Biogeography of anaerobic ammonia-oxidizing (anammox) bacteria
Anaerobic ammonia-oxidizing (anammox) bacteria are able to oxidize ammonia and reduce nitrite to produce N2 gas. After being discovered in a wastewater treatment plant (WWTP), anammox bacteria were subsequently characterized in natural environments, including marine, estuary, freshwater, and terrestrial habitats. Although anammox bacteria play an important role in removing fixed N from both eng...
متن کاملAmmonia Oxidizing Bacteria in Industrial Waste Water
Denaturing Gradient Gel Electrophoresis is a influential and feasible device for sequence examination of the variety of complicted natural microbial populations. For PCR amplification of 16S rDNA products and specific primers were used and analyzed by denaturing gel electrophoresis in gradient. Probes specific for the cluster Genusand were designed to bind to sequences within the region amplifi...
متن کاملShort-term effects of biomass burning on soil ammonia-oxidizing bacteria and ammonia-oxidizing archaea
Biomass burning, a form of disturbance in soil ecosystem, is frequently carried out in farmland after harvest in China, which has potential influence on soil biological properties. To study the short-term effects of biomass burning on soil ammonia-oxidizing bacteria (AOB) and archaea (AOA), a field investigation utilizing poplar branch (PB) and corn stalk (CS) as feedstock for experimental biom...
متن کاملEmergent macrophytes act selectively on ammonia-oxidizing bacteria and archaea.
Ammonia-oxidizing bacteria (AOB) and archaea (AOA) were quantified in the sediments and roots of dominant macrophytes in eight neutral to alkaline coastal wetlands. The AOA dominated in most samples, but the bacterial-to-archaeal amoA gene ratios increased with increasing ammonium levels and pH in the sediments. For all plant species, the ratios increased on the root surface relative to the adj...
متن کاملAmmonia effect on hydrogenotrophic methanogens and syntrophic acetate-oxidizing bacteria.
Ammonia-rich substrates can cause inhibition on anaerobic digestion process. Syntrophic acetate-oxidizing bacteria (SAOB) and hydrogenotrophic methanogens are important for the ammonia inhibitory mechanism on anaerobic digestion. The roles and interactions of SAOB and hydrogenotrophic methanogens to ammonia inhibition effect are still unclear. The aim of the current study was to determine the a...
