Izingulube zemvelo zinezici zokuphepha, ukungabi nobuthi, ukungenwa kwe-carcinogenicity kanye ne-biodegradation. Ama-microorganisms asatshalaliswa kabanzi futhi anezinhlobonhlobo ezinkulu. Ngakho-ke, ukudaya kwe-microbial kunethuba elibanzi lokufaka isiceloizindwanguimboni.
1.I-Microbial pigment
I-Microbial pigment iyi-metabolite yesibili ye-microorganisms, enemibala eminingi, ebomvu, ewolintshi, ephuzi, eluhlaza, e-cyan, ensomi, emnyama nensundu, njll. Imibala ye-Microbial ingahlukaniswa zibe izinhlobo ezimbili, njengezingulube ezincibilikayo emanzini nezingezona- izingulube ezincibilikayo emanzini. Uma kuqhathaniswa nabanye odayi bemvelo, odayi be-microbial banesikhathi esifushane sokukhiqiza kanye nezindleko eziphansi, okulula ukukhiqizwa kwezimboni.
Kunezindlela ezimbili eziyinhloko zokukhiqiza ama-microbial pigments, njengama-secretions avela ekukhuleni kwama-microorganisms kanye ne-pigments ekhiqizwa ukuguqulwa kwengxenye eyodwa ye-culture medium njenge-substrate. Kwesesibili, idinga ukwengeza izinto ezithile ezidingekayo ekukhiqizweni kwe-pigment endaweni yesiko ukuze kuthuthukiswe ukukhiqizwa kombala kanye nokwandisa isivuno sombala.
2.Izindlela zokudaya nge-microbial
KhiphaUkudaya
Kuwukusebenzisa ama-microorganisms aphakathi kwe-liquid ukuze abenze bakhiqize ama-pigment amaningi, bese bethola isisombululo se-pigment ngokuhlukanisa, ukukhipha kanye nokugxila.
Isixazululo se-pigment singasetshenziswa ngokuqondile njengotshwala obudayi, kodwa futhi singenziwa sibe yimpushana ye-pigment bese sisetshenziswa. Ukudaya okukhishiwe kunobubanzi bokusebenza futhi kulula ukwenza izimboni. Kodwa inenqubo yokukhipha eyinkimbinkimbi, enezindleko eziphezulu.
Ukudaya Amaseli Amagciwane
Ukudaya kwamangqamuzana amagciwane kuhlukaniswe ngezindlela ezimbili kuye ngendawo yesiko. Enye i-liquid fermentation medium. Lapho ama-microorganisms enza isamba esikhulu sombala, oyinyumbaindwanguingafakwa kwikhambi lamasiko ukuze kube nokudaya kwesiko. Enye i-agar medium eqinile. Ngemuva kwesikhathi sokutshala, lapho ama-microorganisms ehlanganisa inani elikhulu lezingulube, amangqamuzana e-bacterial kanye ne-medium yengezwa amanzi futhi abiliswe, futhi indwangu idaywe ku-80 ℃.
Ukudaya kwamangqamuzana amagciwane kulula, okonga isikhathi namandla futhi kulula ukukuphatha. Kodwa akufanelekile kuma-microorganisms akhiqiza ama-pigment angancibiliki.
Odayi bemvelo beMicrobial bavumelana nemvelo futhi banobuchwepheshe obuvuthiwe bokuvutshelwa kanye nokuhambisana okuhle kwe-biocompatibility. Ziya ngokuya zithandwa phakathi kwabantu. Izindwangu ezidaywe ngodayi abancane zinemibala eyingqayizivele nokucwebezela. Odayi bemvelo abancane abancane banamathuba amahle okusebenza.
