Qhov sib txawv tseem ceeb ntawm Bacillus thiab Clostridium yog Bacillus yog ib hom kab mob gram-zoo uas loj hlob hauv cov kab mob aerobic, tsim oblong endospores thiab secretes catalase thaum Clostridium yog ib hom kab mob gram-zoo uas loj hlob nyob rau hauv cov mob anaerobic., tsim lub raj mis zoo li endospores thiab tsis zais catalase.
Clostridium thiab Bacillus yog ob lub noob qoob loo ntawm phylum Firmicutes. Lawv yog cov kab mob gram-positive endospore-forming kab mob. Ntxiv mus, lawv yog cov kab mob zoo li tus kab mob. Txawm hais tias lawv nyob hauv tib lub cev, lawv cov chav kawm, kev txiav txim thiab tsev neeg txawv. Kuj tseem muaj qhov sib txawv ntawm Bacillus thiab Clostridium raws li cov duab ntawm endospore, aerobic thiab anaerobic tej yam kev mob, thiab kev tso tawm ntawm catalase enzyme. Bacillus spp yog cov kab mob aerobic thaum Clostridium spp yog cov kab mob anaerobic. Yog li ntawd, Bacillus spp vam meej nyob rau hauv lub xub ntiag ntawm oxygen, thaum Clostridium spp vam meej nyob rau hauv tsis muaj oxygen.
Bacillus yog dab tsi?
Bacillus yog ib hom kab mob phylum Firmicutes. Lawv nyob hauv chav kawm Bacilli, xaj Bacillales thiab tsev neeg Bacillaceae. Lawv yog cov kab mob aerobic uas yog gram-zoo thiab tus pas nrig. Muaj ntau tshaj 266 hom Bacillus paub hauv cov genus no. Bacillus hom tsim oval-shaped endospores. Vim cov endospores no, Bacillus hom tuaj yeem nyob twj ywm rau ntau xyoo. Bacillus hom degrade organic teeb meem hauv av.
Daim duab 01: Bacillus
Qee hom kab mob Bacillus yog cov kab mob. B. cereus ua rau zaub mov lom, thaum B. anthracis ua rau anthrax. Qee hom Bacillus muaj txiaj ntsig zoo hauv kev ua liaj ua teb, tshwj xeeb tshaj yog B. thuringiensis thiab B. sphaericus yog siv los ua tshuaj tua kab.
Clostridium yog dab tsi?
Clostridium yog ib hom kab mob anaerobic. Lawv yog cov phylum Firmicutes. Ntxiv mus, lawv nyob rau hauv chav kawm Clostridia, txiav txim Clostridiales ntawm tsev neeg Clostridiaceae. Lawv yog cov kab mob gram-zoo, pas nrig-zoo li tus kab mob uas muaj fermentative thiab endospore-forming. Clostridium tsim lub raj mis zoo li endospores. Lawv tsis zais catalase. Muaj nyob ib ncig ntawm 250 hom Clostridium. Lawv tuaj yeem nyob dawb lossis kab mob.
Daim duab 02: Clostridium
Clostridium botulinum (khoom noj khoom haus tsis zoo (tshwj xeeb yog cov zaub mov kaus poom); botulism), Clostridium perfringens (gas gangrene), Clostridium tetani (tetanus) thiab Clostridium sordellii yog plaub hom Clostridium uas ua rau tib neeg muaj kab mob. Qee hom Clostridium muaj txiaj ntsig zoo hauv kev lag luam. C. acetobutylicum yog siv los tsim butanol.
Dab tsi zoo sib xws ntawm Bacillus thiab Clostridium?
- Bacillus thiab Clostridium yog ob hom ntawm tus pas nrig, feem ntau yog kab mob gram-zoo.
- Lawv yog cov kab mob ua kab mob.
- Lawv yog cov tswv cuab ntawm phylum Firmicutes.
- Bacillus thiab Clostridium feem ntau piav raws li Gram-variable.
- Muaj kab mob hauv ob hom.
- Qee hom Bacillus thiab Clostridium ua rau zaub mov lom.
- Tsis tas li ntawd, qee hom ntawm ob hom tsim muaj co toxins.
Qhov txawv ntawm Bacillus thiab Clostridium yog dab tsi?
Bacillus yog ib hom kab mob aerobic, uas tsim oblong endospores thiab secretes catalase, thaum Clostridium yog ib hom kab mob anaerobic, uas ua rau lub raj mis zoo li endospores. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm Bacillus thiab Clostridium. Tsis tas li ntawd, Bacillus hom muaj nyob rau hauv chav kawm Bacilli, xaj Bacillales, thiab tsev neeg Bacillaceae, thaum Clostridium hom yog nyob rau hauv chav kawm Clostridia, xaj Clostridiales, thiab tsev neeg Clostridiaceae.
Ntxiv mus, lwm qhov sib txawv ntawm Bacillus thiab Clostridium yog Bacillus hom secrete catalase, thaum Clostridium hom tsis zais catalase. Tsis tas li ntawd, Bacillus tsim oblong endospores, thaum Clostridium tsim lub raj mis zoo li endospores. Qhov no kuj yog qhov sib txawv tseem ceeb ntawm Bacillus thiab Clostridium. Tsis tas li ntawd, Food poisoning thiab anthrax yog ib co kab mob uas tshwm sim los ntawm Bacillus thaum botulism, gas gangrene thiab tetanus yog tshwm sim los ntawm Clostridium.
Summary – Bacillus vs Clostridium
Bacillus thiab Clostridium yog ob hom kab mob ntawm phylum Firmicutes. Lawv yog cov kab mob gram-positive endospore-forming kab mob. Bacillus hom yog cov kab mob aerobic uas tsim oval-shaped endospores. Ntxiv mus, lawv secrete catalase. Hauv qhov sib piv, Clostridium hom yog cov kab mob anaerobic uas tsim lub raj mis zoo li endospores. Lawv tsis zais catalase. Ob lub genera suav nrog cov kab mob uas ua rau cov zaub mov lom thiab lwm yam kab mob ntawm tib neeg. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm Bacillus thiab Clostridium.
