Archaea yog yus muaj los ntawm lawv broad-spectrum tsis kam rau cov tshuaj tiv thaiv kab mob. Tshwj xeeb, lawv cov phab ntsa ntawm tes tsis muaj peptidoglycan, ua rau lawv tiv taus rau cov kab mob antimicrobial cuam tshuam nrog peptidoglycan biosynthesis.
Ib yam li ntawd, puas yog Archaea rhiab rau cov tshuaj tua kab mob?
Cov phab ntsa ntawm tes Archaea tsis muaj peptidoglycan. d. Archaea tsis yog rhiab heev rau qee yam tshuaj tua kab mob uas cuam tshuam rau cov kab mob, tab sis yog rhiab heev rau qee yam tshuaj tua kab mob uas cuam tshuam rau Eukarya. Archaea feem ntau nyob hauv ib puag ncig huab thiab suav nrog methanogens, huab cua halophiles, thiab hyperthermophiles.
Ib yam li ntawd, dab tsi yog qhov tshwj xeeb ntawm archaea? Archaeal hlwb muaj tshwj xeeb Cov khoom sib cais lawv los ntawm ob lub npe, Kab mob thiab Eukaryota. Archaea tau muab faib ua ntau yam paub txog phyla. Archaea reproduce asexually los ntawm binary fission, fragmentation, los yog budding; tsis zoo li cov kab mob, tsis paub hom kab mob Archaea tsim cov endospores.
Hais txog qhov no, vim li cas archaea tsis raug rau penicillin?
Nws yog ib qho enzyme uas tuaj yeem yaj cov kab mob ntawm cov phab ntsa. Archaea yog tsis yog rhiab heev rau lysozyme los yog penicillin piav.
Vim li cas Archaea tuaj yeem muaj sia nyob hauv qhov xwm txheej hnyav?
Archaea Kev vam meej nyob rau hauv ntau qhov sib txawv: kub, txias, acid, puag, salinity, siab, thiab hluav taws xob. Cov txawv ib puag ncig tej yam kev mob dhau sijhawm tau tso cai Archaea evolve nrog lawv ib puag ncig heev kom lawv yoog raws lawv thiab, qhov tseeb, muaj lub sij hawm nyuaj acclimating kom tsawg mob heev.
