Evidence of Resistance of Heavy Metals from Bacteria Isolated from Natural Waters of a Mining Area in Mexico

This study focuses on identifying relationships between the content of heavy metals in water and resistance patterns different bacteria. Samples from watercourses one most important mining areas Mexico were collected. Seventy-one bacteria isolated, their to Cr, Zn, Cu, Ag, Hg, Co was studied. The Minimum Inhibitory Concentration range determined, a Multiple Metal Resistant index calculated. After that, 11 isolated chosen estimate kinetic parameters. obtained results show differences behavior studied concerning presence media: (1) without effect, (2) inhibited growth; (3) considerable growth. Finally, Performance Index proposed select adequate for removal; five selected. Among them, Pseudomonas koreensis identified as good candidate future biosorption system since these can stimulate growth all tested.
