Nws muaj ob kauj ruam rau kev tshem tawm nitrogen hauv kev kho mob lom: nitrification thiab denitrification. Hauv cov txheej txheem no, nitrifiers, suav nrog cov kab mob ammonia-oxidizing (AOB) thiab cov kab mob nitrite-oxidizing (NOB), hloov tag nrho ammonia (dawb ammonia thiab un-ionized ammonia) rau nitrate.
txheej txheem rau kev tshem tawm nitrogen yog dab tsi?
Kev tshem tawm cov nitrogen lom yog ua tiav los ntawm nrawm nitrification nyob rau hauv aerobic tej yam kev mobthiab denitrification nyob rau hauv anoxic mob. Thaum lub sij hawm nitrification, ammonium yog oxidized rau nitrite los ntawm ammonium oxidizing kab mob (AOB) thiab ces rau nitrate los ntawm nitrite oxidizing kab mob (NOB).
