| biofilm formation by algae as a mechanism for surviving on mine tailings. | photosynthetic biofilms successfully colonize the sediments of a mine tailings reservoir (guanajuato, mexico) despite the high metal concentrations that are present. to elucidate the mechanisms of biofilm survival despite metal ores, experiments were performed to evaluate the response of seminatural biofilms to cu, zn, and a combination of both metals at concentrations observed in the field. the biofilms were composed mostly of the chlorophyte chlorococcum sp. and the cyanobacterium phormidium s ... | 2005 | 15779756 |
