Endospores pab kom cov kab mob pw tsaug zog rau lub sijhawm ntev, txawm ntau pua xyoo. Feem ntau hom kab mob tsis tuaj yeem hloov mus rau qhov endospores daim ntawv. Piv txwv ntawm cov kab mob genera uas tuaj yeem tsim endospores suav nrog Bacillus cereus, Bacillus anthracis, Bacillus Thuringiensis, Clostridium botulinum, thiab Clostridium tetani.

Ntawm no, puas yog Bacillus subtilis Endospore?

Bacillus subtilis yog kab mob Gram-positive, qwj-zoo li tus thiab catalase-zoo. Raws li nrog rau lwm cov tswv cuab ntawm genus Bacillus , nws tuaj yeem tsim ib qho endospores , kom ciaj sia ib puag ncig huab cua kub thiab desiccation.

Tsis tas li ntawd, tuberculosis puas yog Endospore? Lub genus Mycobacterium, uas yog tus tswv cuab ntawm pawg G + C siab ntawm cov kab mob Gram-zoo, suav nrog cov kab mob tseem ceeb, xws li M. tuberculosis thiab M. bovis bacillus Calmette-Guérin tsim ib hom spore hu ua endospores , uas tau pom tsuas yog nyob rau hauv qis G + C pawg ntawm Gram-zoo kab mob.

Raws li txoj cai, vim li cas Bacillus sp tsim Endospore?

9.4 ib. Physiological adaptation nyob rau hauv lub endospores ntau lawm yog ib tug tseem ceeb heev ciaj sia taus yam ntxwv ntawm ib co Gram-zoo rods xws li hom ntawm Bacillus thiab Clostridium. Endospore kev tsim yog feem ntau tshwm sim los ntawm qhov tsis muaj cov as-ham; nws yog ib tug stripped-down, dormant daim ntawv uas cov kab mob tuaj yeem txo nws tus kheej.

Cov kab mob endospores yog dab tsi?

Ib endospores yog ib qho dormant, tawv, tsis muaj kev sib deev qauv tsim los ntawm ib tug me me ntawm kab mob los ntawm tsev neeg Firmicute. Lub luag haujlwm tseem ceeb ntawm feem ntau endospores yog los xyuas kom muaj sia nyob ntawm a kab mob los ntawm lub sij hawm ntawm ib puag ncig kev nyuaj siab.
