TCBS yog tsis yog autoclaved vim hais tias: Cov xov xwm no muaj Ox bile (Oxgall), ib tug derivative ntawm cov kua tsib ntsev uas inhibit gram-zoo kab mob tej zaum yuav rhiab heev thaum autoclaving . Qhov no agar yuav tsum tau boiled thiab tsis yog autoclaved kom tsis txhob caramelization (browning) ntawm sucrose.
Kuj paub, vim li cas peb thiaj li autoclave media?
Los ntawm autoclaving , tag nrho cov kab mob yog tua kom txhua yam uas loj tuaj yog cov kab mob koj npaj siab loj hlob. Autoclaving kuj pab homogenize xov xwm (vim qhov kub thiab txias) txij li solubility hauv dej nce ntawm qhov kub siab dua.
Vim li cas kab lis kev cai xov xwm sterilized ua ntej siv? Media rau cov kab mob loj hlob thiab cov hlwb yog sterilized ua ntej siv los tiv thaiv kev kis kab mob ntawm qhov xav tau kab lis kev cai nrog rau lwm hom kab mob los yog hlwb. Lub xub ntiag ntawm cov hlwb tsis xav tau rau kab lis kev cai media tuaj yeem ua rau qhov tsis ua haujlwm kab lis kev cai los yog cuam tshuam cov txiaj ntsig ntawm kev sim yav tom ntej.
Kuj paub yog, dab tsi loj hlob ntawm TCBS?
TSO Agar yog siv rau kev xaiv cais ntawm tus kab mob cholera vibrios thiab Vibrio parahaemolyticus los ntawm ntau qhov chaw kho mob thiab tsis muaj tshuaj kho mob. Tag nrho cov kab mob Vibrio spp., tshwj tsis yog Vibrio hollisae, yuav loj hlob ntawm TCBS Agar.
Lub ntsiab lus ntawm Tcbs yog dab tsi?
Thiosulfate-citrate-bile ntsev-sucrose agar, los yog TCBS agar, yog ib hom kev xaiv agar kab lis kev cai phaj uas yog siv nyob rau hauv microbiology chaw soj nstuam cais Vibrio hom. TCBS agar yog xaiv heev rau kev cais ntawm V. cholerae thiab V. parahaemolyticus nrog rau lwm hom Vibrio.

Recharge yog infiltration ntawm dej mus rau hauv ib qho subsurface tsim, feem ntau los ntawm infiltration ntawm nag los yog daus meltwater los ntawm qhov chaw
Lub hauv paus ntsiab lus twg piav qhia tias vim li cas AFC poob qis thaum cov zis nce ntxiv cov ntsiab lus piav qhia vim li cas AVC nce ntxiv thaum cov zis nce ntxiv?
AFC poob qis vim qhov tso zis ntau ntxiv vim muaj kev sib kis. Tus nqi ruaj khov yog kis mus rau ntau dua thiab ntau dua units ntawm cov khoom tso tawm raws li cov zis ntau ntxiv. AVC nce raws li cov zis nce vim qhov txo qis rov qab los. Vim qhov txo qis rov qab mus rau kev ua haujlwm, nws raug nqi ntau dua los tsim txhua chav ntxiv ntawm cov zis
Dab tsi yog autoclaved aerated qhob blocks?
Autoclaved aerated qhob (AAC) yog alightweight, precast, ua npuas ncauj ua vaj tse khoom tsim nyog rau kev tsim pob zeb masonry unit (CMU) likeblocks. Ua los ntawm quartz xuab zeb, calcined gypsum, txiv qaub, cement, dej thiab txhuas hmoov, AAC khoom yog kho nyob rau hauv tshav kub thiab siab nyob rau hauv ib tug autoclave
Yuav ua li cas yog autoclaved aerated qhob ua?
Autoclaved aerated qhob (AAC) yog tsim nrog cov khoom sib xyaw zoo, cov cement, thiab tus neeg sawv cev nthuav tawm uas ua rau cov khoom sib xyaw tshiab kom sawv zoo li khob cij. Qhov tseeb, hom pob zeb no muaj 80 feem pua ntawm huab cua. Nyob rau hauv lub Hoobkas qhov twg nws yog tsim, cov khoom yog molded thiab txiav mus rau hauv precisely dimensioned units
