Lactic acid Bacteria (lab) yog ib lo lus dav dav rau cov kab mob uas tuaj yeem tsim cov roj ntsha lactic tau siv cov roj carbohydrates ntau. Lawv tau dav pom nyob rau hauv qhov xwm, tshwj xeeb tshaj yog nyob rau hauv cov hnyuv, lub qhov ncauj, vaginas thiab lwm yam ntawm tib neeg thiab tsiaj, khoom noj mis nyuj, fermented khoom noj thiab lwm yam khoom noj.
Cov kab ke metabolic ntawm cov kab mob acids yog suav nrog cov hauv qab no:
Cov hom metabolic:Cov kab mob hauv cov kab muaj suab thaj hloov cov qab zib rau hauv lactic acid los ntawm fermentation.
Tus txheej txheem no tsis tsuas yog muab cov khoom noj uas muaj cov tsw qab thiab saj tsis tau txoj kev loj hlob ntawm cov kab mob sib txawv thiab ua lub luag haujlwm hauv kev khaws cia tshiab.
Tshuaj tua kab mob:Organic acids (such as lactic acid) produced by lactic acid bacteria metabolism exist in two states in the extracellular fluid: dissociated and undissociated.
Undissociated organic acid lwg me me tuaj yeem nkag mus rau hauv lub xov tooj ntawm tes dawb. Vim yog ib puag ncig Alkaline, cov organic acid dissocrium txav mus rau cov kev taw qhia hydrogen kev ua rau hydrogen ions thiab acid radical eions.
Cov ions tsis muaj peev xwm diffuse tawm ntawm cell los ntawm kev sib txawv dawb, yog li cov kab mob yuav tsum haus lub zog uas tau thauj khoom ntawm lub xov tooj ntawm cov chaw ruaj khov ntawm kev thauj khoom. Tsis tas li ntawd, cov organic acids kuj tseem tuaj yeem sib tw nrog cov as-ham hauv cov microorganisms, txuas ntxiv inhibiting txoj kev loj hlob ntawm kev phom sij ntawm cov kab mob sib txawv.
