Methanogens yog microorganisms uas tsim methane raws li ib tug metabolic byproduct nyob rau hauv hypoxic tej yam kev mob. Lawv yog prokaryotic thiab belongs rau lub domain ntawm archaea. Nyob rau hauv marine sediments cov khoom siv roj ntsha ntawm methane, kuj hu ua methanogenesis , feem ntau yog nyob rau qhov twg sulfates yog depleted, hauv qab txheej saum toj kawg nkaus.
Kuj nug, vim li cas methanogens tseem ceeb?
Methanogens yog lub luag hauj lwm rau cov methane nyob rau hauv lub belches ntawm ruminants thiab nyob rau hauv lub flatulence nyob rau hauv tib neeg. Methanogens ua lub luag haujlwm tseem ceeb hauv ecological hauv ib puag ncig anaerobic los ntawm kev tshem tawm cov khoom siv hydrogen thiab fermentation uas tsim los ntawm lwm hom kev ua pa anaerobic.
Methanogens ua haujlwm li cas? Nyob rau hauv lub anaerobic digester, methanogens ua haujlwm ua ke nrog ib pawg ntawm lwm cov kab mob rau rhuav tshem cov organic pov tseg thiab tsim cov methane-muaj biogas ua cov khoom siv hluav taws xob. Ntshiab kab lis kev cai ntawm methanogens yog muaj peev xwm H2 tsim los ntawm formate thiab methane ntau lawm los ntawm thee.
Kuj paub, ua li cas methanogens ciaj sia?
Cov kab mob hauv ntiaj teb ciaj sia nyob rau hauv Martian tej yam kev mob: Methanogens nyob hauv qhov kub thiab txias heev. Methanogens , microorganisms nyob rau hauv lub npe Archaea, siv hydrogen raws li lawv lub zog qhov chaw thiab carbon dioxide raws li lawv cov pa roj carbon qhov chaw, mus metabolize thiab tsim methane, kuj hu ua natural gas.
Methanogens tau txais lub zog li cas?
Hauv qhov xwm txheej, Methanogens tau txais electrons los ntawm hydrogen thiab lwm yam molecules uas tsim thaum lub sij hawm tawg ntawm cov organic khoom los yog cov kab mob fermentation. “Lawv muab cov tshuaj methanogens nrog electrons los metabolize carbon dioxide thiab tsim methane. Hauv Spormann lab, cov tshuaj methanogens tsis tas yuav txhawj txog zaub mov.
