Detection and diversity of nitrifying and denitrifying
functional genes in coastal aquaculture.
The low level of DO observed during the anoxic phase stimulates the activity of the denitrifying
microorganisms, which results in decrease concentration of nitrate on mixed liquor at the end of the anoxic phase of this cycle.
bacteria in this long-traveled water, however, are unable to produce similar amounts of nitrogen due to a lack of nutrients in the region.
3] of a suspension of a denitrifying
organism (Pseudomonas fluorescens, [O.
By the 1880s, other chemists and biologists had worked out the basics of the nitrogen cycle, complete with roles for legumes and nitrogen-fixing, nitrifying, and denitrifying
bacteria (Leigh 2004).
bacteria obtain energy for metabolism and growth from the oxidation of reduced iron and manganese (Sarin et al.
The Piratininga-Itaipu System is a denitrifying
system, despite the fact that the presence of benthic algae on the smaller mud flats could also account for nitrogen fixation.
15]N values of pelagic sediments reveal that temporarily large parts of the Ordovician and Silurian oceans, including the photic zone, were denitrifying
Structure and activity of the denitrifying

The scientists also found that the population of denitrifying
microbes exceeded 454 million per pound of wood, compared to 45 million per pound of surface soil and 4.
Increasing activity of denitrifying
bacteria at neutral pH of soil (Pritchett, 1979) and percentage of denitrifying
