Qhov Tseem Ceeb - Lactobacillus vs Bifidobacterium
Nyob rau hauv cov ntsiab lus ntawm niaj hnub microbiology, cov kab mob sib txawv nrog kev sib koom ua ke nrog tib neeg lub cev tam sim no raug tshawb xyuas los txheeb xyuas cov txiaj ntsig sib txawv. Cov kab mob no muab cov txiaj ntsig sib txawv rau tus tswv tsev uas suav nrog kev txhim kho ntawm tus tswv tsev loj hlob thiab kev loj hlob. Lactobacillus thiab Bifidobacterium yog ob hom kab mob uas tau lees paub tias yog probiotics. Probiotics yog cov kab mob tau txais txiaj ntsig uas muaj nyob hauv plab microbiota uas muab cov txiaj ntsig sib txawv rau tus tswv tsev. Lactobacillus yog hom kab mob anaerobic facultative thaum Bifidobacterium yog ib hom kab mob anaerobic. Qhov no yog qhov sib txawv tseem ceeb ntawm Lactobacillus thiab Bifidobacterium.
YLactobacillus yog dab tsi?
Lactobacillus belongs rau pawg kab mob gram-zoo uas yog cov kab mob facultative anaerobic. Xav txog lwm yam ntawm Lactobacillus, lawv yog cov kab mob zoo li tus kab mob microaerophilic. Lawv tsis tsim ib qho spores thaum yug me nyuam. Cov kab mob no yog suav tias yog hom kab mob loj uas yog cov kab mob lactic acid. Hauv cov ntsiab lus ntawm tib neeg lub plab microbiota, Lactobacillus muaj ntau heev. Tsis yog hauv tib neeg lub plab xwb, tab sis Lactobacillus kuj nyob hauv qhov chaw xws li qhov chaw mos thiab cov zis thiab lwm yam. Nyob rau hauv cov ntsiab lus ntawm cov poj niam, tab sis Lactobacillus kuj tseem muaj nyob rau hauv qhov chaw mos microbial tseem ceeb hauv qhov chaw mos.
Cov kab mob no muaj peev xwm tsim cov biofilms hauv plab thiab qhov chaw mos thiab yog li yeej nyob rau lub sijhawm muaj teeb meem ib puag ncig. Lactobacillus tam sim no nyob rau hauv tib neeg lub cev tshwm sim raws li kev sib koom ua ke uas tiv thaiv lub cev los ntawm cov kab mob sib txawv. Tib neeg lub cev muab cov khoom noj muaj txiaj ntsig zoo rau kev loj hlob thiab kev loj hlob ntawm cov kab mob ntawm cov kab mob thiab ua kom rov ua tiav hauv lub cev. Hauv cov ntsiab lus ntawm cov khoom noj siv mis, Lactobacillus suav tias yog probiotics. Cov probiotics no txhawb tib neeg kev noj qab haus huv thiab koom nrog hauv kev kho mob raws plab thiab kab mob sib txawv ntawm qhov chaw mos. Lactobacillus kuj tseem siv tau los ua cov tswv yim kho mob rau cov kab mob ntawm daim tawv nqaij xws li eczema.
Daim duab 01: Lactobacillus
Nyob rau hauv cov ntsiab lus ntawm Lactobacillus metabolism, feem ntau ntawm cov tsiaj koom nrog hauv homofermentative metabolism, thiab ib haiv neeg tsawg koom nrog hauv heterofermentative metabolisms. Homofermentative piav qhia txog kev tsim cov lactic acid nkaus xwb los ntawm cov suab thaj thaum heterofermentative hais txog kev tsim cov lactic acid lossis cawv los ntawm cov suab thaj.
YBifidobacterium yog dab tsi?
Bifidobacterium yog ib qho uas tsis yog-mob, gram-zoo, rod-shaped (branched) obligate anaerobic kab mob uas feem ntau muaj nyob rau hauv cov hnyuv ntawm cov tsiaj thiab tib neeg. Cov kab mob no raug suav hais tias yog hom kab mob loj uas nyob hauv txoj hnyuv ntawm cov tsiaj. Zoo ib yam li Lactobacillus, Bifidobacterium kuj tseem siv los ua probiotic. Hauv cov ntsiab lus ntawm fermentation ntawm carbohydrates, Bifidobacterium siv fructose-6-phosphate phosphoketolase txoj kev. Cov kab mob no uas muaj nyob hauv tib neeg lub plab cuam tshuam nrog kev sib raug zoo nrog tus tswv tsev thiab muab cov txiaj ntsig zoo xws li kev zom zaub mov zoo, tsim cov lactic acid thiab acetic acid thiab txhawb kev tiv thaiv los ntawm kev txhawb nqa lub cev. Nws tau tshaj tawm tias Bifidobacterium muaj peev xwm los sib tw nrog lwm cov kab mob hauv plab nquag thiab tuav ib feem loj ntawm lub plab microbiota.
Daim duab 02: Bifidobacterium
Tawm ntawm pawg Bifidobacterium, Bifidobacterium longum yog hom kab mob ntau tshaj plaws. Nws muaj cov genome uas yog lub voj voog uas muaj qhov ntev ntawm 2, 260, 000 bp (pawg khub) thiab nrog GC (Guanine thiab Cytosine) cov ntsiab lus ntawm 60%. Cov hom no yog tam sim no nyob rau hauv kev tshawb fawb tag nrho txhawm rau txheeb xyuas cov txiaj ntsig probiotic. Bifidobacterium muaj txoj hauv kev tshwj xeeb rau hexose metabolism uas tau tsav los ntawm txoj kev phosphoketolase. Txoj kev tshwj xeeb no yog hu ua bifid shunt. Thaum txoj kev no, cov kab mob siv cov enzyme fructose-6-phosphate phosphoketolase. Qhov no kuj tseem siv los ua cov cuab yeej kuaj mob vim qhov tshwm sim no tsis pom nyob hauv lwm hom kab mob gram-zoo.
Dab tsi yog qhov zoo sib xws ntawm Lactobacillus thiab Bifidobacterium ?
- Lactobacillus thiab Bifidobacterium yog gram-zoo.
- Ob leeg Lactobacillus thiab Bifidobacterium tsim lactate.
- Ob qho tib si Lactobacillus thiab Bifidobacterium kab mob kis tau rau cov tshuaj tua kab mob.

Summary – Lactobacillus vs Bifidobacterium
Lactobacillus belongs rau pawg kab mob gram-zoo uas yog facultative anaerobic uas hloov cov suab thaj rau hauv lactic acid. Cov kab mob no yog suav tias yog hom kab mob loj uas yog cov kab mob lactic acid. Lactobacillus tam sim no nyob rau hauv tib neeg lub cev tshwm sim raws li kev sib koom ua ke uas tiv thaiv lub cev los ntawm cov kab mob sib txawv. Feem ntau ntawm cov hom muaj nyob rau hauv homofermentative metabolism, thiab ib tug tsawg ntawm cov tsiaj koom nyob rau hauv heterofermentative metabolisms. Cov probiotics no txhawb tib neeg kev noj qab haus huv thiab koom nrog thaum kho mob raws plab thiab kab mob sib txawv ntawm qhov chaw mos. Bifidobacterium yog ib hom kab mob uas tsis yog-motile, gram-positive, rod-shaped (branched) obligate anaerobic kab mob uas feem ntau muaj nyob rau hauv cov hnyuv ntawm cov tsiaj thiab tib neeg. Bifidobacterium muaj peev xwm sib tw nrog lwm cov kab mob hauv plab nquag thiab tuav ib feem loj ntawm plab microbiota.
