Iintonga zehagu ebilisiweyo ekhenkcezisiweyo
| Intshayelelo yemveliso | Iimathiriyeli ekrwada zivela kwiindawo zokuxhela kunye namashishini okubhaliswa kwamanye amazwe e-China.Imathiriyeli ekrwada engenisiweyo ikakhulu ivela eFransi, eSpain, eNetherlands, njl. |
| iinkcukacha | Iinkcukacha ezingakumbi, yamkela isiko |
| Iimbonakalo | Umlinganiselo wamafutha ukuya kubhityile ngu-3:7, utyebile kodwa awunyuki. |
| Faka isitishi | Ilungele ukulungiswa kokutya, ikhonkco lokutyela kunye namanye amashishini. |
| Iimeko zokugcina | Ukugcinwa kweCryopreservation ngaphantsi -18℃ |
Inyama engumkhenkce ibhekisa kwinyama ebixheliwe, ikhe yapholiswa ngaphambili ukususa iasidi, ikhenkceziswe, ze igcinwe ngaphantsi kwe -18°C, kwaye ubushushu benyama enzulu bungaphantsi kwe -6°C.Inyama engumkhenkce ekumgangatho ophezulu ikholisa ukuba ngumkhenkce ku -28°C ukuya ku -40°C, kwaye umgangatho wenyama kunye nencasa yawo ayohlukanga kakhulu kwezo zenyama esandul' ukukhenkcezwa okanye ebandayo.
Ukuba iqhwa kwiqondo lokushisa eliphantsi, umgangatho kunye nencasa yenyama iya kuhluka kakhulu, yiyo loo nto abantu abaninzi becinga ukuba inyama ekhenkcezisiweyo ayimnandi.Nangona kunjalo, ezi ntlobo zimbini zenyama ekhenkcezisiweyo zinexesha elide, ngoko ke zisetyenziswa kakhulu.
Impembelelo yeMicrobial
1. Iintlobo ezahlukeneyo ze-biochemical reactions zinciphisa ngexesha le-metabolism ye-microbial substances kumaqondo aphantsi, ngoko ukukhula kunye nokuveliswa kwee-microorganisms ngokuthe ngcembe kuncipha.
2. Xa amaqondo obushushu ehla ngaphantsi kweqondo lomkhenkce, amanzi akwi-microorganisms kunye nendawo ejikelezileyo angumkhenkce, nto leyo eyandisa i-viscosity ye-cytoplasm, yandisa i-electrolyte concentration, itshintsha ixabiso le-pH kunye ne-colloidal state yeeseli, kwaye i-denatures iiseli.Ukulimala, olu tshintsho lwangaphakathi nangaphandle lwendalo luyimbangela echanekileyo yokuthintela okanye ukufa kwe-microbial metabolism.
Impembelelo yee-enzymes
Iqondo lokushisa eliphantsi aliyithinteli ngokupheleleyo i-enzyme, kwaye i-enzyme isenokugcina inxalenye yomsebenzi wayo, ngoko ke i-catalysis ayipheli, kodwa iqhubela phambili ngokucothayo.Ngokomzekelo, i-trypsin isene-reaction ebuthathaka kwi-30 ° C, kwaye i-lipolytic enzymes isenokubangela i-fat hydrolysis kwi-20 ° C.Ngokuqhelekileyo, umsebenzi we-enzyme unokuncitshiswa ube yincinci kwi-18 ° C.Ngoko ke, ukugcinwa kweqondo lokushisa eliphantsi kunokwandisa ixesha lokugcinwa kwenyama.
