Nitrification systems and denitrification systems are used to control ammonia levels and turn nitrate into gaseous nitrogen species. Denitrification is a biochemical process that removes nitrogen from ...

Reaction 1 converts ammonia to the intermediate, hydroxylamine, and is catalyzed by the enzyme ammonia monooxygenase. Reaction 2 converts hydroxylamine to nitrite and is catalyzed by the enyzmer ...

The major transformations of nitrogen are nitrogen fixation, nitrification, denitrification, anammox, and ammonification (Figure 1). The transformation of nitrogen into its many oxidation states ...

Recently, the research team led by Professor Wu Lifang from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, developed copper pyrazole, a novel nitrification inhibitor ...

In crops with the improved ability of biological nitrification inhibition (BNI), BNI substances secreted from the roots inhibit the nitrification process in the soil, which improves the nitrogen ...

During the microbial processes of nitrification and denitrification, nitrogen and oxygen—the components of nitrous oxide—take on subtle isotopic changes that Yu's instruments can read like a ...
