W artykule zostały przedstawione najnowsze osiągnięcia w zastosowaniu bionanotechnologii do otrzymywania nanocząstek metali. Szczególną uwagę poświęcono nanocząstkom srebra i złota oraz ich zastosowaniu. Nanocząstki metali, które są syntezowane przez mikroorganizmy, mogą być ulokowane wewnątrz, jak i na zewnątrz komórek tych mikroorganizmów. Do otrzymywania nanocząstek metali można także wykorzystać...
The biooxidation of gold-bearing arsenic concentrate from mining tailing was investigated. The strain of Thiobacillus ferrooxidans isolated from the Zloty Stok tailing heaps was used. The chemical and biooxidation processes were monitored by checking the ferrous, ferric and arsenic concentration in the leaching solution. Leaching experiments, were conducted using both coarse (-0.5 +0.125 mm) and fine...
