Quantification of denitrifying bacteria in soils by nirK gene targeted real-time PCR.
Denitrification, the reduction of nitrate to nitrous oxide or dinitrogen, is the major biological mechanism by which fixed nitrogen returns to the atmosphere from soil and water. Microorganisms capable of denitrification are widely distributed in the environment but little is known about their abundance since quantification is performed using fastidious and time-consuming MPN-based approaches. ...

متن کاملNitrifying and denitrifying pathways of methanotrophic bacteria.
Nitrous oxide, a potent greenhouse gas and ozone-depleting molecule, continues to accumulate in the atmosphere as a product of anthropogenic activities and land-use change. Nitrogen oxides are intermediates of nitrification and denitrification and are released as terminal products under conditions such as high nitrogen load and low oxygen tension among other factors. The rapid completion and pu...
متن کاملConstruction of a consortium comprising ammonia-oxidizing bacteria and denitrifying bacteria isolated from marine sediment.
A unique consortium of ammonia-oxidizing bacteria (AOB) and denitrifying bacteria was obtained via a long-term, 3-step cultivation of isolates from organically-enriched marine sediment. We developed this microbial consortium for possible applications in the remediation of degraded habitats in closed aquaculture or other aquatic environments via microbial degradation. Analysis of media component...
متن کاملPersistence of denitrifying enzyme activity in dried soils.
The effects of air drying soil on denitrifying enzyme activity, denitrifier numbers, and rates of N gas loss from soil cores were measured. Only 29 and 16% of the initial denitrifying enzyme activity in fresh, near field capacity samples of Maury and Donerail soils, respectively, were lost after 7 days of air drying. The denitrifying activity of bacteria added to soil and activity recently form...
