Qhov Tseem Ceeb Qhov txawv - Kab mob vs Fungal Colonies
Cov yam ntxwv morphological tseem ceeb heev thaum ua tus cwj pwm ntawm cov kab mob thiab cov kab mob. Colony morphology yog ib txoj hauv kev zoo uas feem ntau siv los ntawm cov kws tshawb fawb los txheeb xyuas thiab piav qhia lawv. Cov yam ntxwv ntawm cov kab mob ntawm cov kab mob thiab cov kab mob fungal yog ua tib zoo saib thiab siv thaum cov kev tshawb fawb no. Cov kab mob loj hlob sai ntawm cov khoom noj uas muaj kab lis kev cai tshaj tawm piv rau cov kab mob fungi. Ntau hom kab mob thiab fungi tsim phenotypically sib txawv saib colony. Cov kab mob sib txawv ntawm qhov loj me, cov duab, kev ntxhib los mos, xim, cov npoo, thiab lwm yam. Yuav kom kawm txog cov kab mob colony morphology, cov kab mob thiab cov kab mob yuav tsum tau cog rau ntawm agar hauv Petri daim hlau los ntawm kev muab tag nrho cov khoom tsim nyog thiab cov xwm txheej. Cov kab mob loj hlob li me me oily dots ntawm agar media. Cov fungi loj hlob raws li powdery mats thoob plaws lub phaj agar. Qhov sib txawv tseem ceeb ntawm cov kab mob thiab cov kab mob fungal yog cov kab mob kab mob yog pom cov kab mob loj ntawm cov kab mob uas tshwm sim los ntawm cov kab mob ib leeg thaum cov kab mob fungal pom cov kab mob tshwm sim los ntawm ib qho kab mob los yog cov kab mob mycelial.
Dab tsi yog kab mob kab mob?
Cov kab mob yog cov kab mob me me uas tuaj yeem pom tsuas yog hauv qab lub tshuab tsom. Lawv yog cov kab mob unicellular prokaryotic. Lawv tsis tuaj yeem pom los ntawm peb qhov muag liab qab. Txawm li cas los xij, lawv pom thaum lawv loj hlob hauv cov cheeb tsam ntawm agar media hauv Petri daim phiaj. Cov kab mob colony tuaj yeem txhais tau tias yog qhov pom ntawm cov kab mob loj hlob ntawm cov khoom nruab nrab agar. Nws tau xav tias ib tus kab mob colony tshwm sim los ntawm ib lub xov tooj ntawm cov kab mob thiab tau muab faib ua binary fission rau ntau cov kab mob. Ib cheeb tsam muaj ntau lab ntawm cov kab mob genetic zoo tib yam kab mob. Yog li ntawd, ib tug kab mob colony raug coj los ua ib chav nyob rau hauv enumeration ntawm cov kab mob.

Cov kab mob kab mob tshwm sim ntawm agar media li cov dots me me. Cov cheeb tsam no qhia cov yam ntxwv sib txawv uas tseem ceeb heev hauv kev sib txawv thiab kev txheeb xyuas cov kab mob. Cov yam ntxwv colony sib txawv. Cov kab mob kab mob sib txawv hauv cov cheeb tsam loj, cov duab, xim, kev ntxhib los mos, nce, cov npoo, qhov pom ntawm qhov chaw, opacity, thiab lwm yam.
Cov kab mob fungal yog dab tsi?
Fungi yog ib pawg ntawm cov kab mob eukaryotic uas suav nrog cov kab mob xws li cov poov xab, filamentous fungi, thiab nceb. Fungi loj hlob zoo nyob rau hauv moist thiab sov. Lawv tuaj yeem raug cais raws li lawv cov morphological thiab molecular yam ntxwv. Cov yam ntxwv morphological tuaj yeem pom tau yooj yim los ntawm cov kab mob loj hlob ntawm cov khoom siv xws li qos yaj ywm dextrose agar (PDA). PDA yog qhov nruab nrab siv los cog cov kab mob uas feem ntau hauv cov chaw sim. Thaum fungi loj hlob ntawm cov khoom siv xov xwm, lawv loj hlob raws li thaj chaw. Fungal colony morphologies yog txawv ntawm ntau hom fungi. Cov yam ntxwv xws li pigmentation, kev ntxhib los mos thiab lwm yam tuaj yeem kawm los ntawm cov kab mob fungal.
Daim duab 02: Ascomycetes Fungal Colonies
Fungi colonies txawv ntawm cov kab mob kab mob. Fungi tshwm raws li powdery los yog fuzzy textured colonies. Hyphae ntawm fungi khiav thoob plaws hauv cov khoom tsim tawm rhizoid lossis filamentous colony. Cov kab mob fungal yuav tsis tshwm sim li me me oily dots. Mycelium thiab spore xim kuj txawv heev ntawm cov kab mob fungal.
Dab tsi yog qhov txawv ntawm kab mob thiab cov kab mob fungal?

| Cov kab mob kab mob yog cov pom cov kab mob ntawm cov kab mob ntawm cov khoom siv xov xwm. | Fungal colonies yog cov pom pawg ntawm fungi ntawm cov khoom siv xov xwm. |
| Nkauj tawm tshiab | |
| Cov kab mob kab mob tshwm sim li me me thiab creamy dots ntawm agar nto. | Fungal colonies tshwm li hmoov los yog filamentous pwm ntawm agar nto. |

| Cov kab mob kab mob loj hlob sai ntawm agar media. | Fungal colonies loj hlob sib piv qeeb ntawm agar media. |
| Cov kab mob kab mob tsis kis mus thoob qhov chaw. Lawv nyob twj ywm li cov dots ncig. | Cov kab mob fungal kis thoob plaws agar nto ib txwm. |
Summary – Kab mob vs Fungal Colonies
Ib pawg neeg tuaj yeem txhais tau tias yog qhov pom ntawm cov kab mob. Txhua lub colony pib los ntawm ib leeg niam cell. Yog li ntawd, cov cell nyob rau hauv ib tug colony yog genetic zoo tib yam. Cov kab mob thiab cov fungi loj hlob raws li cov cheeb tsam ntawm cov khoom siv xov xwm. Cov kab mob kab mob tshwm sim li me me creamy dots ntawm agar nto. Cov kab mob fungal tshwm sim li pwm ntawm qhov chaw agar. Qhov no yog qhov sib txawv tseem ceeb ntawm cov kab mob thiab cov kab mob fungal. Colony morphologies muaj txiaj ntsig zoo hauv kev txheeb xyuas thiab sib txawv ntawm cov kab mob thiab cov kab mob fungal.
