Cov kab mob aerobic yog cov kab mob uas yuav tsum muaj cov pa oxygen dawb rau lub cev. Tsis zoo li txhua lub chaw ua haujlwm, lawv tseem koom nrog txoj haujlwm ntawm kev tsim lub zog uas lawv xav tau rau cov tub ntxhais kawm. Cov kab mob no tsis muaj nucleus qhia tau. Lawv muab ntau los ntawm kev ua phom los yog sib faib thiab tsim ntau yam tshuaj lom cov khoom uas tsis tiav thaum oxidation.
Ntaus aerobics
Tsis muaj coob tus neeg paub tias cov kab mob aerobic (hauv cov lus yooj yim, aerobes) yog cov kab mob uas muaj peev xwm nyob hauv cov av, hauv huab cua, thiab hauv dej. Lawv koom tes rau hauv kev sib kis ntawm cov tshuaj thiab muaj ob peb lub tshwj xeeb enzymes uas ua kom lawv cov decomposition (piv txwv, catalase, superoxide dismutase thiab lwm tus). Kev kab mob ntawm cov kab mob no yog ua los ntawm kev siv oxidation ntawm methane, hydrogen, nitrogen, hydrogen sulfide, hlau. Lawv tuaj yeem nyob rau hauv ntau yam ntawm ib feem ntawm 0.1-20 atm.
Kev loj hlob ntawm aerobic gram-negative thiab gram-positive tus kab mob tsuas yog siv tsis tas siv cov nruab nrab kev tsim kho nruab nrab, tab sis kuj yog kev tswj ntau ntawm cov pa oxygen thiab kev cia siab ntawm qib siab. Rau txhua kab kab mob ntawm pawg neeg no muaj tsawg kawg nkaus thiab qhov siab tshaj ntawm cov pa oxygen nyob hauv cheeb tsam puag ncig nws, tsim nyog rau nws qhov kev tsim tawm thiab kev loj hlob. Yog li ntawd, ob qho kev txo thiab nce nyob rau hauv cov ntsiab lus oxygen tshaj li qhov "siab tshaj plaws" ua rau kev nkag siab ntawm kev ua si tseem ceeb ntawm tej lub microbes. Tag nrho cov kab mob aerobic tuag ntawm qhov oxygen concentration ntawm 40 mus rau 50%.
Hom mob aerobic
Los ntawm cov neeg kawm ntawv nyob ntawm seb yuav ua li cas, cov kab mob aerobic tau muab faib rau cov hom no:
1. Cov zais zis yuav tsum yog "tsis muaj cai" los yog "nruj" aerobes uas tsim tawm thaum muaj kev sib xyaw cov pa oxygen, vim lawv tau txais lub zog ntawm oxidative kev tig rov los nrog nws txoj kev koom tes. Cov no suav nrog:
- qee hom pseudomonads;
- ntau saprophytes;
- diphtheria rods;
- cholera vibrio;
- tubercle bacillus;
- cov neeg ua haujlwm ntawm cov tularemia .
2. Qhov yoojyim aerobes yog cov kab mob uas tsim muaj txawm tias qis qis dua cov pa oxygen. Pab pawg no muaj xws li:
- poov pas nrig;
- feem ntau pathogenic microbes ( meningococci , gonococci).
Thaum lawv nkag mus rau hauv qhov chaw ib txwm sab nraud, cov kab mob zoo li no yuav tsum tuag tas li, vim tias muaj ntau cov pa oxygen muaj kev cuam tshuam rau lawv txoj kev enzymes.
