| Popis: | Study of the submicroscopic structure of oxide ores revealed their similarity to the present-day bacterial communities. It was shown that the structure of cobalt-bearing crusts and ferromanganese nodules is based on bacterial mats, which permits identifying them as stromatolites and oncolites. Data that support intense interaction between biofilms and the environment were found. Signs of formation of the mineral phase as a result of biochemical absorption and assimilation of iron and manganese by bacteria were observed. |
