Vim tias muaj cov phab ntsa ntawm tes tawv, cov kab mob ua kom muaj qhov tseeb, txawm tias lawv txawv raws li cov duab, qhov loj thiab cov qauv. Thaum saib nyob rau hauv lub teeb tsom iav, feem ntau cov kab mob tshwm sim nyob rau hauv variations ntawm peb loj duab: tus pas nrig ( bacilus ), lub sphere ( coccus ) thiab cov kauv hom (vibrio).
Raws li txoj cai, peb hom kab mob sib txawv yog dab tsi?
Muaj peb pib cov duab ntawm kab mob : coccus, bacillus, thiab kauv. Raws li cov dav hlau ntawm kev faib, lub coccus puab tuaj yeem tshwm sim hauv ob peb txawv Kev npaj: diplococcus, streptococcus, tetrad, sarcina, thiab staphylococcus. Cov bacillus puab tuaj yeem tshwm sim li ib tus kab mob bacillus, streptobacillus, lossis coccobacillus.
Tom qab ntawd, lo lus nug yog, qhov txawv ntawm morphology thiab kev npaj ntawm cov kab mob yog dab tsi? Morphology . Microbiologists kuj tuaj yeem txheeb xyuas kab mob los ntawm lawv cov colony morphology , los yog cov tsos thiab cov yam ntxwv ntawm lub kab mob thaj chaw. Thaum kev npaj hais txog cov pab pawg ntawm cov tib neeg lub hlwb, morphology piav txog cov tsos ntawm cov pab pawg ntawm kab mob , los yog colonies.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi stains siv los qhia cov morphology thiab kev npaj ntawm cov kab mob hlwb?
Ntshav liab stain (crystal violet) yog siv rau stain tus kab mob ua ntej, cov xim kab mob yog decolorized thiab ces stained nrog ib tug liab stain (Safranin). Kab mob nrog tuab cell phab ntsa khaws thawj (ntsuab) stain thiab hu ua Gram positive.
Koj puas tuaj yeem txiav txim siab cov kab mob ntawm tes los ntawm nws lub npe?
Thawj puab hu ua coccus, plural cocci. Cells ntawd muaj cocci puab yog spherical, zoo li cov pob me me. Nws yog ib qho tseem ceeb kom nco ntsoov uas lub sij hawm 'bacillus' ua tau piav txog cell zoo li zoo li kab mob nyob rau hauv lub genus Bacillus. Qhov thib peb kab mob zoo li yog kauv.

Koj tuaj yeem pom cov kab cab kab mob nyob qhov twg?
HABITAT. Beard worms nyob rau hauv dej hiav txwv pem teb ntawm continental slopes thiab hauv dej hiav txwv trenches. Qee hom tsuas yog pom nyob rau ntawm cov ntoo lwj ze ntawm lub hiav txwv tob tob ntawm qhov tob ntawm 328 txog 32,808 ko taw (100 txog 10,000 meters). Cov dej hiav txwv tob no hu ua hydrothermal vents
Cov tshuaj tua kab mob twg thaiv cov kab mob protein ntau?
Tetracyclins yog ib hom tshuaj tua kab mob uas suav nrog cov thawj tetracycline nrog rau doxycycline thiab minocycline. Cov tshuaj tua kab mob no khi rau A qhov chaw ntawm 30s ribosome, tiv thaiv tRNA los ntawm kev nqa cov amino acids tshiab. Yog tias tRNA tsis tuaj yeem txuas mus rau ribosome, ces tsis muaj cov proteins tshiab tuaj yeem ua tau
Cov kab mob twg muaj cov kab mob eukaryotic?
Cov kab mob thiab Archaea tsuas yog prokaryotes. Cov kab mob uas muaj eukaryotic hlwb hu ua eukaryotes. Tsiaj txhu, nroj tsuag, fungi, thiab protists yog eukaryotes. Tag nrho cov kab mob multicellular yog eukaryotes
Yuav ua li cas cov kab mob tuaj yeem raug mob los ntawm cov ntsev ntau ntawm txoj kev?
Raws li kev soj ntsuam koj tau ua hauv qhov kev ua haujlwm hauv chav kuaj no, piav qhia seb cov kab mob tuaj yeem raug mob li cas los ntawm cov ntsev ntau ntawm txoj kev. Cov kab mob tuaj yeem raug mob vim tias cov dej ntsev yuav ua rau cov dej tsis zoo los ntawm cov kab mob lossis cov nroj tsuag ntawm txoj kev; Lub cev qhuav dej tuaj yeem ua rau puas lossis tua cov hlwb
Vim li cas cov kab mob Gram tsis zoo tshwm liab liab thaum cov kab mob Gram zoo pom ntshav liab?
Gram zoo hlwb stain ntshav vim lawv cov peptotidoglycan txheej yog tuab txaus, txhais tau tias tag nrho cov kab mob Gram zoo yuav khaws lawv cov stain. Gram tsis zoo hlwb stain liab vim lawv muaj ib tug nyias peptidoglycan phab ntsa, thiab lawv yuav tsis khaws ib yam ntawm cov ntshav stain los ntawm crystal violet
