The environmental impacts from metal accumulation cause disorders that often hinder recovery and control of these locations. This study evaluated the physical-chemical and microbiological parameters of water quality in a reservoir located in semiarid region of Rio Grande do Norte, Brazil (near a mining iron industry), as well as bioprospecting Chromobacterium violaceum (wild strains and ATCC 12472) for metal bioremediation, through investigation, comparison and inferential analysis of their phenotypic resistance patterns to iron, manganese and zinc metals in different exposure times, concentrations and interactions. The physicochemical water analysis revealed acceptable parameters, except the pH of the fifth site. In this site it was isolated C. violaceum. Both C. violaceum strains were resistant to metals tested in different exposure intervals, concentrations and interactions (p <10-5). However, it was observed that the wild strain showed a more efficient acute phase response when compared to the standard it, especially for metal concentrations between 80 – 48 (10-1 g/l). Zinc when interacting individually or jointly with metals iron and manganese increased resistance patterns in wild strain, whereas the reverse process was verified for ATCC strains. The bioprospecting tests demonstrated the importance of C. violaceum as a tool for metals bioremediation and highlight the importance of environmental monitoring and application of bioremediation in areas impacted by the aforementioned problem.
