Enrichment using an up-flow column reactor and community structure of marine anammox bacteria from coastal sediment.
We established an enrichment culture of marine anaerobic ammonium oxidation (anammox) bacteria using an up-flow column reactor fed with artificial sea water supplemented with nitrogen and minerals and inoculated with coastal surface sediment collected from Hiroshima Bay. After 2 months of reactor operation, simultaneous removal of NH(4)(+) and NO(2)(-) was observed, suggesting that an anammox r...
متن کاملEnrichment of marine anammox bacteria in Hiroshima Bay sediments.
Anaerobic ammonium oxidation (anammox) involves the microbiological oxidation of ammonium with nitrite as the electron acceptor and dinitrogen gas as the main product. The Scalindua species, an anammox genus that dominates natural habitats, plays an important role in catalysing the loss of nitrogen from marine environments. Until now, a few Scalindua species have been reported to be enriched fr...
متن کاملAn untapped bacterial cellulolytic community enriched from coastal marine sediment under anaerobic and thermophilic conditions.
A bacterial community with strong cellulose [filter paper (FP) and microcrystalline cellulose] degradation ability was isolated from the coastal marine environment. They were isolated under thermophilic (60 °C) and anaerobic cultivation conditions. The library of 16S rRNA gene clones revealed a total of 16 operational taxonomic units after 50 clones were surveyed. Sixty percent of the clones we...
متن کاملImpact of Seasonal Hypoxia on Activity and Community Structure of Chemolithoautotrophic Bacteria in a Coastal Sediment.
Seasonal hypoxia in coastal systems drastically changes the availability of electron acceptors in bottom water, which alters the sedimentary reoxidation of reduced compounds. However, the effect of seasonal hypoxia on the chemolithoautotrophic community that catalyzes these reoxidation reactions is rarely studied. Here, we examine the changes in activity and structure of the sedimentary chemoli...
متن کاملEnriquecimento de bactérias anaeróbias oxidadoras de amônia – Anammox Enrichment of anaerobic ammonium oxidizing bacteria – Anammox
Anaerobic ammonium-oxidizing (Anammox) bacteria were enriched from sludge collected at a conventional activated sludge system treating domestic wastewater of Belo Horizonte(MG), Brazil, employing a sequencing batch reactor (SBR). After three months of cultivation, Anammox activity was detected in the system by the consumption of stoichiometric amounts of NO2 and NH4 +. Fluorescent in situ hybri...
