Qhov sib txawv tseem ceeb ntawm cov kab mob endospores thiab fungal spores yog lub koom haum cellular ntawm ob hom spores. Cov kab mob endospores yog cov qauv dormant muaj nyob rau hauv cov kab mob prokaryotic. Fungal spores yog cov qauv tsim muaj nyob hauv eukaryotic fungi.
Cov kab mob endospores muaj nyob rau hauv cov kab mob hlwb, thiab lawv yog cov qauv dormant uas tuaj yeem muaj sia nyob rau qhov hnyav ib puag ncig. Yog li ntawd, cov endospores germinate thaum lub chaw tsim nyog tau ua tiav. Nyob rau hauv sib piv, fungal spores yog exospores uas tso tawm rau sab nrauv rau sporulation.
Cov kab mob endospores yog dab tsi?
Cov kab mob endospores yog prokaryotic nyob rau hauv cov xwm thiab tam sim no nyob rau hauv spore-forming kab mob xws li Bacillus, Clostridium, thiab lwm yam. Cov no yog dormant qauv nyob rau hauv cov kab mob uas muaj sia nyob heev hnyav ib puag ncig tej yam kev mob xws li kub hloov pauv, hluav taws xob thiab toxicity tej yam kev mob. Tag nrho cov txheej txheem ntawm kev tsim spore tshwm sim nyob rau hauv ntau theem.
Sporulation
Nws yog txheej txheem uas cov ntaub ntawv spore. Ib ob daim nyias nyias tsim ntawm qhov tawg ntawm DNA npog lub endospore. Cov membranes no ces synthesis peptidoglycan. Calcium dipicolinate kuj tseem suav nrog rau kev tsim cov forespore. Keratin zoo li cov protein ua lub tsho tiv no. Tom qab cov kab mob degradation, cov spores tawm. Kev cog qoob loo tsuas yog thaum cov xwm txheej tsim nyog.

Germination
Cov phab ntsa spore tawg thaum lub sij hawm germination, thiab cov ntaub ntawv tshiab vegetative cell. Kev tawg ntawm phab ntsa spores tshwm sim los ntawm kev siv lub cev, tshuaj lossis hluav taws xob. Qhov no vegetative cell yog ces muaj peev xwm ntawm kev loj hlob thiab kev loj hlob. Lub cell vegetative emerges raws li ib tug outgrowth ntawm lub endospore thaum lub sij hawm germination.
Cov kab mob fungal yog dab tsi?
Cov kab mob fungal yog los ntawm eukaryotic keeb kwm. Spores yog tam sim no raws li kev tsim cov qauv hauv cov kab mob fungi. Cov spores no yog exospores thiab nyob ntawm cov chav kawm sib txawv, cov exospores muaj ntau lub npe xws li Ascospores, Basidiospores, Zoospores, thiab lwm yam. Fungal spores yog microscopic thiab sib txawv ntawm qhov loj, duab, xim thiab hom kev tso tawm. Cov spores feem ntau disperse los ntawm huab cua los yog raws li cov tee dej. Qee qhov tso tawm thaum lub caij tshwj xeeb lossis thoob plaws xyoo.
Daim duab 02: Cov Kab Mob Kab Mob
Cov kab mob fungal yog qhov tseem ceeb hauv kev lag luam vim tias lawv tuaj yeem ua rau ntau tus kab mob fungal hauv cov nroj tsuag. Cov no suav nrog cov nroj tsuag kab mob xws li Botrytis cinerea thiab Cochliobolus heterotrophus. Qee cov fungal spores ua raws li daim tawv nqaij ua xua.
Dab tsi zoo sib xws ntawm cov kab mob endospores thiab fungal Spores?
- Ob leeg yog cov qauv siv tshuab.
- Ob Kab Kab Mob Endospores thiab Fungal Spores muaj peev xwm tsim tawm thiab loj hlob.
Dab tsi yog qhov txawv ntawm Bacterial Endospores thiab Fungal Spores?
YBacterial Endospores vs Fungal Spores |

| Cov kab mob endospores yog cov qauv dormant muaj nyob rau hauv cov kab mob prokaryotic. | Fungal spores yog cov qauv tsim muaj nyob hauv eukaryotic fungi. |
| Hom Spore | |
| Endospore originates sab hauv. | Cov kab mob fungal tshwm sim rau sab nraud. Li no, lawv yog exospores. |
| qauv | |
| Endospore muaj cov qauv tuab nrog lub tsho loj. | Cov kab mob fungal muaj ntau qhov loj, cov duab thiab xim. |
| Muaj Dipocolinate | |
| Dipocolinate muaj nyob rau hauv endospores. | Dipocolinate tsis muaj nyob hauv cov kab mob fungal. |
| Heat Resistance | |
| Nyob rau hauv endospores, tshav kub tsis kam yog siab. | Heat resistance is Low in fungal spores. |
| Tshuaj thiab hluav taws xob tiv thaiv | |
| Endospores tiv taus tshuaj thiab hluav taws xob. | Cov kab mob fungal tsis tshua muaj tshuaj lom neeg thiab hluav taws xob. |
| Piv txwv | |
| Bacillus, Clostridium, thiab lwm yam tsim cov endospores. | Aspergillus, Penicillium, pwm, poov xab, tsim cov kab mob fungal. |
Summary – Kab mob Endospores vs Fungal Spores
Cov kab mob endospores thiab fungal spores yog ob lub qauv tshwj xeeb koom nrog hauv kev yug me nyuam thiab kev loj hlob ntawm cov kab mob thiab cov fungi feem. Cov kab mob endospores muaj nyob hauv cov qauv tsim. Thaum cov kab mob raug mob hnyav, ib lub cell ntawm cov kab mob degrades, tab sis endospore ciaj sia. Thaum lub germination tej yam kev mob zoo, lub vegetative hlwb tsim tom qab sporulation. Nyob rau hauv sib piv, fungal spores yog exospores uas muaj peev xwm undergo reproduction thaum lawv tso tawm rau ib puag ncig. Qhov no yog qhov txawv ntawm cov kab mob endospores thiab fungal spores.
