Abstract Objective

Kawm txog kev tua cov kab mob aerosol microorganism los ntawm pulse electric field (PEF) thiab nws cov txheej txheem.

Cov txheej txheem

Raws li "cov tshuaj tua kab mob hauv huab cua ntawm kev soj ntsuam kev soj ntsuam" hauv qhov thib ob tsab ntawm "kev tshuaj xyuas tshuaj tua kab mob
thiab cov txheej txheem kev normalization"(2002), qhov kev hloov kho thiab kev sim teb tau siv los ntsuas kev tuaeffect of PEB.Flow cytometric method tau siv rau kev tsom xam ntawm huab cua los ntawm PI / TO nrog ob npaug stains.

Cov txiaj ntsig

Tom qab Pulse hluav taws xob teb cua tua kab mob ua haujlwm rau 120 min, qhov nruab nrab tua tus nqi ntawm B.subtilis var. nigerhauv chav aerosolyog 99.16% ntawm qhov kub ntawm 23-24 ℃ thiab 64% ~ 74% hauv cov av noo.Thaum pulse hluav taws xobCov tshuaj tua kab mob hauv huab cua tau khiav 8 teev txhua hnub ntawm cov cua kub ceev uas cov txheej txheem txuas ntxiv mus rau 180 d, tus nqi ntawm cov kab mob tua tau ntau dua 90% ntawm 1st, 7th, 14th, 30th, 60th, 90th hnub.Cov txiaj ntsig ntawm FCM tau pom tias muaj qhov nce ntxivpermeability thiab DNA degradation ntawm Staphylococcus albus hom thaum lub aerosol raug rau 20 min los ntawm PEF.

Cov thev naus laus zis tseem ceeb ntawm pulse electric field (PEF) tau tsim hauv peb AP600ta cua tua kab mob hom purifier.

Thaum cov pa phem nkag mus rau hauv lub hauv paus PEF tivthaiv ntawm cov cua sterilizer purifier, lub ultra energetc ions generated los ntawm ultra energetcpulses nyob rau hauv cov ntsiab lus tseem ceeb cuam tshuam rau cov molecular bonds ntawm cov pa phem, ua rau CC thiab CH bonds uas tsim.cov molecular bonds ntawm feem ntau cov kab mob phem thiab gases tawg, yog li cov teeb meem microorganisms raug tua raws li lawvDNA raug rhuav tshem thiab cov pa phem xws li Formaldehyde (HCHO) thiab Benzene (C6H6) tau tawg rau hauv CO2 thiabH2O.Lub tshuab cua purifier no tau raug kuaj los ntawm lub chaw kuaj mob uas nws cov kab mob tua tau zoo yog 99.9%.
