Evolutionary Ecology of Natural Comammox Nitrospira Populations [PDF]
mSystems, 2022 Microbes commonly exist in diverse and complex communities where species interact, and their genomic repertoires evolve over time. Our understanding of species interaction and evolution has increased during the last decades, but most studies of ...

Enrichment of Comammox and Nitrite-Oxidizing Nitrospira From Acidic Soils [PDF]
Frontiers in Microbiology, 2020 In agricultural soils fertilized with a high amount of ammonium nitrogen, the pH decreases because of the oxidation of ammonia by nitrifiers. Molecular-based analyses have revealed that members of the genus Nitrospira dominate over other nitrifiers in ...

Competition between Nitrospira spp. and Nitrobacter spp. in nitrite-oxidizing bioreactors [PDF]
Biotechnology and Bioengineering, 2006 In this work the question was addressed if in nitrite-oxidizing activated sludge systems the environmental competition between Nitrobacterspp. and Nitrospira spp., which only recently has been discovered to play a role in these systems, is affected by ...

Relevance and diversity of Nitrospira populations in biofilters of brackish RAS. [PDF]
PLoS ONE, 2013 Lithoautotrophic nitrite-oxidizing bacterial populations from moving-bed biofilters of brackish recirculation aquaculture systems (RAS; shrimp and barramundi) were tested for their metabolic activity and phylogenetic diversity.

Oxidation kinetics and inverse isotope effect of marine nitrite-oxidizing isolates [PDF]
Environmental Microbiology, 2017 Nitrification, the step-wise oxidation of ammonium to nitrite and nitrate, is important in the marine environment because it produces nitrate, the most abundant marine dissolved inorganic nitrogen (DIN) component and N-source for phytoplankton and ...

Unveiling Global Diversity of Patescibacteriota and Functional Interactions with Host Microbes. [PDF]
Adv Sci (Weinh)Patescibacteriota represents a diverse group of ultra‐small epibiotic bacteria, which is largely overlooked. By integrating ribosomal protein S3‐based community profiling with MAG‐based metabolic potential analyses, this study provides new insights into their distribution, diversity, and potential interactions with other bacteria across diverse ...

Mutualistic relationship between Nitrospira and concomitant heterotrophs [PDF]
Environmental Microbiology Reports, 2021 Summary Nitrifying chemoautotrophs support the growth of diverse concomitant heterotrophs in natural or engineered environments by supplying organic compounds. In this study, we aimed to investigate this microbial association, especially (i) to distinguish whether the relationship between nitrifying ...

Ammonium Removal in Aquaponics Indicates Participation of Comammox Nitrospira [PDF]
Current Microbiology, 2021 AbstractAquaponic systems are sustainable solutions for food production combining fish growth (aquaculture) and production of vegetables (hydroponic) in one recirculating system. In aquaponics, nitrogen-enriched wastewater from fish in the aquaculture serves as fertilizer for the plants in the hydroponics, while the nitrogen-depleted and detoxified ...

Identification and Genomic Characterization of Two Previously Unknown Magnetotactic Nitrospirae [PDF]
Frontiers in Microbiology, 2021 Magnetotactic bacteria (MTB) are a group of microbes that biomineralize membrane-bound, nanosized magnetite (Fe3O4), and/or greigite (Fe3S4) crystals in intracellular magnetic organelle magnetosomes. MTB belonging to the Nitrospirae phylum can form up to several hundreds of Fe3O4 magnetosome crystals and dozens of sulfur globules in a single cell ...
