Khoom noj khoom haus Agar yog lub hom phiaj dav dav, khoom noj khoom haus nruab nrab siv rau kev cog qoob loo ntawm microbes txhawb kev loj hlob ntawm ntau yam ntawm cov kab mob uas tsis yoo mov. Khoom noj khoom haus agar yog nrov vim tias nws tuaj yeem loj hlob ntau hom kab mob thiab kab mob, thiab muaj ntau cov as -ham xav tau rau kev loj hlob ntawm cov kab mob.
Ib yam li ntawd, nws tau nug, koj yuav npaj agar media li cas?
Kev Npaj Cov Khoom Noj Agar
- Dissolve qhov nruab nrab lub cev qhuav dej hauv qhov tsim nyog ntim ntawm cov dej ntxhia xws li, 23 gm lub cev qhuav dej cov as -ham agar (saib cov chaw tsim khoom qhia) hauv 1000 ml dej distilled.
- Tshav kub nrog nquag nquag thiab rhaub rau 1 feeb kom yaj cov hmoov kom tiav.
Ib yam li ntawd, vim li cas cov dej distilled siv los npaj cov kab lis kev cai? Dej distilled yog nyiam nyob rau hauv siv , uas yog vim kais dej dej tej zaum yuav muaj calcium thiab magnesium ntsev uas tuaj yeem hnov mob nrog phosphate pom nyob rau hauv peptone los yog nqaij nyug extract thiab tsim calcium phosphate thiab magnesium phosphate ntsev uas yog dej insoluble uas tuaj yeem tiv thaiv kev loj hlob ntawm cov kab mob me me.
Ntawm no, vim li cas peptones thiab agar siv hauv kev npaj tawm?
Nws yog tsim los ntawm kev zom cov protein ib nrab xws li nqaij, gelatin thiab casein siv cov kua qaub lossis enzymes. Lub hom phiaj ntawm peptone hauv cov as -ham agar nruab nrab yog los muab thawj qhov chaw ntawm cov organic nitrogen rau kev loj hlob ntawm kab mob microbial, thiab nws kuj tseem tuaj yeem yog cov khoom siv carbohydrates thiab cov vitamins.
Vim li cas agar siv los cog cov kab mob?
Agar feem ntau siv hauv chav kuaj mob kom pab pub mis thiab loj hlob kab mob thiab lwm yam kab mob. Nws ua raws li kab lis kev cai uas muab cov as -ham thiab qhov chaw rau cov khoom no rau loj hlob , tab sis vim nws tsis txaus rau cov kab mob me me, lawv tsis tuaj yeem noj thiab rhuav tshem nws.

Vim li cas cov ntawv xov xwm tawv tawv siv los ntsuas kev txav mus los?
Kev txav mus los ntawm cov kab mob tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev muaj sia ntawm cov kab mob nrog rau muaj peev xwm ua rau muaj kab mob. Mobility Agar yog ib nrab khoom nruab nrab uas nthuav tawm txoj kev loj hlob, thiab tso cai rau cov kab mob txav mus los ntawm qhov nruab nrab
Dab tsi yog qhov zoo ntawm kev siv agar li Agglutinant hauv kab lis kev cai xov xwm?
Agar. Bacteriological agar yog siv los ua tus neeg sawv cev gelling hauv kev npaj ntawm kev tshaj tawm kab lis kev cai nrog rau hauv kev loj hlob thiab hauv vitro nthuav tawm ntawm cov ntaub so ntswg cog. Qhov txiaj ntsig tseem ceeb ntawm agar no yog qhov tsis muaj cov tshuaj uas tuaj yeem npog qhov pom kev loj hlob ntawm cov kab mob me me
Qhov feem pua ntawm agar yog nyob rau hauv cov khoom siv xov xwm?
Khoom nruab nrab muaj agar ntawm ib qho concentration ntawm 1.5-2.0% los yog lwm yam, feem ntau inert solidifying tus neeg sawv cev
Txoj kev tshaj xov xwm loj hauv kev kawm txog kev noj qab haus huv yog dab tsi?
Cov xov xwm loj ua lub luag haujlwm tseem ceeb hauv kev tshaj tawm cov ntaub ntawv kho mob thiab ua kom muaj kev paub txog kev kawm txog kev noj qab haus huv. Media tsis tsuas yog nthuav tawm kev paub, tab sis kuj qhia thiab qhia tib neeg nyob rau lub sijhawm. Qhov no thaum kawg pab hloov tus cwj pwm & tus cwj pwm ntawm cov neeg tuaj saib kom ua tiav kev noj qab haus huv zoo dua
Kev tshaj xov xwm cuam tshuam txog kev sib deev li cas?
Rau peb txoj kev paub, qhov no yog thawj txoj kev tshawb fawb los tshawb xyuas kev sib raug zoo hauv kev sib raug zoo thiab kev sib daj sib deev thiab kev cuam tshuam ntawm kev saib xyuas niam txiv. Yog li, cov uas nquag siv hauv kev tshaj xov xwm tuaj yeem koom nrog hauv kev coj tus kheej uas muaj kev pheej hmoo ntau vim tias muaj cov phooj ywg sib koom tes ntau dua uas cuam tshuam rau lawv cov kev xav thiab kev coj noj coj ua hauv zej zog
