Propionic acid cov kab mob, cov khoom uas yuav tau tham hauv qab no, koom ua ke los ntawm genus Propionibacterium. Nws, nyob rau hauv lem, belongs rau tsev neeg Propionibacteriaceae. Cia peb xav txog qhov nthuav dav yam ntxwv ntawm cov kab mob propionic acid muaj, qhov twg cov kab mob no tau khaws cia thiab siv.
Kev piav qhia
Cov kab mob Propoic acid yog catalase-positive, Gram-positive, non-motile, non-spore-forming aerotolerant microorganisms lossis facultative anaerobes. Qhov zoo tshaj plaws kub rau lawv txoj kev loj hlob yog 30-37 degrees. Lawv tsim xim av, liab, txiv kab ntxwv, qab zib los yog daj colony. Cov kab mob ntawm cov kab mob yog cov qws zoo li. Ib qho kawg yog nqaim, lwm qhov yog sib npaug. Cov duab ntawm qee lub hlwb yuav zoo li lub cocoon, yuav ceg los yog forked. Cov ntsiab lus nyob ib leeg, ua khub, nrog rau hauv cov saw luv. Cov kab mob Propionic acid muaj C15-saturated fatty acid ntawm daim nyias nyias lipids, menaquinones. Thaum fermentation, lawv tsim ib yam khoom tshwj xeeb. Nws yogpropionic acid. Nws, qhov tseeb, muab lub npe rau cov kab mob no. Cov genus Propionibacterium suav nrog peb pawg kab mob: Propionibacterium propionicus, dermal thiab classical.
yam ntxwv
Hom classic suav nrog cov kab mob propionic acid ntawm cheese thiab mis nyuj. Lawv suav nrog 4 hom: P. Acidipropionici, P. Jensenii, P. Thoenii thiab P. Freudenreichii. Cov kab mob ntawm daim tawv nqaij propionic acid nyob, feem, ntawm daim tawv nqaij ntawm tib neeg, nyob rau hauv lub rumen ntawm ntau yam ruminants. Lawv suav hais tias yog kev tiv thaiv kab mob lom thiab muaj txiaj ntsig microflora. Cov kab mob Propionic acid ntawm hom no muab cov tshuaj tiv thaiv immunostimulating, muaj txiaj ntsig zoo rau cov noog thiab tsiaj txhu. Hauv qhov no, lawv tau siv los ua cov khoom ntawm prophylactic thiab kho cov neeg ua haujlwm. Cov kab mob ntawm daim tawv nqaij tsis yog nyob ntawm qhov chaw noj qab haus huv xwb. Lawv pom nyob rau hauv pob txuv, tsis tshua muaj nyob rau hauv cov ntsiab lus ntawm lub plab, mos thiab purulent ntaub so ntswg abscesses, ntshav, qhov txhab. Txawm li cas los xij, lawv txoj kev koom tes hauv qhov tshwm sim ntawm cov kab mob tsis tau tsim muaj kev ntseeg siab. Cov kab mob thib peb suav nrog tsuas yog Propionibacterium proponicus. Lawv nyob hauv av.
Synthetic peev xwm
Lawv tau tsim txaus hauv cov kab mob propionic acid, tab sis txawv nyob ntawm hom thiab hom. Tam sim no nws tau tsim muaj qee cov kab mob muaj peev xwm kho cov molecular nitrogen, tsim cov vitamins ntawm lawv tus kheej (tshwj xeeb, B12), thiab siv hydrocarbons. Thaum fermentation, lawv tso biomass,uas yog dav siv nyob rau hauv kev xyaum. Tsis tas li ntawd, cov khoom ntawm lawv cov haujlwm yog acetic thiab propionic acids.
Enzymatically Inactive Biomass Applications
Synthesis khoom siv:
- Nyob hauv tsiaj txhu. Inactive biomass ua raws li ib tug protein ntawm ib tug unicellular kab mob. Qhov tseem ceeb tshwj xeeb yog sulfur-muaj cov amino acids, tshwj xeeb tshaj yog methionine, threonine thiab lysine, B-group vitamins, kab kawm. Lawv pom muaj ntau hauv cov biomass uas tsim los ntawm cov kab mob propionic acid.
- Kev npaj tsim los ntawm cov kab mob tua hluav taws kub muaj cov tshuaj tiv thaiv kab mob, tshuaj tua kab mob, tshuaj tiv thaiv kab mob. Tsis tas li ntawd, cov kev tshawb fawb tau pom tias P. acnes muaj peev xwm ua kom qeeb ntawm kev loj hlob ntawm ntau hom qog, nrog rau cov malignant.
- Killed P. granulosum ua raws li qhov chaw ntawm porphyrins. Nrog rau cov hlau complexes, lawv yog siv los ua pigments thiab dyes, nrog rau hauv kev lag luam khoom noj khoom haus, raws li catalysts rau redox cov tshuaj tiv thaiv, oxidation ntawm mercaptans nyob rau hauv cov roj thiab roj cov khoom, hydrocarbons, thiab lwm yam. Tsis tas li ntawd, P. granulosum yuav siv tau los tsim kho. thiab kev npaj kho mob.
YActive Biomass
Tam sim no, cov khoom lag luam uas zais cov kab mob propionic acid tau siv ntau yam. Sourdough, tshwj xeeb, yog ib qho ntawm cov khoom xyaw feem ntau hauv kev lag luam khoom noj. Piv txwv li, nws yog siv nyob rau hauvbakeries. Nrog rau cov kab mob lactic acid thiab cov poov xab, propionic acid microorganisms suav nrog hauv qee cov kab lis kev cai pib. Lawv muab kev nce hauv txee lub neej ntawm qhob cij. Qhov no yog ua tiav vim qhov inhibitory nyhuv ntawm propionic acid ntawm kev loj hlob ntawm pwm fungi. Tsis tas li ntawd, cov khoom yog enriched nrog vitamin B12. Qhov xwm txheej no tseem ceeb tshwj xeeb rau dieters thiab neeg tsis noj nqaij. Cov kab lis kev cai pib kuj yog siv rau ensiling fodder. Active biomass yog siv nyob rau hauv zus tau tej cov B12. Tsim cov vitamin los ntawm cov tshuaj synthesis yog tsis yooj yim sua hauv kev xyaum. Rau qhov no, cov kab mob propionic acid tau siv.
Agricultural applications
Thaum khaws cov qoob loo, cov kab tsuag tuaj yeem rhuav tshem txog li 15% ntawm tag nrho cov ntim. Thaum cov av noo ntau tshaj 14%, cov nplej sov thiab pib ua pwm. Txoj kev khaws cia uas suav nrog kev ziab, khaws cia ntawm qhov kub thiab txias lossis hauv cov thawv kaw yog qhov nyuaj heev rau kev siv hauv kev xyaum. Txhawm rau daws cov teeb meem no, hauv qee lub tebchaws tau txau cov nplej nrog cov tshuaj tsis muaj zog ntawm propionic acid. Nws txo cov kev loj hlob ntawm cov noob, neutralizes microorganisms, thiab feem ntau pwm fungi.
Propionic acid kab mob: "Evita"
Nyob rau hauv nruab nrab-90s ntawm lub xyoo pua xeem, ib pab pawg neeg ntawm domestic microbiologists tsim ib tug tshwj xeeb cov khoom. Nws muaj qhov tshwj xeeb tshaj plaws kho mob thiab prophylactic cov txiaj ntsig thiab muaj txiaj ntsig lom neeg. Cov khoom muaj npe "Evita". Thaum nwsnyuj cov kua mis yog siv nyob rau hauv ntau lawm. Kev tsim khoom yog ua raws li txoj kev fermentation siv lub cim tshwj xeeb, nthuav tawm raws li kev ruaj ntseg symbiosis ntawm kab lis kev cai, ntawm cov kab mob propionic acid ua lub luag haujlwm tseem ceeb.
Mechanism of action
cov kab mob Propionic acid suav tias muaj txiaj ntsig zoo rau lub cev. Nyob rau hauv cov hnyuv, lawv rov qab cov proteins tom qab kev ntxhov siab, raug rau cov tshuaj sib txuas, hluav taws xob ultraviolet. Cov kab mob tiv thaiv kev tsim cov tshuaj uas ua rau muaj kev loj hlob ntawm oncology. Nyob rau hauv lawv lub xub ntiag, lub plab hnyuv ib puag ncig yog hloov kho nyob rau hauv cov kev taw qhia ntawm txo pH. Cov kab mob muaj cov nyhuv antagonistic rau cov kab mob thiab cov kab mob pathogenic, txhawb kev loj hlob ntawm lacto- thiab bifidobacteria. Nws tau raug tsim los hais tias lawv muaj kev tiv thaiv siab rau cov tshuaj tua kab mob, tshwj xeeb tshaj yog cov pab pawg penicillin, nrog rau sulfonamides thiab nce acidity ntawm lub plab ib puag ncig. Tag nrho cov khoom tshwj xeeb ntawm cov kab mob ntawm cov kab mob propionic acid tsim lub hauv paus ntawm kev ua haujlwm ntawm Evita cov khoom. Ntxiv mus, nws yog suav hais tias tsuas yog cov tshuaj uas B12 muaj nyob rau hauv ib koob tshuaj. Cov vitamin no koom nrog hauv hematopoiesis, ua kom cov ntshav txhaws. Nws yog qhia rau malignant anemia, atherosclerosis, alcoholism, dystrophy, cerebral palsy, Down syndrome, anemia (hlau deficiency), ntau yam sclerosis, psoriasis, plab polyposis.
Y
Effect on casein (mis nyuj protein)
Lub ntsiab lus no tsis zoo nqus los ntawm tus neeg laus cov kab mob vim tsis muaj cov ntsiab lus uas ua rau nws tawg. Thaum cov mis nyuj fermented siv cov khoom Evita, cov protein yog decomposed tag rau hauv cov amino acids. Lawv tsim cov khoom noj nruab nrab rau cov plab hnyuv microflora. Nyob rau hauv tus txheej txheem ntawm fermentation, ntau volatile fatty acids kuj tsim. Ntawm lawv yog acetic, propionic, oily, folic, isovaleric, formic thiab lwm yam. Cov kua qaub no ua raws li qhov tseem ceeb ntawm kev noj haus rau lub plab hnyuv epithelium. Lawv kuj pab txhawb rau kev hloov pauv ntawm cov kua tsib acids hauv cov theem nrab thiab lawv cov reabsorption. Cov nyhuv no yog siv los kho cov mob raws plab nrog Evita hauv cov neeg mob uas muaj kab mob ntawm cov hnyuv thiab daim siab.
Extra
Nws yuav tsum tau muab sau tseg tias cov kab mob symbiosis xaiv los ntawm cov kws tshawb fawb yog qhov txawv los ntawm kev ua haujlwm siab ntawm cov khoom tiav rau kev ua ntawm phenol. Qhov no, nyob rau hauv lem, qhia txog kev khaws cia ntawm nws cov tshuaj zoo nyob rau hauv lub plab zom mov. Nyob rau hauv lub koom haum tshawb fawb ntawm Hygienic Regulation thiab Toxicology, Serpukhov, lub antimutagenic zog ntawm cov khoom kuj proven. Qhov tseem ceeb ntawm cov khoom yog nws lub peev xwm los kho cov microflora sai. Nws, ntawm qhov tod tes, ua kom lub cev txav mus los tawm tsam cov kab mob ntau txaus.
