Astronauti \u017eij\u00edc\u00ed na palub\u011b Mezin\u00e1rodn\u00ed vesm\u00edrn\u00e9 stanice pot\u0159ebuj\u00ed ke p\u0159e\u017eit\u00ed tot\u00e9\u017e, co my: j\u00eddlo, vodu k pit\u00ed a kysl\u00edk k d\u00fdch\u00e1n\u00ed. Tyto z\u00e1soby se na stanici dopravuj\u00ed ze Zem\u011b pomoc\u00ed n\u00e1kladn\u00edch lod\u00ed. P\u0159edstavte si v\u0161ak, \u017ee jste astronaut na vesm\u00edrn\u00e9 lodi budoucnosti a cestujete na vzd\u00e1lenou planetu. Budete p\u0159\u00edli\u0161 daleko od Zem\u011b na to, abyste mohli dost\u00e1vat jak\u00e9koli z\u00e1soby. Jak z\u00edsk\u00e1te to, co pot\u0159ebujete k p\u0159e\u017eit\u00ed? Aby pomohli vy\u0159e\u0161it tento probl\u00e9m, v\u011bdci v sou\u010dasn\u00e9 dob\u011b prov\u00e1d\u011bj\u00ed na Mezin\u00e1rodn\u00ed vesm\u00edrn\u00e9 stanici experiment zam\u011b\u0159en\u00fd na v\u00fdrobu kysl\u00edku.<\/p>\n<\/div>\n

V\u011bd\u011bli jste, \u017ee kdy\u017e lid\u00e9 d\u00fdchaj\u00ed, vdechuj\u00ed kysl\u00edk a vydechuj\u00ed oxid uhli\u010dit\u00fd? Rostliny to d\u011blaj\u00ed naopak: p\u0159em\u011bnou sv\u011btla na energii (proces zvan\u00fd fotosynt\u00e9za) p\u0159ij\u00edmaj\u00ed oxid uhli\u010dit\u00fd a uvol\u0148uj\u00ed kysl\u00edk. P\u0159\u00edtomnost rostlin ve vesm\u00edru by tedy mohla b\u00fdt skv\u011bl\u00fdm zp\u016fsobem, jak recyklovat vzduch pro astronauty. C\u00edlem experimentu v\u011bdc\u016f je zjistit, zda fotosynt\u00e9za funguje ve stavu bezt\u00ed\u017ee ve vesm\u00edru stejn\u011b jako na Zemi.<\/p>\n

Do laborato\u0159e Columbus agentury ESA na Mezin\u00e1rodn\u00ed vesm\u00edrn\u00e9 stanici byl p\u0159ivezen zvl\u00e1\u0161tn\u00ed druh bakterie zvan\u00fd Arthrospira, kter\u00e1 prov\u00e1d\u00ed fotosynt\u00e9zu podobn\u011b jako rostlina. Pot\u00e9 byla um\u00edst\u011bna do za\u0159\u00edzen\u00ed zvan\u00e9ho fotobioreaktor, co\u017e je v\u00e1lcovit\u00e1 n\u00e1doba s velk\u00fdm mno\u017estv\u00edm sv\u011btla. Arthrospira p\u0159ij\u00edm\u00e1 oxid uhli\u010dit\u00fd vydechovan\u00fd astronauty a p\u0159em\u011b\u0148uje jej na kysl\u00edk. Nav\u00edc lze z Arthrospiry snadno vyrobit takzvanou spirulinu, kter\u00e1 je velmi v\u00fd\u017eivn\u00e1 a astronauti ji mohou konzumovat!<\/p>\n

Hlavn\u00ed ot\u00e1zkou nyn\u00ed je, zda pobyt ve vesm\u00edru ovliv\u0148uje \u00fa\u010dinnost rostlin p\u0159i produkci kysl\u00edku. Pom\u00e1h\u00e1 jim stav bezt\u00ed\u017ee k vy\u0161\u0161\u00ed \u00fa\u010dinnosti, nebo zp\u016fsobuje podivn\u00e9 vedlej\u0161\u00ed \u00fa\u010dinky? Pom\u00e1h\u00e1 tomuto procesu vesm\u00edrn\u00e9 z\u00e1\u0159en\u00ed, nebo mu naopak \u0161kod\u00ed? Odpov\u011b\u010f se brzy dozv\u00edme.<\/p>\n

Mo\u017en\u00e1 se v budoucnu stane\u0161 astronautem, kter\u00fd bude cestovat do jin\u00e9ho sv\u011bta a d\u00fdchat vzduch recyklovan\u00fd rostlinami!<\/p>\n
