Cov iodine reacts nrog cov hmoov nplej rau tsim ib qho xim av tsaus. Yog li, hydrolysis ntawm hmoov nplej yuav tsim kom muaj thaj chaw ntshiab nyob ib puag ncig kab mob kev loj hlob. Bacillus subtilis yog qhov zoo rau hmoov txhuv nplej siab hydrolysis (daim duab hauv qab no ntawm sab laug).

Tom qab ntawd, vim li cas cov kab mob hydrolyze starch?

Cov hmoov txhuv nplej siab molecules yog loj dhau mus nkag rau hauv kab mob cell, so ib co kab mob tso tawm exoenzymes kom degrade hmoov nplej nyob rau hauv subunits uas ua tau tom qab ntawd siv los ntawm lub cev. Clearing ib ncig ntawm lub kab mob kev loj hlob qhia tias lub cev muaj hydrolyzed hmoov txhuv nplej siab . Iodine tau ntxiv rau qhov no hmoov nplej agar phaj.

Tom qab ntawd, lo lus nug yog, puas yog E coli starch hydrolysis zoo? Hauv kev ua qauv qhia no, kev ua ntawm ob hom kab mob, Bacillus subtilis thiab Escherichia coli , yog piv rau hmoov nplej agar. Qhov no yog ib tsis zoo tshuaj tiv thaiv rau cov hmoov txhuv nplej siab hydrolysis xeem. Lub B. subtilis tsim ib thaj tsam meej nyob ib ncig ntawm kev loj hlob uas yog a zoo tshuaj tiv thaiv (Fig.

Cov kab mob twg ua rau cov hmoov txhuv nplej siab?

Ib tsev neeg ntawm kab mob hu ua Ruminococcaceae proliferates nyob rau hauv txoj hnyuv thaum muaj ntau ntawm cov salivary enzyme - hu ua amylase - muaj. Cov kab mob paub txog tawg tiv taus hmoov nplej yog li nws yuav zom tau, ib yam dab tsi tib neeg amylase ua tsis tau.

Puas yog Bacillus subtilis hydrolyze starch?

Cov hmoov txhuv nplej siab agar yog qhov sib txawv nruab nrab uas ntsuas lub peev xwm ntawm lub cev los tsim cov exoenzymes, suav nrog a-amylase thiab oligo-1, 6-glucosidase, uas hydrolyze hmoov txhuv nplej siab . Thaj tsam ntawm clearing ib puag ncig Bacillus megaterium thiab Bacillus subtilis qhia tias ob leeg muaj peev xwm hydrolyze hmoov txhuv nplej siab.
