Ukubulala inzala (okanye ukuvalwa inzala) kwi-microbiology ligama elibhekiselele kuyo nayiphi na inkqubo ephelisa (esusa) okanye ebulala zonke iintlobo zobomi bemicrobial, kuqukwa neearhente ezosulelayo (ezifana nomngundo, ibhaktiriya, iintsholongwane, iifom zespore, njl. njl.) ezikhoyo kumphezulu, equlethwe kulwelo, kumayeza, okanye kwikhompawundi efana nemithombo yeendaba yezebhayoloji. Ukuvala inzala kunokufezekiswa ngokusebenzisa indibaniselwano efanelekileyo yobushushu, iikhemikhali, iradiation, uxinzelelo oluphezulu, kunye nokuhluzwa.

Ngokubanzi, izixhobo zotyando kunye namayeza angena kwindawo esele ifile emzimbeni (njengomsinga wegazi, okanye ukungena esikhumbeni) kufuneka abulawe inzala ukuya kwinqanaba eliphezulu loqinisekiso lobunyumba, okanye iSAL. Imizekelo yezixhobo ezinjalo ibandakanya ii-scalpels, iinaliti ze-hypodermic kunye ne-pacemakers eyenziweyo. Oku kukwabalulekile xa kusenziwa amayeza enziwa ngabazali.

Ukuvala inzala njengenkcazo kuphelisa bonke ubomi; ngelixa ucoceko kunye nokubulala iintsholongwane kuphelisa ngokukhethayo nangokuyinxenye. Zombini ucoceko kunye nokubulala iintsholongwane kunciphisa inani lezinto ezichongiweyo ze-pathogenic ukuya kwinto ethathwa njengamanqanaba "amkelekileyo" - amanqanaba apho umzimba usempilweni ngokufanelekileyo, ungaguqukiyo, unokujongana nawo. Umzekelo wolu didi lwenkqubo yiPasteurization.

Phakathi kweendlela zokuvala inzala sinazo:
- Ukuvala ubushushu
- Ukuvala inzala ngemichiza
- Ukuvala inzala ngemitha
- Ukuhluzwa okungenazintsholongwane
