Umahluko phakathi kwe-nitrification kunye ne-denitrification

Yintoni i-nitrification kunye ne-denitrification?

I-nitrification kunye ne-denitrification ziinkqubo ezibalulekileyo zebhayoloji kumjikelo we-nitrogen. Initrogen yinto ebalulekileyo ebomini, kodwa ayinakusetyenziswa zizidalwa ezikwimo esemoyeni yayo. sin sufrir inguqu ethile yeekhemikhali ngaphambili.

Nitrificación

I-nitrification yinkqubo apho izinto eziphilayo ziguqula i-ammonia kunye ne-ammonium ion zibe yi-nitrates kunye ne-nitrites.

Iintlobo zebhaktheriya kwi-nitrification

Le nkqubo Iqhutywa ziintlobo ezimbini zeebhaktheriya:

• Intsholongwane ye-Ammonium-oxidizing (NOB)
• Iibhaktheriya ezifaka iNitriting (AOB)

I-NOBs iguqula i-nitrite ion kwi-nitrate, ngelixa i-AOBs i-oxidize i-ammonia kunye ne-ammonium ion kwi-nitrite ion.

Desnitrificación

I-Denitrification, inxalenye yayo, yinkqubo yokuguqula i-nitrate kunye ne-nitrites ibe yi-nitrogen enegesi, ebuyela emoyeni.

Iintlobo zebhaktheriya kwi-denitrification

Iibhaktheriya ezenza i-denitrification zi-anaerobes ezisebenzayo, oko kuthetha ukuba Banokuhlala kwindawo eneoksijini okanye ngaphandle kwayo. Le nkqubo iqhutywa ziintlobo ezine zebhaktheriya:

• Pseudomonas denitrificans
• Paracoccus denitrificans
• Bacillus
• Micrococcus

I-Denitrification ibaluleke kakhulu kuba ilawula inani le-nitrate eseleyo emhlabeni nasemanzini, ukuthintela ukungcoliseka kwe-eutrophic.

Izigqibo

Isishwankathelo, i-nitrification kunye ne-denitrification ziinkqubo zebhayoloji ezihambelanayo ezenzekayo kwindalo kwaye zibaluleke kakhulu ekulawuleni isixa kunye nokufumaneka kwenitrogen, into ebalulekileyo ebomini.
