Iav Petri Dishes: Ib qho tseem ceeb ntau yam hauv chav kuaj
Raws li cov cuab yeej classic hauv chav kuaj, lub khob Petri tais tau ntev tau txais txiaj ntsig zoo rau nws cov khoom tshwj xeeb thiab ntau yam kev siv. Hauv qab no, peb yuav tshawb xyuas kom meej txog ntau yam kev siv iav Petri tais diav.
Microbial Culture thiab Observation
Iav Petri tais diav yog ib qho cuab yeej tseem ceeb hauv kev tshawb fawb microbiological. Cov kws tshawb fawb tuaj yeem tsim cov kab mob uas tsim los rau kab lis kev cai mus rau qhov nruab nrab loj hlob uas muaj cov khoom noj tshwj xeeb, thiab tom qab ntawd siv lub khob Petri tais los pab txhawb lawv txoj kev loj hlob. Ua tsaug rau kev ruaj ntseg tshuaj zoo heev thiab qhov muag pom ntawm iav, qhov kev loj hlob thiab kev hloov morphological ntawm cov kab mob tuaj yeem pom meej meej, muab lub hauv paus tseem ceeb rau lawv cov kev sib cais, kev txheeb xyuas, thiab kev faib tawm.
Cell Culture thiab Observation
Ntxiv nrog rau kab lis kev cai microbial, iav Petri tais kuj tau siv dav rau kev coj noj coj ua ntawm tes thiab kev soj ntsuam. Hauv kev tshawb fawb ntawm tes biology, cov kws tshawb fawb yuav tsum tau inoculate cell mus rau qhov nruab nrab ntawm kev loj hlob uas muaj cov kev loj hlob tshwj xeeb thiab tom qab ntawd cog rau hauv qhov tsim nyog ib puag ncig. Lub tiaj tus- qauv tsim hauv qab ntawm iav Petri phaj ua kom ntseeg tau tias cov hlwb raug faib sib npaug thoob plaws hauv qab, yog li ua kom yooj yim rau kev soj ntsuam thiab cov ntaub ntawv ntawm lawv txoj kev loj hlob. Tsis tas li ntawd, iav Petri cov tais diav tuaj yeem ua ke nrog ntau yam fluorescent dyes thiab cov txheej txheem sau npe los soj ntsuam kev faib tawm thiab kev hloov pauv ntawm intracellular biomolecules, xws li cov protein thiab nucleic acids.
Kev Tshuaj Ntsuam Xyuas Tshuaj thiab Kev Ntsuam Xyuas Toxicity
Glass Petri cov tais diav kuj ua lub luag haujlwm tseem ceeb hauv cov txheej txheem kev tsim tshuaj. Cov kws tshawb fawb tuaj yeem qhia cov tshuaj rau hauv cov tais diav no los soj ntsuam lawv cov teebmeem ntawm ntau yam kev coj cwj pwm lom neeg ntawm cov hlwb- xws li kev loj hlob, kev loj hlob, thiab kev sib txawv. Los ntawm kev sib piv cov txiaj ntsig ntawm cov tshuaj sib txawv ntawm cov hlwb, cov tshuaj muaj peev xwm sib tw nrog kev kho mob tuaj yeem raug tshuaj xyuas thiab txheeb xyuas. Concurrently, iav Petri cov tais diav tuaj yeem siv los ntsuas tshuaj toxicity los ntawm kev saib xyuas qhov cuam tshuam ntawm cov tshuaj ntawm cellular morphology, qauv, thiab kev ua haujlwm, yog li muab cov ntaub ntawv tseem ceeb rau kev tshawb fawb tshuaj thiab kev tsim kho.
Lwm Daim Ntawv Thov
Ntxiv rau cov ntawv thov tseem ceeb uas tau hais los saum toj no, iav Petri cov tais diav pom muaj txiaj ntsig hauv ntau qhov chaw, suav nrog cov kab lis kev cai cog qoob loo, kab kab, thiab kev saib xyuas ib puag ncig. Lawv qhov tshwj xeeb tshuaj lom neeg ruaj khov thiab lub teeb xa hluav taws xob ua rau lawv muaj kev cia siab dav rau daim ntawv thov hauv ntau hom no.
Iav Petri cov tais diav yog nyiam heev rau lawv cov khoom tshwj xeeb thiab ntau yam kev siv. Hauv qhov chaw kuaj mob, lawv ua haujlwm tsis yog tsuas yog cov cuab yeej tseem ceeb rau kev tshawb fawb hauv kev qhuab qhia xws li microbiology thiab cell biology tab sis kuj tseem yog cov cuab yeej tseem ceeb hauv thaj chaw xws li kev txhim kho tshuaj mus rau kev saib xyuas ib puag ncig.
