Qhov sib txawv tseem ceeb ntawm obligate aerobes thiab obligate anaerobes yog lub luag haujlwm aerobes tsis tuaj yeem nyob tsis muaj oxygen thaum lub luag haujlwm anaerobes tsis tuaj yeem nyob hauv lub xub ntiag ntawm oxygen.
Cov kab mob microorganisms qhia ntau haiv neeg vim lawv muaj nyob txhua qhov chaw. Lawv hnov txawv txawv rau molecular oxygen. Muaj rau pawg loj ntawm cov kab mob raws li qhov yuav tsum tau muaj cov pa oxygen: obligate aerobes, obligate anaerobe, facultative anaerobe, aerotolerant, microaerophile, thiab capnophile. Obligate aerobes lossis nruj aerobes xav tau oxygen kom nyob thiab loj hlob. Lawv xav tau cov pa oxygen txaus kom muaj sia nyob. Hauv qhov sib piv, obligate anaerobes lossis nruj anaerobes tsis tuaj yeem nyob hauv lub xub ntiag ntawm oxygen. Lawv tuag los ntawm oxygen.
Obligate Aerobes yog dab tsi?
Obligate aerobes lossis nruj aerobes yog cov kab mob uas tsis tuaj yeem loj hlob yam tsis muaj oxygen txaus. Yog li ntawd, cov pa oxygen yog qhov tseem ceeb heev rau kev ciaj sia thiab sib npaug ntawm obligate aerobes. Lawv nqa tawm aerobic ua pa nrog lub hom phiaj ntawm oxidizing substrates thiaj li tsim tau lub zog. Oxygen yog siv los ua cov khoom siv hluav taws xob zaum kawg, thiab lawv tsim lub zog ntau dua li anaerobes.
Daim duab 01: Cov kab mob raws li kev xav tau Oxygen (1. Obligate Aerobic Bacteria, 2. Obligate Anaerobic Bacteria, 3. Facultative Bacteria, 4. Microaerophiles, 5. Aerotolerant Bacteria)
Txhua tus tsiaj, nroj tsuag, feem ntau cov fungi thiab qee cov kab mob yog obligate aerobes. Mycobacterium tuberculosis, Micrococcus luteus, Neisseria meningitides, N. gonorrheae, Pseudomonas aeruginosa, Nocardia spp, Legionellae, thiab Bacillus yog ob peb yam piv txwv ntawm obligate aerobic kab mob. Obligate aerobes yog ib qho yooj yim kom loj hlob nyob rau hauv lub chaw kuaj mob. Nyob rau hauv kab lis kev cai xeem raj, obligate aerobes loj hlob nyob ze ntawm qhov chaw.
Dab tsi yog Obligate Anaerobes?
Obligate anaerobes yog ib pawg kab mob uas tsis tuaj yeem muaj sia nyob nrog oxygen. Obligate anaerobes tuag vim oxygen lom. Lawv tsis muaj cov enzymes xws li superoxide dismutase thiab catalase uas tsim nyog los hloov cov superoxide tuag vim muaj oxygen. Thaum cov pa oxygen tam sim no, tag nrho cov haujlwm uas tshwm sim hauv lub luag haujlwm anaerobes raug tso tseg.
Obligate anaerobes tsis tas yuav muaj pa oxygen rau kev ua pa. Lawv nqa tawm anaerobic ua pa los yog fermentation thiaj li tsim tau lub zog. Thaum lub sij hawm ua pa anaerobic, lawv siv ntau hom molecules xws li sulfate, nitrate, hlau, manganese, mercury, los yog carbon monoxide ua electron txais rau kev ua pa. Qee qhov piv txwv ntawm cov kab mob anaerobic yog Actinomyces, Bacteroides, Clostridium spp, Fusobacterium spp, Porphyromonas spp, Prevotella spp, Propionibacterium spp, thiab Veillonella spp.

Cov kab mob no pom muaj nyob rau hauv ib puag ncig anaerobic xws li cov av sib sib zog nqus ntawm cov av, cov dej tseem, hauv qab dej hiav txwv tob, cov hnyuv ntawm cov tsiaj thiab cov dej kub, thiab lwm yam. Tsis tas li ntawd, obligate anaerobes nyuaj rau loj hlob thiab kawm nyob rau hauv lub chaw kuaj mob. Cov cuab yeej tshwj xeeb yog xav tau los kawm txog kev ua haujlwm anaerobes. Anaerobic thawv yog ib qho ntawm cov khoom siv feem ntau siv hauv kev tshawb fawb anaerobe obligate. Cov cuab yeej no tshem tawm cov pa oxygen los ntawm ib puag ncig sab hauv thiab ua rau nws nrog cov pa roj carbon dioxide, uas pab txhawb kev loj hlob ntawm obligate anaerobes.
Qhov txawv ntawm Obligate Aerobes thiab Obligate Anaerobes yog dab tsi?
Obligate aerobes yog cov kab mob uas xav tau cov pa oxygen txaus rau kev loj hlob thiab kev sib npaug thaum lub luag haujlwm anaerobes yog cov kab mob uas nyob hauv ib puag ncig anaerobic, thaum tsis muaj oxygen. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm obligate aerobes thiab obligate anaerobes. Obligate aerobes xav tau kom muaj oxygen ntau. Nyob rau hauv sib piv, obligate anaerobes raug tua nyob rau hauv lub xub ntiag ntawm oxygen. Tsis tas li ntawd, lub luag haujlwm aerobes nqa tawm aerobic ua pa thaum lub luag haujlwm anaerobes qhia anaerobic ua pa lossis fermentation.
Dhau li ntawm, lwm qhov sib txawv ntawm obligate aerobes thiab obligate anaerobes yog tias nyob rau hauv ib lub raj kuaj kab lis kev cai, obligate aerobes ib txwm loj hlob ze rau saum npoo ntawm kab lis kev cai raj thaum obligate anaerobes sib sau ua ke hauv qab ntawm kab lis kev cai raj.
Hauv qab no yog cov lus qhia luv luv ntawm qhov sib txawv ntawm obligate aerobes thiab obligate anaerobes.
Summary – Obligate Aerobes vs Obligate Anaerobes
Obligate aerobes xav tau oxygen kom loj hlob thiab sib npaug. Hauv qhov sib piv, obligate anaerobes nyob hauv qhov tsis muaj oxygen. Molecular oxygen yog tshuaj lom rau lub luag haujlwm anaerobes txij li tag nrho lawv cov haujlwm metabolic tsis ua haujlwm thaum muaj oxygen. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm obligate aerobes thiab obligate anaerobes. Hauv ib lub raj kab lis kev cai, peb tuaj yeem pom cov kab mob aerobic nyob rau saum npoo ntawm cov kua nruab nrab thaum obligate anaerobes nyob rau hauv qab ntawm lub raj.
