Qhov Tseem Ceeb - Mesophiles vs Thermophiles
Cov kab mob yog ib pawg ntawm cov kab mob uas vam meej hauv yuav luag txhua qhov chaw. Lawv yog cov kab mob prokaryotic nrog cov qauv me me heev. Cov kab mob tuaj yeem raug cais raws li qhov sib txawv xws li cov qauv, cov metabolism, thiab cov khoom ntawm tes. Cov kab mob tuaj yeem muab faib ua tsib chav sib txawv hu ua Psychrophiles, Psychrotrophs, Mesophiles, Thermophiles, thiab Hyperthermophiles raws li qhov zoo tshaj plaws kev loj hlob. Qhov sib txawv tseem ceeb ntawm mesophiles thiab thermophiles yog tias mesophiles nyob hauv qhov kub nruab nrab thaum cov thermophiles nyob hauv qhov kub thiab txias. Txhua tus kab mob muaj peb qhov kub thiab txias hu ua yam tsawg kawg nkaus, zoo tshaj plaws thiab siab tshaj plaws. Qhov zoo tshaj plaws kub ntawm mesophiles yog 37 0 C thaum qhov zoo tshaj plaws ntawm thermophiles yog 50 0 C.
Mesophiles yog dab tsi?
Mesophiles yog cov kab mob uas loj hlob zoo tshaj plaws nyob rau hauv nruab nrab kub. Lawv tsis tuaj yeem nyob hauv qhov kub thiab txias (qhov txias dhau los lossis kub dhau). Lawv qhov kub thiab txias nyob nruab nrab ntawm 20 0 C txog 45 0 C. Qhov kub zoo tshaj plaws ntawm mesophile yog 37 0C.
Mesophilic kab mob yog suav tias yog cov decomposers zoo tshaj plaws hauv av. Lawv kuj koom nrog hauv cov zaub mov tsis huv thiab degradation. Feem ntau cov kab mob uas pom hauv tib neeg txoj hnyuv yog mesophiles. Tib neeg lub cev kub yog 37 0 C, thiab nws yog qhov kub zoo tshaj rau kev loj hlob ntawm mesophiles. Li no, cov kab mob mesophilic yog lub luag haujlwm rau tib neeg cov kab mob feem ntau.

Dab tsi yog Thermophiles?
Thermophiles yog cov kab mob uas loj hlob zoo tshaj plaws ntawm qhov kub thiab txias. Yog li ntawd, lawv tseem hu ua cov kab mob uas nyiam sov. Lawv yog ib hom extremophiles. Thermophiles muaj nyob rau hauv ib puag ncig hnyav xws li cov av raug tshav ntuj ncaj qha, silage, compost heaps, volcanic ib puag ncig, kub springs, tob hiav txwv hydrothermal vents, thiab lwm yam. Thermophiles muaj xws li archaea thiab kab mob. Cov kab mob thermophilic yog suav tias yog cov kab mob ntxov tshaj plaws hauv ntiaj teb. Cov kab mob no muaj cov qauv ruaj khov uas tuaj yeem tiv taus qhov kub thiab txias. Lawv kuj muaj cov enzymes uas muaj cua sov. Feem ntau, cov enzymes tsis tuaj yeem ua haujlwm ntawm qhov kub thiab txias vim tias lawv yog cov protein ua kom sov. Txawm li cas los xij, lub tshav kub ruaj khov enzymes muaj los ntawm thermophiles tuaj yeem ua haujlwm ntawm qhov kub siab. Qee cov enzymes no tau siv rau hauv molecular biology (piv txwv li: Taq polymerase siv hauv PCR) thiab hauv cov tshuaj ntxuav. Thermophiles muaj daim nyias nyias uas nplua nuj nyob rau hauv saturated fatty acids. Yog li ntawd, lub membrane stability yog siab piv rau mesophiles. DNA ntawm thermophiles kuj muaj kev ruaj ntseg. Cov ntsiab lus G-C yog siab nyob rau hauv thermophiles.
Kub ntau ntawm cov thermophiles thaj tsam ntawm 45 0 C txog 80 0 C nrog qhov kub zoo tshaj ntawm 50 0 C.

Summary – Mesophiles vs Thermophiles
Mesophiles thiab thermophiles yog ob pawg ntawm cov kab mob sib cais raws li qhov kub thiab txias. Mesophiles nyob rau hauv nruab nrab kub thaum. thermophiles nyob hauv qhov kub thiab txias. Qhov no yog qhov txawv ntawm mesophiles thiab thermophiles. Tib neeg microbiome yog tsim los ntawm mesophiles vim qhov kub ntawm lub cev yog qhov zoo tshaj plaws ntawm mesophiles.
