The sequencing batch reactor as a powerful tool for the study of slowly growing anaerobic ammonium-oxidizing microorganisms
Abstract Currently available microbiological techniques are not designed to deal with very slowly growing microorganisms. The enrichment and study of such organisms demands a novel experimentalExpand
Key Physiology of Anaerobic Ammonium Oxidation
ABSTRACT The physiology of anaerobic ammonium oxidizing (anammox) aggregates grown in a sequencing batch reactor was investigated quantitatively. The physiological pH and temperature ranges were 6.7Expand
Missing lithotroph identified as new planctomycete
With the increased use of chemical fertilizers in agriculture, many densely populated countries face environmental problems associated with high ammonia emissions. The process of anaerobic ammoniaExpand
Archaeal nitrification in the ocean
Marine Crenarchaeota are the most abundant single group of prokaryotes in the ocean, but their physiology and role in marine biogeochemical cycles are unknown. Recently, a member of this clade wasExpand
A microbial consortium couples anaerobic methane oxidation to denitrification
Modern agriculture has accelerated biological methane and nitrogen cycling on a global scale. Freshwater sediments often receive increased downward fluxes of nitrate from agricultural runoff andExpand
Nitrite-driven anaerobic methane oxidation by oxygenic bacteria
Only three biological pathways are known to produce oxygen: photosynthesis, chlorate respiration and the detoxification of reactive oxygen species. Here we present evidence for a fourth pathway,Expand
Anaerobic ammonium oxidation by anammox bacteria in the Black Sea
The availability of fixed inorganic nitrogen (nitrate, nitrite and ammonium) limits primary productivity in many oceanic regions. The conversion of nitrate to N2 by heterotrophic bacteriaExpand
Molecular evidence for genus level diversity of bacteria capable of catalyzing anaerobic ammonium oxidation.
Recently, a bacterium capable to oxidize ammonium anaerobically at a high rate was identified as novel member of the Planctomycetales (Strous, M., Fuersi, J. A., Kramer, E. H. M., Logemann, S.,Expand
Enrichment and Molecular Detection of Denitrifying Methanotrophic Bacteria of the NC10 Phylum
ABSTRACT Anaerobic methane oxidation coupled to denitrification was recently assigned to bacteria belonging to the uncultured phylum NC10. In this study, we incubated sediment from a eutrophic ditchExpand
Candidatus "Scalindua brodae", sp. nov., Candidatus "Scalindua wagneri", sp. nov., two new species of anaerobic ammonium oxidizing bacteria.
Anaerobic ammonium oxidation (anammox) is both a promising process in wastewater treatment and a long overlooked microbial physiology that can contribute significantly to biological nitrogen cyclingExpand
