subtilis tseem feem ntau suav hais tias yog ib lub luag haujlwm aerob , ob peb txoj kev tshawb fawb tsis ntev los no tau ua pov thawj tias tus kab mob no yog qhov tseeb facultative anaerob , uas muaj peev xwm ntawm ob qho tib si fermentation thiab anaerobic Ua pa nrog nitrate lossis nitrite siv los ua lub davhlau ya nyob twg electron txais (19, 20).
Ua raws li qhov xav tau, puas Bacillus subtilis xav tau oxygen?
Bacillus subtilis kab mob muaj tau txiav txim siab nruj aerobic, txhais tau tias lawv xav tau oxygen loj hlob thiab lawv tsis tuaj yeem raug fermentation. Txawm li cas los xij, cov kev tshawb fawb tsis ntev los no qhia tau tias lawv tuaj yeem loj hlob hauv cov xwm txheej anaerobic ua rau lawv facultative aerobes.
Qhov thib ob, yog B subtilis yog mannitol fermenter? Thaum lub Bacillus subtilis raug cais tawm ntawm Mannitol Ntsev Agar phaj, xim ntawm lub phaj kuj hloov ntawm liab mus rau daj. Bacillus subtilis tsis muaj peev xwm ferment mannitol thiab tseem lub Mannitol xeem tau txais txiaj ntsig zoo.
Tom qab ntawd, ib tug kuj yuav nug, yog B subtilis ib tug facultative anaerobe?
Bacillus subtilis , tseem hu ua hay bacilus los yog nyom bacilus , yog Gram-positive, catalase-positive kab mob, pom nyob rau hauv cov av thiab lub plab zom mov ntawm ruminants thiab tib neeg. B . subtilis tau keeb kwm tau muab cais ua ib lub luag haujlwm aerobe, txawm tias muaj pov thawj tias nws yog ib qho facultative anaerobe.
Bacillus subtilis zoo rau dab tsi?
Probiotics muaj cov antioxidant tsim B . subtilis tau tsim cov txiaj ntsig zoo hauv kev tshawb fawb txog cem quav thiab kab mob H. pylori. Lawv kuj tseem yuav pab txhawb lub cev tiv thaiv kab mob, lub siab ua haujlwm, thiab kho hniav.

Puas yog Phosphorus yog hlau lossis tsis yog hlau?
Phosphorus yog cov hlau tsis muaj hlau uas nyob hauv qab nitrogen hauv pawg 15 ntawm lub sijhawm. Cov khoom no muaj nyob rau hauv ntau hom, uas yog dawb thiab liab yog qhov zoo tshaj plaws paub. Dawb phosphorus yog twv yuav raug hu ntau exciting ntawm ob
Puas yog beryllium yog hlau lossis nonmetal lossis metalloid?
Beryllium yog hlau. Nws yog nyob rau hauv alkaline ntiaj teb hlau pawg nyob rau hauv lub periodic lub rooj thiab muaj tshuaj thiab lub cev muaj zog zoo ib yam li cov magnesium thiab txhuas, tab sis muaj ib tug ntau dua melting point tshaj ob qho tib si
Puas yog S epidermidis aerobic lossis anaerobic?
Aureus feem ntau yog hemolytic ntawm cov ntshav agar; S. epidermidis tsis yog hemolytic. Staphylococci yog facultative anaerobes uas loj hlob los ntawm kev ua pa aerobic los yog los ntawm fermentation uas yields feem ntau lactic acid. Cov kab mob no yog catalase-positive thiab oxidase-negative
Puas yog carbon hlau lossis nonmetal lossis metalloid?
Carbon muaj 4 electrons nyob rau hauv nws lub valence plhaub uas ua rau nws ib tug metalloid tab sis feem ntau nws yog suav hais tias yog tsis yog hlau
Puas yog malleable hlau lossis nonmetal lossis metalloid?
Hlau, Metalloids, thiab Nonmetals. Cov ntsiab lus tuaj yeem faib ua hlau, nonmetals, lossis metalloids. Cov hlau yog cov khoom siv hluav taws xob zoo ntawm cov cua sov thiab hluav taws xob, thiab tuaj yeem ua tau zoo (lawv tuaj yeem muab hammered rau hauv cov ntawv) thiab ductile (lawv tuaj yeem kos rau hauv cov hlau). Cov metalloids yog nruab nrab hauv lawv cov khoom
