SOTERO-MARTINS, Adriana et al. A conservative region of the mercuric reductase gene (merA) as a molecular marker of bacterial mercury resistance. Braz. J. Microbiol. [online]. 2008, vol.39, n.2, pp.307-310. ISSN 1517-8382.

The most common bacterial mercury resistance mechanism is based on the reduction of Hg(II) to Hg0, which is dependent of the mercuric reductase enzyme (MerA) activity. The use of a 431 bp fragment of a conservative region of the mercuric reductase (merA) gene was applied as a molecular marker of this mechanism, allowing the identification of mercury resistant bacterial strains.

Keywords : merA gene; mercury resistant; bacteria; molecular marker.
