Distribution and Diversity of Comammox Nitrospira in Coastal Wetlands of China

Frontiers in Microbiology, Journal Year: 2020, Volume and Issue: 11

Published: Oct. 6, 2020

Complete ammonia oxidizers (comammox), able to individually oxidize nitrate, are considered play a significant role in the global nitrogen cycle. However, distribution of comammox Nitrospira estuarine tidal flat wetland and environmental drivers affecting their abundance diversity remain unknown. Here, we present large-scale investigation on geographical along wetlands China, where were successfully detected 9 16 sampling sites. The ranged from 4.15 × 105 6.67 106 copies/g, 2.21- 5.44-folds lower than canonical oxidizers: ammonia-oxidizing bacteria (AOB) archaea (AOA). Phylogenetic analysis based alpha subunit monooxygenase encoding gene (amoA) revealed that Clade A, mainly originating upstream river inputs, accounts for more 80% Nitrospira, whereas clade B rarely detected. Comammox dominant OTUs varied within samples, showing pattern. Salinity pH most important wetlands. was further negatively correlated with high nitrite concentrations. Altogether, this study existence, driving factors ecosystems, thus providing insights into ecological niches recently discovered nitrifying consortium contributions nitrification environments.

Genomic profiling of Nitrospira species reveals ecological success of comammox Nitrospira

Microbiome, Journal Year: 2022, Volume and Issue: 10(1)

Published: Nov. 30, 2022

Abstract Background The discovery of microorganisms capable complete ammonia oxidation to nitrate (comammox) has prompted a paradigm shift in our understanding nitrification, an essential process N cycling, hitherto considered require both oxidizing and nitrite microorganisms. This intriguing metabolism is unique the genus Nitrospira , diverse taxon previously known only contain canonical oxidizers. Comammox have been detected environments; however, global view distribution, abundance, diversity species still incomplete. Results In this study, we retrieved 55 metagenome-assembled genomes (MAGs) from newly obtained publicly available metagenomes. Combined with MAGs, constitutes largest genome database date 205 representing 132 putative species, most without cultivated representatives. Mapping metagenomic sequencing reads various environments against enabled analysis distribution habitat preferences species. ’s ecological success evident as they outnumber present higher species-level richness than all examined, except for marine wastewaters samples. type environment governs large-scale biogeographical signal. We found that closely related tend occupy same habitats, phylogenetic signal preference stronger . eco-evolutionary history more complex, subclades achieving rapid niche divergence via horizontal transfer genes, including gene encoding hydroxylamine oxidoreductase, key enzyme nitrification. Conclusions Our study expands genomic inventory genus, exposes oxidizers within wide range identifies (sub)lineages comammox proposes genes involved nitrification linked separation sublineage Nitrospira.

Complete ammonia oxidization in agricultural soils: High ammonia fertilizer loss but low N₂O production

Global Change Biology, Journal Year: 2023, Volume and Issue: 29(7), P. 1984 - 1997

Published: Jan. 6, 2023

The contribution of agriculture to the sustainable development goals requires climate-smart and profitable farm innovations. Increasing ammonia fertilizer applications meet global food demands results in high agricultural costs, environmental quality deterioration, warming, without a significant increase crop yield. Here, we reported that third microbial oxidation process, complete (comammox), is contributing loss (41.9 ± 4.8%) at rate 3.53 0.55 mg N kg-1 day-1 soils around world. comammox loss, occurring mainly surface soil profiles (0-0.2 m), was equivalent bacterial (48.6 4.5%); both processes were significantly more important than archaeal (9.5 3.6%). In contrast, produced less N2 O (0.98 0.44 μg , 11.7 3.1%), comparable by (16.4 4.4%) but lower (72.0 5.1%). efficiency conversion (0.02 0.01%) evidently (0.24 0.06%) (0.16 0.04%) oxidation. increased with increasing pH values, which only physicochemical characteristic influenced abundance rates. Ammonia dominated oxidation, intense >6.5 <6.5. Our revealed plays vital role agroecosystems have been previously overlooked for long term.
