Evolutionary relationships among ammonia- and nitrite-oxidizing bacteria.
Comparative 16S rRNA sequencing was used to evaluate phylogenetic relationships among selected strains of ammonia- and nitrite-oxidizing bacteria. All characterized strains were shown to be affiliated with the proteobacteria. The study extended recent 16S rRNA-based studies of phylogenetic diversity among nitrifiers by the comparison of eight strains of the genus Nitrobacter and representatives...
متن کاملDissimilatory nitrite reductase genes from autotrophic ammonia-oxidizing bacteria.
The presence of a copper-containing dissimilatory nitrite reductase gene (nirK) was discovered in several isolates of beta-subdivision ammonia-oxidizing bacteria using PCR and DNA sequencing. PCR primers Cunir3 and Cunir4 were designed based on published nirK sequences from denitrifying bacteria and used to amplify a 540-bp fragment of the nirK gene from Nitrosomonas marina and five additional ...
متن کاملCommunities of Ammonia-oxidizing Archaea and Bacteria in Enriched Nitrifying Activated Sludge
In this study, communities of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in nitrifying activated sludge (NAS) prepared by enriching sludge from a municipal wastewater treatment plant in three continuous-flow reactors receiving an inorganic medium containing different ammonium concentrations of 2, 10, and 30 mM NH4-N (NAS2, NAS10, and NAS30, respectively) were investiga...
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 کاملBiogeography 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...
