Malinga ndi kafukufuku waposachedwa wofalitsidwa mu magazini ya "Exploring Food", gulu lapadziko lonse lapansi lochokera ku Israel, Iceland, Denmark, ndi Austria linagwiritsa ntchito ukadaulo wapamwamba wa zamoyo kuti lipange spirulina yokhala ndi vitamini B12 yogwira ntchito, yomwe ili yofanana ndi ya ng'ombe. Ili ndi lipoti loyamba loti spirulina ili ndi vitamini B12 yogwira ntchito.
Kafukufuku watsopano akuyembekezeka kuthana ndi vuto limodzi mwa kusowa kwa michere yambiri m'thupi. Anthu opitilira 1 biliyoni padziko lonse lapansi ali ndi vuto la kusowa kwa vitamini B12, ndipo kudalira nyama ndi mkaka kuti apeze vitamini B12 yokwanira (2.4 micrograms patsiku) kumabweretsa vuto lalikulu pa chilengedwe.
Asayansi apereka lingaliro logwiritsa ntchito spirulina m'malo mwa nyama ndi mkaka, zomwe zimakhala zokhazikika. Komabe, spirulina yachikhalidwe ili ndi mtundu womwe anthu sangathe kugwiritsa ntchito mwachilengedwe, zomwe zimalepheretsa kuthekera kwake ngati m'malo mwake.
Gululi lapanga njira ya biotechnology yomwe imagwiritsa ntchito kasamalidwe ka photon (mikhalidwe yabwino yowunikira) kuti iwonjezere kupanga vitamini B12 yogwira ntchito mu spirulina, komanso kupanga mankhwala ena ogwira ntchito m'thupi omwe ali ndi ntchito zotsutsana ndi antioxidant, anti-inflammatory, komanso chitetezo chamthupi. Njira yatsopanoyi imatha kupanga biomass yokhala ndi michere yambiri komanso kukwaniritsa kusagwirizana ndi kaboni. Vitamini B12 yogwira ntchito m'chilengedwe choyeretsedwa ndi 1.64 micrograms / 100 gramu, pomwe mu ng'ombe ndi 0.7-1.5 micrograms / 100 gramu.
Zotsatira zake zikusonyeza kuti kulamulira photosynthesis ya spirulina kudzera mu kuwala kungapangitse kuti thupi la munthu likhale ndi vitamini B12 yogwira ntchito, zomwe zimapangitsa kuti pakhale njira ina yokhazikika m'malo mwa zakudya zachikhalidwe zochokera ku nyama.
