Ngokocwaningo lwakamuva olushicilelwe kujenali ethi “Exploring Food”, ithimba lamazwe ngamazwe lase-Israel, e-Iceland, e-Denmark nase-Austria lasebenzisa i-biotechnology ethuthukisiwe ukutshala i-spirulina equkethe i-bioactive vitamin B12, elingana nokuqukethwe nenyama yenkomo. Lona umbiko wokuqala wokuthi i-spirulina iqukethe i-bioactive vitamin B12.
Ucwaningo olusha kulindeleke ukuthi lubhekane nokushoda kwe-micronutrient okuvamile. Abantu abangaphezu kwebhiliyoni elilodwa emhlabeni wonke bahlushwa ukushoda kwe-B12, futhi ukuthembela enyameni nemikhiqizo yobisi ukuze bathole i-B12 eyanele (ama-microgram angu-2.4 ngosuku) kubangela inselele enkulu emvelweni.
Ososayensi bahlongoze ukusebenzisa i-spirulina esikhundleni senyama nemikhiqizo yobisi, esimeme kakhudlwana. Kodwa-ke, i-spirulina yendabuko iqukethe uhlobo abantu abangakwazi ukulisebenzisa ngokwebhayoloji, okuvimbela ukuba nokwenzeka kwalo esikhundleni.
Ithimba lenze uhlelo lwe-biotechnology olusebenzisa ukuphathwa kwe-photon (izimo zokukhanyisa ezithuthukisiwe) ukuze kuthuthukiswe ukukhiqizwa kwe-vitamin B12 esebenzayo ku-spirulina, kuyilapho futhi ikhiqiza ezinye izinhlanganisela ze-bioactive ezine-antioxidant, anti-inflammatory, kanye nemisebenzi yokuthuthukisa amasosha omzimba. Le ndlela entsha ingakhiqiza i-biomass enomsoco ngenkathi ifinyelela ukungathathi hlangothi kwe-carbon. Okuqukethwe kwe-bioactive vitamin B12 emasikweni ahlanziwe yi-1.64 micrograms / 100 amagremu, kanti enyameni yi-0.7-1.5 micrograms / 100 amagremu.
Imiphumela ikhombisa ukuthi ukulawula i-photosynthesis ye-spirulina ngokukhanya kungaveza izinga elidingekayo likavithamini B12 osebenzayo womzimba womuntu, okuhlinzeka ngenye indlela esimeme ekudleni kwendabuko okutholakala ezilwaneni.
