I hundreder af \u00e5r har man i Sydamerika og Afrika h\u00f8stet en s\u00e6rlig bakterieart kaldet spirulina. Den omdanner kuldioxid til ilt, vokser meget hurtigt, og \u2013 m\u00e5ske det bedste af alt \u2013 kan blandes i f\u00f8devarer for at \u00f8ge deres proteinindhold.<\/p>\n<\/div>\n

Forskere fra ESA\u2019s team for mikro\u00f8kologiske alternative livsst\u00f8ttesystemer (forkortet MELiSSA) har unders\u00f8gt alt, hvad de kan, om spirulina. Det kunne v\u00e6re den ideelle rummad, da det kan forarbejdes til snacks, der holder astronauterne tilfredse og sunde. ESA-astronauterne Samantha Cristoforetti og Andreas Mogensen har allerede spist spirulina-m\u00f8rbr\u00f8dst\u00e6nger i rummet!<\/p>\n

Nu bliver denne viden om spirulina brugt til at hj\u00e6lpe mennesker her p\u00e5 Jorden. I Congo ligger der en by ved navn Bikoro. Befolkningen der spiser en plante, der hedder kassava, men desv\u00e6rre bidrager den ikke med ret meget protein til deres kost. Kunne spirulina v\u00e6re en hj\u00e6lp?<\/p>\n

\"\"<\/figure>\n

En gruppe forskere fra MELiSSA mener i hvert fald det. De har etableret en base i byen og dyrker spirulina i store vandkar. Ved at tils\u00e6tte et kemikalie kaldet kaliumbicarbonat til vandet sammen med et par andre let tilg\u00e6ngelige ingredienser vokser spirulina meget hurtigt. Den kan derefter forarbejdes til pulver og drysses p\u00e5 mad lavet af kassava, hvor den tilf\u00f8jer det s\u00e5 n\u00f8dvendige protein \u2013 og som en bonus ogs\u00e5 A-vitamin og jern!<\/p>\n

MELiSSA-teamet ser frem til at forts\u00e6tte sin forskning i spirulina. Det n\u00e6ste skridt er at sende levende spirulina op til Den Internationale Rumstation og unders\u00f8ge den i ESA\u2019s Columbus-laboratorium. Ingen ved endnu, om spirulina vil trives i v\u00e6gtl\u00f8shed. Men hvis den g\u00f8r det, vil fremtidige astronauter m\u00e5ske dyrke denne superf\u00f8devare under lange rejser langt ud i solsystemet!<\/p>\n
