Qhov Tseem Ceeb Qhov txawv - Methanogens vs Methanotrophs
Environmental biology yog ib ceg tseem ceeb ntawm biology uas cuam tshuam nrog cov txheej txheem ntawm ib puag ncig. Kev koom tes ntawm cov kab mob hauv cov txheej txheem no yog qhov tseem ceeb heev vim nws ua kom cov tshuaj tiv thaiv sai thiab pab txhawb kev hloov pauv ntawm cov substrates ntawm ib daim ntawv mus rau lwm qhov. Methane (CH 4) yog lub npe hu ua lub tsev ntsuab lossis cov pa roj bio thiab nws txoj kev caij tsheb kauj vab yog tswj hwm los ntawm cov kab mob. Methanogenesis yog txheej txheem uas cov kab mob tsim cov methane los ntawm cov organic; Methanogens yog cov microorganisms koom nrog hauv cov txheej txheem no. Methane digestion yog lwm txheej txheem tseem ceeb uas methane yog siv los ntawm cov kab mob hu ua methanotrophs. Yog li, qhov sib txawv tseem ceeb ntawm methanogens thiab methanotrophs yog tias methanogens tsim methane whereas methanotrophs siv methane.
Methanogens yog dab tsi?
Methanogens yog ib pawg ntawm extremophiles uas nyob hauv ib puag ncig anaerobic nruj me ntsis raws li lawv muaj cai anaerobes. Lub xub ntiag ntawm oxygen yog tshuaj lom heev rau methanogens. Methanogens belongs rau lub npe Archea. Cov chaw nyob ntawm methanogens yog cov anaerobic digesters, cov av anoxic thiab cov plab hnyuv siab raum ntawm cov kab mob siab dua xws li ruminants lossis tib neeg. Cov txheej txheem ntawm methanogenesis muab lub zog rau kev muaj sia nyob ntawm methanogens thiab cov substrates tseem ceeb koom nrog hauv methanogenesis yog hydrogen, carbon dioxide, acetate compounds thiab C-1 compounds xws li methanol.
CO2 + 4H2 → CH4 + 2H 2O
CH3COO– + H2O → CH 4 + HCO3
Methanogens yog kev lag luam siv hauv cov txheej txheem kho dej khib nyiab, qhov twg anaerobic digestion ntawm cov organic tebchaw yog ua. Cov txheej txheem ntawm anaerobic sludge digesters siv methanogens los zom cov khib nyiab. Methanogens kuj tseem siv rau hauv cov txheej txheem ntawm Bio Gas ntau lawm qhov twg methanogenesis yog kauj ruam kawg ntawm Bio gas ntau lawm.
Daim duab 01: Methanogenesis
Piv txwv ntawm methanogens suav nrog Methanococcus, Methanobacterium.
Methanotrophs yog dab tsi?
Methanotrophs lossis Methanophiles yog methane hlub cov kab mob. Lawv feem ntau yog cov kab mob gram tsis zoo uas muaj peev xwm siv methane ua nws cov pa roj carbon thiab lub zog. Cov kab mob methanotrophic siv methane hauv ib qho enzyme catalyzed cov tshuaj tiv thaiv los tsim carbon dioxide. Cov txheej txheem no tshwm sim nyob rau hauv aerobic tej yam kev mob (nyob rau hauv lub xub ntiag ntawm oxygen) thiab enzymes hu ua methane monooxygenase koom nyob rau hauv cov tshuaj tiv thaiv txheej txheem. Cov kab mob methanotrophic tuaj yeem dhau los ua ob txoj hmoo nyob ntawm nws qhov yuav tsum tau ua thaum lub sijhawm kev zom zaub mov methane. Nyob ntawm txoj kev nws yuav siv sij hawm muaj ob hom methanotrophs li hom 1 thiab hom 2.
Piv txwv ntawm methanotrophs yog Methylomonas, Methylobacter, Methylococcus, Methylocystis thiab Methylosinus.
Daim duab 02: Methanotrophs
Methanotrophs yog siv los tswj cov qib methane hauv biosphere vim methane yog cov roj tsev ntsuab muaj zog uas ua rau muaj kuab paug nyob rau hauv daim ntawv ntawm lub ntiaj teb sov. Methanotrophs kuj tseem koom nrog hauv kev zom cov methane uas yog cov khoom kawg hauv qee cov txheej txheem kev lag luam.
Dab tsi yog qhov zoo sib xws ntawm Methanogens thiab Methanotrophs?
- Methanogens thiab Methanotrophs yog extremophiles.
- Ob leeg koom nrog kev tswj hwm thiab caij tsheb kauj vab ntawm methane.
- Lawv yog cov khoom lag luam tseem ceeb hauv kev kho cov dej khib nyiab thiab kev tswj cov khib nyiab

Summary – Methanogens vs Methanotrophs
Methanogens thiab Methanotrophs yog hom kab mob tseem ceeb ntawm cov kab mob uas pab txhawb kev sib npaug ntawm methane hauv cov xwm txheej thiab coj tus cwj pwm sib koom ua ke. Methanogens tsim methane uas yog siv los ntawm methanotrophs ua lawv cov pa roj carbon thiab lub zog. Lub tswv yim no tau siv ntxiv rau hauv cov txheej txheem kev lag luam ntawm kev tswj cov khib nyiab thiab cov dej khib nyiab thiab yog li ntawd, ib lub ntsiab lus ntawm kev tshawb fawb ntawm ib puag ncig microbiologists. Methanogens tsim methane thiab methanotrophs siv methane ua lub zog. Qhov no yog qhov sib txawv tseem ceeb ntawm methanogens thiab methanotrophs.
