Lwm yam kab mob catalase-zoo muaj xws li Listeria, Corynebacterium diphtheriae, Burkholderia cepacia, Nocardia, tsev neeg. Enterobacteriaceae (Citrobacter, E. coli, Enterobacter, Klebsiella, Shigella, Yersinia, Proteus, Salmonella, Serratia), Pseudomonas , Mycobacterium tuberculosis, Aspergillus, Cryptococcus, thiab
Hais txog qhov no, cov kab mob dab tsi muaj catalase?
Cov kab mob catalases suav nrog cov pab pawg ntau tshaj plaws hauv Eubacteria, Archaeabacteria, Protista, Fungi, Plantae, thiab Animalia, whereas catalase -peroxidases tsis pom nyob rau hauv cov nroj tsuag thiab tsiaj txhu thiab nthuav tawm ob qho tib si catalatic thiab peroxidatic kev ua ub no.
Tsis tas li ntawd, catalase zoo txhais li cas? Cov catalase xeem xeem rau lub xub ntiag ntawm catalase , ib qho enzyme uas zom cov khoom tsis zoo hydrogen peroxide rau hauv dej thiab oxygen. Cov npuas yog a zoo tshwm sim rau lub xub ntiag ntawm catalase . Yog tias tsis muaj npuas, nws yog qhov tshwm sim tsis zoo; qhov no qhia tias lub cev ua tsis tsim catalase.
Puas yog bacillus catalase zoo lossis tsis zoo?
Catalase test yog siv los sib txawv aerotolerant hom Clostridium, uas yog catalase tsis zoo, los ntawm Bacillus hom , uas yog qhov zoo.
Puas yog Streptococcus mutans catalase zoo?
Cov txheej txheem tseem ceeb rau kev sib txawv ntawm Staphylococcus thiab Streptococcus genera yog kev kuaj catalase . Staphylococci yog catalase zoo hos Streptococci yog Catalase tsis zoo. Catalase yog ib qho enzyme siv los ntawm cov kab mob los ntxias cov tshuaj tiv thaiv ntawm kev txo cov hydrogen peroxide rau hauv dej thiab oxygen.

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
Cov kab mob thiab cov kab mob ua haujlwm zoo li cas?
Ob leeg cov kab mob thiab cov kab mob muaj cov phab ntsa ntawm tes (txawm hais tias sib txawv hauv cov qauv thiab muaj pes tsawg leeg) Feem ntau cov kab mob thiab cov kab mob tau txais lub zog los ntawm kev ua pa aerobic (ua pa hauv cov kab mob me ntsis txawv dua li hauv Eukaryotes tab sis cov pa oxygen ib txwm xav tau rau oxidise suab thaj, hauv dej kawg. thiab carbon dioxide yog tsim)
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
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
