Ngokusho kocwaningo lwamuva olushicilelwe kumagazini i-“Exploring Food”, ithimba lamazwe ngamazwe elivela kwa-Israyeli, e-Iceland, eDenmark nase-Austria lisebenzise ubuchwepheshe be-biotechnology obuthuthukisiwe ukuhlakulela i-spirulina equkethe i-vitamin B12 esebenzayo, elingana nokuqukethwe kwenyama yenkomo. Lona umbiko wokuqala wokuthi i-spirulina iqukethe i-vitamin B12 esebenzayo.
Ucwaningo olusha kulindeleke ukuthi lubhekane nokuntuleka kwezakhamzimba okuvame kakhulu. Abantu abangaphezu kwezigidi eziyi-1 emhlabeni wonke bahlushwa ukuntuleka kwe-B12, futhi ukuthembela enyameni nasemikhiqizo yobisi ukuthola i-B12 eyanele (ama-microgram angu-2.4 ngosuku) kuyinselele enkulu emvelweni.
Ososayensi baphakamise ukusebenzisa i-spirulina esikhundleni senyama nemikhiqizo yobisi, okuyinto ehlala isikhathi eside. Kodwa-ke, i-spirulina yendabuko iqukethe uhlobo abantu abangenakulusebenzisa ngokwezinto eziphilayo, oluvimbela ukwenzeka kwalo esikhundleni salo.
Ithimba lisungule uhlelo lwe-biotechnology olusebenzisa ukuphathwa kwe-photon (izimo zokukhanya ezithuthukisiwe) ukuthuthukisa ukukhiqizwa kwe-vitamin B12 esebenzayo ku-spirulina, ngenkathi futhi ikhiqiza amanye amakhemikhali asebenzayo ane-antioxidant, anti-inflammatory, kanye nemisebenzi yokuthuthukisa amasosha omzimba. Le ndlela entsha ingakhiqiza i-biomass ecebile ngezakhamzimba ngenkathi ifinyelela ukungathathi hlangothi kwe-carbon. Okuqukethwe kwe-vitamin B12 esebenzayo ekukhuleni okuhlanziwe kungama-microgram angu-1.64/100 amagremu, kanti enyameni yenkomo kungama-microgram angu-0.7-1.5/100 amagremu.
Imiphumela ikhombisa ukuthi ukulawula i-photosynthesis ye-spirulina ngokukhanya kungakhiqiza izinga elidingekayo le-vitamin B12 esebenzayo emzimbeni womuntu, okuhlinzeka ngenye indlela eqhubekayo yokudla okungokwesiko okususelwa ezilwaneni.
