Mohli sme nahliadnu\u0165 do nepoznan\u00e9ho mikrosveta…tak by op\u00edsal svoj objav kolekt\u00edv z Katedry mikrobiol\u00f3gie.\u00a0<\/p>\n

Katedra mikrobiol\u00f3gie<\/strong> sa od svojho vzniku venuje extr\u00e9mofiln\u00fdm mikroorganizmom<\/strong>, teda tak\u00fdm, ktor\u00e9 \u017eij\u00fa v podmienkach nepredstavite\u013en\u00fdch pre \u017eivot<\/strong>. Posledn\u00e9 obdobie sa v\u00fdskumn\u00fd kolekt\u00edv zameriava najm\u00e4 na halofiln\u00e9, \u201eso\u013e-miluj\u00face\u201c bakt\u00e9rie. Tieto bakt\u00e9rie izolovali z vrtu v b\u00fdvalej so\u013enej bani v Pre\u0161ove. Toto prostredie je extr\u00e9mne z poh\u013eadu nedostatku \u017eiv\u00edn, extr\u00e9mne vysokej salinity (so\u013eanka je 10x slan\u0161ia ne\u017e morsk\u00e1 voda) a dlhodobej podpovrchovej priestorovej izol\u00e1cie od okolit\u00e9ho sveta v lo\u017eisk\u00e1ch soli star\u00fdch 16-17 mili\u00f3nov rokov.\u00a0<\/p>\n

P\u00f4vodn\u00fd z\u00e1mer prim\u00e1rneho z\u00e1chytu bol izol\u00e1cia halofilov s biotechnologick\u00fdm potenci\u00e1lom, produkuj\u00facich zauj\u00edmav\u00e9 extr\u00e9moenz\u00fdmy, bioplasty alebo degraduj\u00face r\u00f4zne polutanty. \u010cas\u0165 vzoriek v\u0161ak bola pou\u017eit\u00e1 na h\u013eadanie a kultiv\u00e1ciu bakt\u00e9ri\u00ed, ktor\u00e9 okrem toho \u017ee s\u00fa halofiln\u00e9 vyu\u017e\u00edvaj\u00fa ako jedin\u00fd zdroj energie s\u00edru.
