Aerobic vs Anaerobic Bacteria
Cov kab mob yog suav tias yog hom prokaryote pom nyob thoob plaws ntiaj teb. Lawv tuaj yeem muaj sia nyob yuav luag txhua qhov chaw paub hauv ntiaj teb vim lawv lub cev me me thiab muaj peev xwm loj hlob sai. Cov kab mob tuaj yeem muab faib ua ob pawg; Cov kab mob aerobic thiab anaerobic, nyob ntawm qhov cuam tshuam ntawm oxygen rau lawv txoj kev loj hlob thiab kev vam meej. Ob hom kab mob oxidize lub zog los ntawm tib txoj kev pib uas pib los ntawm kev tshem tawm ob lub hydrogen atoms los tsim C=C daim ntawv cog lus. Txawm li cas los xij, nyob rau theem tom ntej txoj kev ua ntawm ob lub hydrogen atoms sib txawv ntawm ob pawg no.
Aerobic Bacteria
Aerobes yog cov kab mob uas siv cov pa oxygen rau lawv cov tshuaj tiv thaiv metabolic. Lawv tuaj yeem tshwm sim raws li lub luag haujlwm aerobes zoo li Cholera vibrio, uas loj hlob tsuas yog nyob rau hauv lub xub ntiag ntawm oxygen, los yog nyob rau hauv raws li facultative anaerobes, uas loj hlob nyob rau hauv lub xub ntiag ntawm oxygen, tab sis muaj peev xwm zam aerobic tej yam kev mob, thiab. Qhov kawg hydrogen txais ntawm aerobes yog oxygen, uas lawv siv los oxidize lub zog qhov chaw thiab tsim carbon dioxide thiab dej raws li cov khoom kawg.
Cov kab mob feem ntau muaj qhov tseem ceeb ntawm kev kho mob yog cov kab mob facultative.
Cov kab mob anaerobic
Cov kab mob uas tsis xav tau cov pa oxygen rau lawv cov metabolism yog hu ua anaerobes. Lawv pib siv cov pa oxygen hauv cov tshuaj sib txuas rau lawv cov tshuaj tiv thaiv metabolic. Tsis zoo li aerobes, cov kab mob anaerobic tsis tuaj yeem siv cov pa oxygen molecular thiab nitrate ua cov khoom siv hluav taws xob sab nraud; Tsis tas li ntawd, lawv siv sulfate, carbon dioxide, thiab cov organic tebchaw ua lub davhlau ya nyob twg.
Muaj anaerobes hu ua obligate anaerobes, uas tsis tuaj yeem ua rau cov pa oxygen, thiab lawv feem ntau inhibited lossis tua los ntawm oxygen. Txawm li cas los xij, muaj qee qhov anaerobes xws li cov kab mob lactic acid, uas tuaj yeem ua rau cov pa oxygen ntawm qhov qub, yog li hu ua oxygen-tolerate bacteria.
Qhov txawv ntawm Aerobic thiab Anaerobic Bacteria yog dab tsi?
• Cov kab mob Aerobic xav tau oxygen rau kev loj hlob, whereas anaerobic kab mob tuaj yeem loj hlob thaum tsis muaj oxygen.
• Cov kab mob aerobic siv oxygen ua lawv qhov kawg hydrogen txais, thaum cov kab mob anaerobic tsis.
• Catalase, lub enzyme uas cais hydrogen peroxide muaj nyob rau hauv feem ntau aerobes tab sis tsis muaj nyob rau hauv anaerobes.
• Aerobes tuaj yeem ua tiav oxidize carbon zog rau dej thiab carbon dioxide siv oxygen, whereas anaerobes siv nitrates thiab sulfates es tsis txhob oxygen, li no ua gasses xws li sulfur dioxides, methane, ammonia thiab lwm yam.
• Tsis zoo li aerobes, anaerobes tsis tau txais ntau lub zog ib chav tsev ntawm substrate lawv metabolized.
