Qhov sib txawv tseem ceeb ntawm Aerobic thiab Anaerobic Microorganisms yog qhov xav tau ntawm cov pa oxygen rau cov kab mob aerobic ciaj sia thaum nws tsis yog rau cov kab mob anaerobic. Ntawd yog, cov kab mob aerobic xav tau oxygen raws li lawv qhov kawg electron txais thaum lub sij hawm ua pa aerobic thaum cov kab mob anaerobic tsis xav tau oxygen rau lawv lub cellular respiration.
Cov lus teb rau oxygen yog lub hauv paus rau kev faib cov kab mob xws li aerobic thiab anaerobic. Vim li no, cov kab mob no muaj cov yam ntxwv sib txawv los ua lawv txoj haujlwm thaum lub sijhawm ua pa ntawm tes. Yog li, aerobic microbes tau txais kev ua pa aerobic, whereas anaerobic microbes tau ua pa anaerobic.
Aerobic Microorganisms yog dab tsi?
Aerobic Microorganisms yog ib pawg ntawm cov kab mob uas cov pa oxygen ua raws li cov khoom siv hluav taws xob zaum kawg hauv kev ua pa ntawm tes. Yog li ntawd, cov microbes xav tau cov pa oxygen molecular rau nws txoj sia nyob. Lawv oxidize monosaccharides xws li qabzib nyob rau hauv lub xub ntiag ntawm oxygen. Cov txheej txheem tseem ceeb uas tsim lub zog hauv aerobes yog glycolysis, ua raws li Krebs lub voj voog thiab cov saw hlau thauj hluav taws xob. Raws li cov pa oxygen tsis muaj tshuaj lom rau cov kab mob no, lawv loj hlob zoo hauv cov xov xwm oxygenated. Thiab yog li, lawv yog obligate aerobes (Bacillus sp,)

Kev faib tawm
Microaerophilic microbes, aerotolerant microorganisms, thiab facultative anaerobes yog peb qhov kev faib tawm ntawm aerobes. Lub hauv paus ntawm qhov kev faib tawm no yog qib toxicity ntawm oxygen rau cov kab mob no.
- Cov kab mob microaerophilic - muaj sia nyob qis qis (kwv yees li 10%) ntawm cov pa oxygen (Helicobacter pylori yog cov kab mob piv txwv).
- Aerotolerant microorganisms - Lawv tsis xav tau oxygen rau nws txoj sia. Hauv qhov sib piv, muaj cov pa oxygen tsis ua mob rau cov kab mob (Lactobacillus sp yog ib qho piv txwv)
- Facultative anaerobes - Cov kab mob no tuaj yeem muaj sia nyob hauv ob qho tib si muaj thiab tsis muaj oxygen. (Escherichia coli yog facultative anaerobe)
Dab tsi yog Anaerobic Microorganisms?
Anaerobic microorganisms yog obligatory anaerobes. Lawv tsis siv oxygen raws li lawv qhov kawg electron txais. Hloov chaw, lawv siv cov substrates xws li nitrogen, methane, ferric, manganese, cob alt lossis sulfur ua lawv cov khoom siv hluav taws xob zaum kawg. Cov kab mob xws li Clostridium sp belongs rau pawg no. Tsis tas li ntawd, Anaerobes raug fermentation los tsim lub zog. Muaj ob lub ntsiab ntawm cov txheej txheem anaerobic fermentation; lactic acid fermentation thiab ethanol fermentation. Los ntawm cov txheej txheem no, anaerobes tsim lub zog (ATP), uas tsim nyog rau lawv txoj sia nyob.
Daim duab 02: Cov kab mob Anaerobic
Anaerobic microorganisms tsis muaj sia nyob hauv Oxygen-nplua nuj ib puag ncig vim tias oxygen yog tshuaj lom rau lub luag haujlwm anaerobes. Nyob rau hauv sib piv, ntau ntau cov pa oxygen tsis ua mob facultative anaerobes.
Dab tsi zoo sib xws ntawm Aerobic thiab Anaerobic Microorganisms?
- Raws li qhov xwm txheej, ob qho tib si aerobic thiab anaerobic microorganisms yog prokaryotic.
- Ob leeg cov kab mob no tau txais glycolysis, uas yog thawj kauj ruam ntawm kev ua pa ntawm tes.
- Aerobic thiab anaerobic muaj cov kab mob pathogenic-ua rau cov kab mob.
- Ob hom muaj cov microbes tseem ceeb hauv kev lag luam.
Qhov txawv ntawm Aerobic thiab Anaerobic Microorganisms yog dab tsi?

Summary – Aerobic vs Anaerobic Microorganisms
Aerobic thiab anaerobic microorganisms txawv nyob rau hauv qhov kawg electron txais. Aerobes siv molecular oxygen raws li qhov kawg electron txais. Hauv qhov sib piv, Anaerobes siv cov khoom xws li nitrates, sulfur, thiab methane ua tus txais electron kawg. Yog li ntawd, qhov sib txawv tseem ceeb ntawm aerobic thiab anaerobic microorganisms yog hom kawg electron txais lawv siv thaum lub sij hawm ua pa ntawm tes.
