Feem ntau kab mob loj hlob zoo tshaj plaws nyob rau hauv tej thaj tsam ntawm qhov kub thiab txias, thiab muaj kev tshwj xeeb kev xav tau Muaj feem xyuam rau lawv qhov kev xav tau rau huab cua, qhov tsim nyog dej, acid thiab ntsev. Los ntawm kev tswj cov as-ham, dej, kub thiab sijhawm, huab cua, acidity, thiab ntsev, koj tuaj yeem tshem tawm, tswj, lossis txo tus nqi uas kab mob loj hlob.
Ib sab ntawm no, peb lub cev tseem ceeb yog dab tsi uas yuav tsum tau muaj rau kev loj hlob ntawm cov kab mob?
Lub cev xav tau muaj xws li:
- kub. thermophiles - tshav kub hlub. mesophiles - nruab nrab kub hlub. psychrophiles - txias hlub.
- pH - acidity los yog alkalinity ntawm ib yam khoom.
Ib sab saum toj no, cov kab mob dab tsi yuav tsum tau loj hlob? Kab mob , zoo li tag nrho cov muaj sia nyob, xav tau zog thiab cov as-ham tsim cov proteins thiab cov txheej txheem membranes thiab tsav cov txheej txheem biochemical. Cov kab mob xav tau Qhov chaw ntawm carbon, nitrogen, phosphorous, hlau thiab ntau ntawm lwm cov molecules. Cov pa roj carbon, nitrogen thiab dej yog siv ntau tshaj plaws.
Raws li txoj cai, dab tsi yog lub cev xav tau rau kev loj hlob microbial?
Rau txhua tus kab mob , muaj ib txheej xwm txheej (ob leeg lub cev thiab chemical) nyob rau hauv uas nws muaj peev xwm ciaj sia. Microbes muaj ntau yam lub cev xav tau rau kev loj hlob , suav nrog qhov kub thiab txias, pH, thiab kev ntxhov siab dej.
Koj ntsuas cov kab mob loj hlob li cas?
Txoj kev yooj yim tshaj rau ntsuas cov kab mob loj hlob yog muab koj tus qauv tso rau ntawm lub iav ntshiab nyob rau hauv lub tshuab tsom iav thiab suav pes tsawg kab mob cell muaj. Xwb, koj tuaj yeem ntsuas turbidity, uas yog tus nqi ntawm kab mob hauv koj tus qauv.
