These microbial processes are important in global biogeochemical cycles such as acetogenesis, nitrification and denitrification and are critical for soil fertility.
32.
The plant's significant above-ground biomass demands the preferential uptake of nitrate over ammonia, leading to soil nitrification.
33.
Nitrite produced in the first step of autotrophic nitrification is oxidized to nitrate by nitrite oxidoreductase ( NXR ) ( 2 ).
34.
Additionally, with increasing NH 4 + accumulation in the soil, nitrification processes release hydrogen ions, which acidify the soil.
35.
Most design of RBC systems will include a minimum of 4 or 5 modules in series to obtain nitrification of waste water.
36.
It is a widely used nitrification inhibitor in agriculture as well as a soil bactericide and has been in use since 1974.
37.
The inhibition of the nitrification process is primarily facilitated by the selection and inhibition / destruction of the bacteria that oxidize ammonia compounds.
38.
They aerated the waste-water continuously for about a month and were able to achieve a complete nitrification of the sample material.
39.
In the ocean, this leads to a vertical separation of nitrification from primary production, and confines it to the aphotic zone.
40.
In 2015, two groups independently showed the microbial genus " Nitrospira " is capable of complete nitrification ( Comammox ).
