Daim ntawv thov ntawm Ultrasound hauv kev cog ntoo
Feem ntau ntawm cov khoom siv tshuaj ntsuab ntawm cov nroj tsuag ntuj yog cov khoom lag luam tawm, thiab nws yog feem ntau tsim nyog yuav tsum tawg lub hlwb thaum rho tawm. Cov kev siv tshuab lossis tshuaj tua hluav taws uas nyob hauv ib qho nyuaj qee zaus nyuaj kom ua tiav qhov tawg zoo tshaj plaws. Ultrasound tau qhia hauv kev rho tawm ntawm cov khoom siv tshuaj ntsuab los ntawm cov nroj tsuag muaj av thiab dej hiav txwv. Tawm ntawm cov txiaj ntsig pom tseeb.
Daim ntawv thov ntawm Ultrasound hauv kev cog ntoo
Cov av hauv av: Daim ntawv thov ntawm ultrasound rau biotechnology yog qhov chaw tshiab rau kev tshawb fawb. Cov kev tshawb fawb pom tau tias ultrasound tuaj yeem ua kom lub zog ntawm lub cev thiab cov biochemical uas qee cov enzymes thiab cov hlwb koom nrog. Los ntawm kev hloov pauv loj ntawm cov tshuab reactant, cov kev ua ntawm enzymes tuaj yeem ua kom zoo dua qub thiab cov txheej txheem ntawm metabolic ntawm cov hlwb tuaj yeem ua kom nrawm dua. Ultrasound yog siv rau qhov tsis zoo ntawm cov hmoov txhuv nplej siab, tuaj yeem txhim kho qhov solubility ntawm cov hmoov txhuv nplej hauv cov dej thaum khaws cov yam ntxwv ntawm cov hmoov txhuv nplej siab pom tseeb, tab sis cov enzyme kev ua haujlwm tau txo qis tom qab rov ua ultrasonic kev kho mob; Ultrasound yog siv rau degrade chitin nrog kev kub ceev, tus nqi qis, thiab cov ntsiab lus tsis hloov ntawm cov amino acid; Ultrasonic siv los mus rho tawm cov kab mob fungal polysaccharides, xws li cordyceps polysaccharide, lentinan, hericium polysaccharide, thiab lwm yam. Piv nrog rau kev siv thev naus laus zis, txoj kev ultrasonic enzymatic muaj ntau dua qhov tseem ceeb npaum li cas, tsis muaj cov khoom siv ploj thiab tshwm sim thaum lub sijhawm cov tshuaj tiv thaiv; ntxiv rau, ultrasonic kuj tseem siv los ua degrade thiab rho tawm ntau cov txiv hmuv Glycan thiab lwm yam. Ganoderma lucidum polysaccharide yog ib hom kab mob lignified fungal polysaccharide. Lub xovtooj ntawm tes muaj protein, chitin, cellulose thiab lignin. Nws cov qauv yog compact. Nws yog qhov nyuaj rau kev rhuav tshem phab ntsa ntawm tes los ntawm txoj kev kho kom dav, thiab nws yog qhov nyuaj rau rho tawm cov khoom xyaw zoo. Tus kwv tij crystallinity raug txo los ntawm 23.4 rau 0 los ntawm qhov kev nqis tes ntawm 120 W ultrasonic yoj, thaj tsam ntawm thaj chaw tau nce li ntawm 85.5%, thiab qhov ntsuas qhov hydrolysis tau nce siab.
Tam sim no, qee qhov kev tshawb nrhiav tau tshawb fawb txog kev siv ultrasound los siv tshuaj muaj txiaj ntsig zoo los ntawm cov nroj tsuag hauv av. Qhov kev tshawb nrhiav ntawm kev rho tawm ntawm anthraquinones los ntawm rhubarb los ntawm ultrasound qhia tau hais tias tag nrho kev rho tawm tuaj yeem ncav cuag 95.25% tom qab kho ultrasonic rau 10 feeb, thaum lub sijhawm rho tawm tag nrho tsuas yog 63.27% tom qab kho rau 3 teev; tus nqi rho tawm tuaj yeem mus txog 20 feeb tom qab ultrasonic rho tawm. 99.82%; daim ntawv chromatography thiab HPLC tau siv los tshuaj xyuas cov khoom siv tau los ntawm ob txoj hauv kev, uas pom tias kev kho ultrasonic tsis muaj kev cuam tshuam rau tus qauv ntawm cov khoom. Thaum kawm txog kev rho tawm ntawm berberine los ntawm rhizomes ntawm Coptis, lub sijhawm kho ultrasonic, ultrasonic zaus thiab sulfuric acid concentration tau tshawb xyuas. Cov txiaj ntsig pom tau tias qhov ua kom rho tawm ntawm 20 kHz ultrasonic rho tawm rau 30 min yog tib yam li ntawd ntawm kev xau rau 24 h (8.12%). Qhov kev kawm txog cov khoom rho tawm los ntawm nuclear sib nqus resonance spectrometer qhia tau hais tias ultrasonic tsis muaj kev cuam tshuam rau cov qauv ntawm berberine. Kev rho tawm ntawm rutin los ntawm Sophora sophora los ntawm ultrasonic vuag ntawm txawv zaus yog muab piv nrog kub alkali rho tawm-acid nag lossis daus. Tus txheej txheem ultrasonic tsis xav tau kev kho cua sov, thiab tsuas yog xav tau kev kho mob ultrasonic nrog zaus ntawm 20 kHz rau 30 min. Tus rho tawm tuaj yeem tau nce ntxiv ntawm 47.6%. Ultrasound yog siv nyob rau hauv cov txheej txheem ntawm cov tshuaj ntxuav tes uas sib xyaw ua kom sib xyaw ua kom zoo li muab rho tawm ntawm berberine los ntawm Coptis chinensis. Qhov rho tawm tus nqi ntawm berberine tau los ntawm ultrasonic extraction rau 30 feeb yog ntau dua 50% siab dua li ntawm alkaline so rau 24 teev. Lub Xeev Tshawb Fawb ntawm Biochemical Engineering ntawm Lub Tsev Kawm Txuj Ci thiab Kev Ua Lag Luam ntawm Kev Tshawb Fawb ntawm Suav Academy ntawm Kev Tshawb Fawb ua tiav lub teb chaws" qhov project tseem ceeb" Cog ntawm tes sau qoob loj thiab kev tsim khoom ntawm artemisinin", siv ultrasound los siv ntxiv ua kom muaj zog ntawm cov artemisinin nrog roj av ether, uas ua rau kom cov chaw rho tawm ntau ntxiv. Lub sijhawm rho tawm yog luv heev, txo cov kev daws teeb meem, thiab cov khoom siv rho tawm yog kuaj los ntawm ultraviolet spectrophotometry thiab HPLC txuj ci, uas qhia tau tias cov ntsiab lus tsis huv kuj tseem tsawg dua.
Algae Marine: Dunaliella salina yog nplua nuj hauv β-carotene. Thawj qhov xwm txheej rau kev rho tawm β-carotene los ntawm ntsev yog txhawm rau cov ntsev algae kom β-carotene tuaj yeem nkag mus sai thiab muaj txiaj ntsig nkag mus rau hauv nruab nrab nruab nrab xws li cov kua aqueous. Txij li thaum cov khoom rho tawm feem ntau yog cov tshuaj txuam nrog, lub hlwb feem ntau yuav tsum tau tawg thaum cov txheej txheem rho tawm. Vim tias cov tshuaj lom neeg muaj tshwm sim hauv cov txheej txheem, kev siv cov txheej txheem tshuaj lom neeg tuaj yeem yooj yim ua rau muaj kev hloov pauv hauv cov qauv thiab cov yam ntxwv ntawm cov khoom siv tawm thiab plam nws cov haujlwm, thiab nws tsis yooj yim rau kev tawg lub hlwb nrog cov neeg kho tshuab rhuav. Lu Deming li al. siv cov ultrasonic tsis muaj zog ntawm 30 kHz, 150 V, 46 kHz, 105 V, 4.64 kHz, 107 V, 48.2 kHz, thiab 109 V txhawm rau txhuam cov ntsev ua kom qis dua nyob rau qhov xwm txheej ntawm 20 ℃. Kev ua tiav ntawm tus lej algae tuaj yeem ncav cuag 87%. Phycobilisomes yog cov tshuaj tua hluav taws uas pom muaj qee yam algae. Cov khoom nyob rau sab nraum zoov ntawm phycobilisomes tsis yog qhia lawv muaj pes tsawg leeg thiab cov qauv yam ntxwv, tab sis kuj tseem cuam tshuam qhov sib txawv thiab kev hloov pauv ntawm algae hom. Txhawm rau kawm txog cov xim phycobilisomes, cov phycobilisome yuav tsum tau txais. Thaum lub zog algae lub cev tsis tuaj yeem tau los ntawm dracocystis siv cov tshuaj lom neeg thiab kev siv tshuab, txoj kev ua tiav phycobilisomes tuaj yeem tau txais los ntawm kev kho mob ultrasonic nrog zaus ntawm 20-50 kHz thiab qhov hluav taws xob 60 V rau 10 feeb. Lub hom phiaj ntawm ultrasound yog txhawm rau cov hlwb ntawm Asparagus solanacearum, ua rau pom lub plab hnyuv ntxig sab hauv, thiab tom qab ntawd tshee phycobilisome los ntawm daim nyias nyias ntawm cov tshuaj ntsiav sab hauv.
Tam sim no, qhov kev tshem tawm ntawm seaweed polysaccharides feem ntau adopts kev npau npau thiab ethanol nag lossis daus, thiab tus nqi rov qab yog tsawg heev. Lub National Key Laboratory ntawm Biochemical Engineering, Lub Tsev Kawm Txuj Ci thiab Hlau, Suav Academy ntawm Kev Tshawb Fawb, tab tom tshawb fawb Tub Rog" 863" Cov Nyiaj Pab Cov Hluas Kev Sib Tham" Ultrasonic leaching ntawm seaweed polysaccharides thiab kev tshawb fawb ntawm cov pa roj ua ntu rho tawm thiab sib cais kev ua" ;. Nyob rau tib lub sijhawm, nws yuav kawm thiab daws qhov teeb meem kev tsim tawm tshuab hauv kev siv ultrasound, nrog rau kev nthuav dav rau daim ntawv thov ntawm ultrasound hauv kev nthuav tawm ntawm cov khoom hauv hiav txwv.
Daim ntawv thov ntawm ultrasound hauv kev rho tawm ntawm cov khoom xyaw ntuj ntawm cov nroj tsuag av thiab cov nroj tsuag algae marine tau pom qhov pom tseeb thiab tau maj mam ua tib neeg' s mloog. Txawm hais tias qee qhov kev tshawb fawb tau ua nyob rau tam sim no, lawv txhua tus tau ua rau kev ntsuas me me hauv chav kuaj, thiab cov txheej txheem yooj yim cov kev sim tau coj tawm rau qee yam tshwj xeeb cov khoom siv rho tawm.
Thaum ultrasound siv los mus rho tawm cov khoom cog ntawm cov nroj tsuag, cov kev ua haujlwm ntawm kev nqis tes ua yuav tsum tau kawm hauv qhov tob txhawm rau txhawm rau tsim kev teeb tsa ntawm cov qauv dav dav ntxiv los muab lub hauv paus rau kev ua haujlwm ntawm cov khoom siv sib txawv. Nyob rau tib lub sijhawm, nws mob siab rau kev tshawb fawb txog teeb meem yam xws li tshuab thiab daws cov teeb meem ntawm ultrasonic extraction engineering amplification.
