstract: The recent discovery of Nitrospira species capable of complete ammonia oxidation (comammox) in non-marine natural and engineered ecosystems under mesothermal conditions has changed our understanding of microbial nitrification. However, little is known about the occurrence of comammox bacteria or their ability to survive in moderately thermal and/or hyperthermal habitats. Here, we report the wide distribution of comammox Nitrospira in five terrestrial hot springs at temperatures ranging from 36 to 80°C and provide metagenome-assembled genomes of 11 new comammox strains. Interestingly, the identification of dissimilatory nitrate reduction to ammonium (DNRA) in thermophilic comammox Nitrospira lineages suggests that they have versatile ecological functions as both sinks and sources of ammonia, in contrast to the described mesophilic comammox lineages, which lack the DNRA pathway. Furthermore, the in situ expression of key genes associated with nitrogen metabolism, thermal adaptation, and oxidative stress confirmed their ability to survive in the studied hot springs and their contribution to nitrification in these environments. Additionally, the smaller genome size and higher GC content, less polar and more charged amino acids in usage profiles, and the expression of a large number of heat shock proteins compared to mesophilic comammox strains presumably confer tolerance to thermal stress. These novel insights into the occurrence, metabolic activity, and adaptation of comammox Nitrospira in thermal habitats further expand our understanding of the global distribution of comammox Nitrospira and have significant implications for how these unique microorganisms have evolved thermal tolerance strategies.

High-level nitrogen removal by simultaneous partial nitritation, anammox and nitrite/nitrate-dependent anaerobic methane oxidation
Publisher: Elsevier BV

DOI: 10.1016/J.WATRES.2019.115057
Abstract: While the anaerobic ammonium oxidation (anammox) process has been applied for nitrogen removal from high-strength wastewater, nitrate accumulation in effluent still represents a major concern. Here, a novel process, named the one-stage PNAM, that integrates the Partial Nitritation (PN), Anammox and Methane-dependent nitrite/nitrate reduction reactions in a single membrane biofilm reactor (MBfR) is developed. With feeding of 1030 mg NH4+-N/L at a hydraulic retention time of 16 h, the proposed one-stage PNAM process achieved an average total nitrogen removal efficiency of 98% and a nitrogen removal rate of 1.5 kg N/m3/d (1.4-1.8 g N/m2/d) by using methane as the sole carbon-based electron donor. The N2O emission was determined to be 0.34% ± 0.01%. Microbial community characterization revealed that ammonia-oxidizing bacteria (AOB), anammox bacteria, nitrite/nitrate-dependent anaerobic methane oxidation (n-DAMO) bacteria and archaea co-developed in the biofilm. Batch tests showed that AOB, anammox bacteria and n-DAMO microorganisms were indeed jointly responsible for the nitrogen removal. This one-stage PNAM process can potentially be applied to treating high-strength wastewater, such as anaerobic sludge digestion liquor or landfill leachate.

Abstract: Due to serious eutrophication in water bodies, nitrogen removal has become a critical stage for wastewater treatment plants (WWTPs) over past decades. Conventional biological nitrogen removal processes are based on nitrification and denitrification (N/DN), and are suffering from several major drawbacks, including substantial aeration consumption, high fugitive greenhouse gas emissions, a requirement for external carbon sources, excessive sludge production and low energy recovery efficiency, and thus unable to satisfy the escalating public needs. Recently, the discovery of anaerobic ammonium oxidation (anammox) bacteria has promoted an update of conventional N/DN-based processes to autotrophic nitrogen removal. However, the application of anammox to treat domestic wastewater has been hindered mainly by unsatisfactory effluent quality with nitrogen removal efficiency below 80%. The discovery of nitrate/nitrite-dependent anaerobic methane oxidation (n-DAMO) during the last decade has provided new opportunities to remove this barrier and to achieve a robust system with high-level nitrogen removal from municipal wastewater, by utilizing methane as an alternative carbon source. In the present review, opportunities and challenges for nitrate/nitrite-dependent anaerobic methane oxidation are discussed. Particularly, the prospective technologies driven by the cooperation of anammox and n-DAMO microorganisms are put forward based on previous experimental and modeling studies. Finally, a novel WWTP system acting as an energy exporter is delineated.

Pilot-scale demonstration of a novel process integrating Partial Nitritation with simultaneous Anammox, Denitrification and Sludge Fermentation (PN + ADSF) for nitrogen removal and sludge reduction

DOI: 10.1016/J.SCITOTENV.2021.152835
Abstract: Anammox process is a cost-effective solution for nitrogen removal, whereas unsatisfactory effluent with nitrate accumulation is usually achieved in treating domestic sewage, owning to the unwanted prevalence of nitrite-oxidizing bacteria (NOB) and the intrinsic nitrate production by anammox bacteria. Herein, a pilot-scale system integrating Partial Nitritation and simultaneous Anammox, Denitrification and Sludge Fermentation (PN + ADSF) process was developed to treat real municipal wastewater. In this process, PN was accomplished in a sequencing batch reactor (SBR) using the strategy of intermittent hydroxylamine addition, while ADSF coupling anammox and heterotrophic denitrification was conducted in an up-flow anaerobic sludge blanket reactor (UASB) to further remove nitrogen. The pilot-scale system achieved total inorganic nitrogen (TIN) concentrations of 10.0 mg N/L in effluent and sludge reduction efficiency of 42.3% simultaneously. The characterization on microbial communities revealed that Candidatus Kuenenia and Thauera were the dominant functional bacteria for anammox and denitrification, respectively. Supported by the slow-release carbon sources from sludge fermentation, heterotrophic denitrification contributed to about 28% of nitrogen removed from the UASB, while anammox played a more important role in nitrogen removal. The pilot-scale demonstration confirmed that the PN + ADSF process is technically feasible for enhanced nitrogen removal and sludge reduction.
Microplastics can selectively enrich intracellular and extracellular antibiotic resistant genes and shape different microbial communities in aquatic systems

DOI: 10.1016/J.SCITOTENV.2022.153488
Abstract: Microplastics (MPs), as emerging contaminants, are posing potential risks to environment, and animal and human health. The ubiquitous presence of MPs in natural ecosystems provides favorable platform to selectively adsorb antibiotic resistant genes (ARGs) and bacteria (ARB) and bacterial assemblages, especially in wastewater which is hotspot for MPs, ARGs and ARB. In this study, the selective capture of intracellular ARGs (iARGs), extracellular ARGs (eARGs), and bacterial assemblages by MPs with different materials (i.e. polyethylene, polyvinylchloride, and polyethylene terephthalate) and sizes (200 μm and 100 μm) was investigated. The results showed that iARGs (i.e. i-TetA, i-TetC, i-TetO, i-sul1), integron-integrase gene (intI1), and eARGs (i.e. e-TetA and e-bla

Abstract: The occurrence of microplastics (MPs, 90% of the total MPs detected in four s ling sites, which was likely associated with their migratory routes through surface water runoff and infiltration into the groundwater settings. The results of this study suggest the importance of counting small MPs when determining their abundances in groundwater or their abundances would be considerably underestimated. The present study for the first time demonstrated the occurrence of MPs in groundwater in China, which improves our understanding of the MPs distribution and raises concerns about groundwater safety in terms of MPs pollution.
Selective enrichment and metagenomic analysis of three novel comammox Nitrospira in a urine-fed membrane bioreactor

DOI: 10.1038/S43705-021-00005-3
Abstract: The discovery of complete ammonia-oxidizing (comammox) Nitrospira has added an important new process to the microbial nitrogen cycle. While comammox Nitrospira have been detected in various ecosystems, only few studies have achieved their enrichment over other canonical nitrifiers. Here, we obtained a selective enrichment of comammox Nitrospira in a urine-fed membrane bioreactor in less than 200 days. By using 16S rRNA gene licon sequencing and quantitative PCR of the functional marker gene amoA , we observed a dominance (up to 30% relative abundance) of comammox Nitrospira over ammonia-oxidizing bacteria and archaea. Furthermore, the complete genomes of three new clade A comammox Nitrospira were recovered by metagenomics. These three strains were ergent from previously reported comammox species according to comparative genome and amoA -based analyses. In addition to the key genes for ammonia and nitrite oxidation, the three recovered genomes contained a complete urea utilization pathway. Our findings suggest that the urea present in the urine media played a significant role in the selective enrichment of these novel comammox Nitrospira , and support the ersity and versatility of their metabolism.
