Ukunyamezelana nobushushu kunye nokubulala iintsholongwane Iimeko zongcoliseko oluqhelekileyo lwe-microbial kwinkcubeko yeseli
Iintsholongwane eziqhelekileyo ezingcolisa iinkcubeko zeeseli ziqukaI-Escherichia coli, I-Staphylococcus aureus, igwele, ukungunda, i-mycoplasma kunye neentsholongwane. Ngawaphi amanqanaba apho ezi ntsholongwane zinokuthi zingasebenzi khona?
1) I-Escherichia coli
I-E. coliinokumelana nobushushu obuphantsi. Ukucwilisa emanzini ashushu kwi-60°C imizuzu engama-30 kwenza ukuba iintsholongwane zingasebenzi; ukufudumeza kwi-70°C malunga nemizuzu emi-3 kubulala iintsholongwane; amanzi abilayo kwi-100°C ayenza ingasebenzi kwimizuzu e-1 ukuya kwemi-3.
2) I-Staphylococcus aureus
Iiseli zezityalo ezingenazo ii-sporeS. aureuszinokumelana nobushushu obuphakathi kwaye azikwazi ukumelana nobushushu obuphezulu. Ukuhlamba ngamanzi angama-60°C imizuzu engama-30 kususa uninzi lweentsholongwane eziphilayo; unyango olukwi-70°C imizuzu eli-10 luyenza ingasebenzi ngokupheleleyo iiseli zezityalo.
3) Imvubelo
Iiseli zemvubelo zihlala ziyeka ukukhula ngaphezu kwama-47°C. Ubushushu bazo obuphezulu buqala kuma-20°C ukuya kuma-30°C, kwaye ubushushu obuphezulu bokuvubela bungama-40–42°C. Iiseli zemvubelo ziyabulawa kwimizuzu embalwa kuma-55–56°C.
4) Umngundo
Iimbotyi zisinda lula kwaye ziyazala kwiindawo ezimnyama nezifumileyo kwi-20–30°C. Ukufudumeza uninzi lweembotyi ukuya kwi-80°C kunye nokuzigcina imizuzu engama-20 kufezekisa ukubulala iintsholongwane. Nangona kunjalo, iimbotyi zembotyi (iipropagules zokuzala) azinabushushu kwaye kunzima ukuzisusa ngamanzi abilayo kwi-100°C; unyango lobushushu obuphezulu kwi-121°C malunga nemizuzu eli-10 lunokuthintela iimbotyi.
5) I-Mycoplasma
IiMycoplasma ziibhaktheriya ezilula ezingenazo iindonga zeeseli kwaye zibonwa njengezona zinto zincinci eziziphindaphindayo (ngesiqhelo ziyi-0.1–0.3 μm ububanzi). Ubushushu bazo obuphezulu bokukhula buyi-35°C, kwaye zinovelwano kakhulu kubushushu. Ukuvezwa kwi-100°C imizuzu emi-5 kuyibulala ngokupheleleyo iMycoplasma.
6) Iintsholongwane
Iintsholongwane zihlala zichaphazeleka bubushushu. Uninzi lweentsholongwane ziyayeka ukusebenza emva kwemizuzu engama-30 kwiqondo lobushushu elingama-55–60°C, kwaye imizuzwana embalwa kuphela yokubila kwiqondo lobushushu elingama-100°C yanele ukungasebenzi ngokupheleleyo.
