Dissimilatory 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 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...
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 کاملPolygenic analysis of ammonia-oxidizing bacteria using 16S rDNA, amoA, and amoB genes.
Finding a unique molecular marker capable of quickly providing rigorous and useful phylogenetic information would facilitate assessing the diversity of ammonia-oxidizing bacteria in environmental samples. Since only one of several available markers can be used at a time in these kinds of studies, the 16S rDNA, amoA and amoB genes were evaluated individually and then compared in order to identif...
