Halophilic extremophiles, los yog yooj yim halophiles , yog ib pawg ntawm cov kab mob uas tuaj yeem loj hlob thiab feem ntau vam meej hauv thaj chaw siab ntsev ( NaCl ) concentration . Cov cheeb tsam no hypersaline ua tau thaj tsam ntawm salinity sib npaug rau dej hiav txwv (~ 3-5%), mus txog kaum npaug li ntawd, xws li hauv Hiav Txwv Tuag (31.5% nruab nrab ³).

Tsis tas li lo lus nug yog, lub cev twg zam qhov siab tshaj plaws ntawm NaCl?

kab mob uas muaj peev xwm ua siab ntev siab dua ntsev concentration , xws li staphylococcus, tab sis tsis xav tau cov no siab concentration rau lawv txoj kev loj hlob.

Tsis tas li ntawd, Halophiles pab tau tib neeg li cas? Halophiles yog pab tau rau ntxuav tej qhov chaw qias neeg. Cov dej khib nyiab nrog ntsev ntau dua 2% yog qhov zoo rau halophiles kom tshem tawm cov kuab paug organic los ntawm. Piv txwv li, halophiles tau pom tias tshem tawm phenol (ib qho tshuaj lom) los ntawm lawv qhov chaw.

Ib yam li ntawd, nws raug nug, Halophiles ua li cas thiaj muaj sia nyob hauv ntsev?

Lawv cov tshuab cellular tau hloov mus rau siab ntsev Cov concentrations los ntawm kev them cov amino acids ntawm lawv qhov chaw, tso cai rau khaws cov dej molecules nyob ib ncig ntawm cov khoom no. Feem ntau halophiles ua tsis tau ciaj sia sab nraum lawv lub siab- ntsev ib puag ncig ib puag ncig.

Dab tsi yog 3 hom Halophiles thiab lawv pom qhov twg?

Nyob ntawd yog peb loj Cov pab pawg paub ntawm Archaebacteria: methanogens, halophiles , thiab thermophiles. Methanogens yog cov kab mob anaerobic uas tsim methane. Lawv yog pom nyob rau hauv dej phwj kho nroj tsuag, bogs, thiab txoj hnyuv ib ntsuj av ntawm ruminants.
