Полирезистентность и сверхустойчивость к тяжелым металлам антарктических микроорганизмов
It is shown for the first time, that in Antarctic Region (island Galindez of the Argentine archi- pelago) are occurred the microorganisms which are resistant to high concentrations of toxic heavy metals. The microorganisms which grow under aerobic conditions in the presence of 200–500 ppm Hg2+, 1000–...

It is shown for the first time, that in Antarctic Region (island Galindez of the Argentine archi- pelago) are occurred the microorganisms which are resistant to high concentrations of toxic heavy metals. The microorganisms which grow under aerobic conditions in the presence of 200–500 ppm Hg2+, 1000–3000 ppm Cu2+, and 3000–60000 ppm CrO2− 4 are isolated. Mi- croorganisms are characterized by a polyresistance to metals (Hg2+, Cu2+ and CrO2− 4 ). They grow in the presence of these three metals separately and in their mixture. On adding glucose to a nutrient medium (20 g/l), microorganisms reduce CrO2− 4 up to insoluble Cr(OH) . 3nH2O.
