In the biological nitrogen cycle, nitrite oxidation is performed by bacteria, of which Nitrospira widespread and diverse. Communities were collected at 25-1500 m depths in South China Sea. Phylogenetic diversity, community composition, environmental factors investigated using high-throughput sequencing targeting nxrB gene statistical analyses. The composition varied spatially depth. Among 24 OTUs with relatively high abundance, 70% unclassified not affiliated known genus, suggesting a previously unrecognized diversity marine Nitrospira. Five genera detected, common marina was dominant species, whereas Candidatus lenta defluvii dominated shallow habitats. Comammox nitrosa discovered ecosystem. niche differentiation versatile species mainly shaped nitrate, temperature, DO.

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.

Microplastics (MPs) are 1-5 mm plastic particles that serious global contaminants distributed throughout marine ecosystems. However, their impact on intertidal sediment microbial communities is poorly understood. In this study, we conducted a 30-day laboratory tidal microcosm experiment to investigate the effects of MPs communities. Specifically, used biodegradable polymers polylactic acid (PLA) and polybutylene succinate (PBS), as well conventional polyethylene terephthalate (PET), polycarbonate (PC), (PE). Treatments with different concentrations (1-5%, w/w) PLA- PE-MPs were also included. We analyzed taxonomic variations in archaeal bacterial using 16S rRNA high-throughput sequencing. PLA-MPs at 1% (w/w) rapidly altered microbiome composition. Total organic carbon nitrite nitrogen key physicochemical factors urease was major enzyme shaping MP-exposed Stochastic processes predominated assembly addition enhanced contribution ecological selections. The keystone taxa archaea bacteria Nitrososphaeria Alphaproteobacteria, respectively. exposure had less effect functions while cycling decreased treatments.
