Txoj kev khaws cia Chlorella feem ntau suav nrog cov hauv qab no:
- Cryoppreservation
Chlorella yog hom algae nyob. Tom qab kev tsim khoom, nws yuav tsum tau khaws cia ntawm qhov kub qis ntawm 0℃thiab 4℃kom ntseeg tau tias kev ruaj ntseg ntawm cov kab mob. Tsis txhob khov, vim tias khov yuav ua rau cov phab ntsa ntawm tes tawg, o, thiab necrotize. Hauv qhov ntsuas kub no, Chlorella tuaj yeem khaws cia li ntawm peb lub hlis. Txhawm rau khaws cia, tshem cov Chlorella ntawm lub tub yees thiab muab tso rau hauv lub thoob loj kom sov nws li qub. Thaum nws tau mus txog qhov kub thiab txias, ncuav nws mus rau hauv dej thiab ntxiv kab lis kev cai nruab nrab rau aeration thiab ua kom muaj zog. Nws tuaj yeem siv tom qab kwv yees li 24 teev.
- Frozen Cia
Tom qab centrifuging Chlorella, tshem tawm cov supernatant thiab khaws cov precipitate.
Ntxiv ib qho kev khaws cia, xws li 20% glycerol lossis 10% ethylene glycol tov, rau cov dej nag los tiv thaiv Chlorella hlwb.
Sib tov cov Chlorella thiab khaws cia tsis huv thiab hloov mus rau ib qho cryovial.
Khaws lub cryovial nyob rau hauv ib tug -80℃lub freezer rau tsawg kawg ob peb lub hlis. Thaw thiab hloov mus rau kab lis kev cai nruab nrab rau kev rov qab ua ntej siv. Nqus Freeze-Drying
Chlorella yog khov sai sai ntawm ib ncig ntawm -70 degree, ces nqus tsev vacuum- kom qhuav kom tshem tawm tag nrho cov dej noo. Txoj kev no tso cai rau kev khaws cia ntev ntawm chlorella.
