title: A conservative region of the mercuric reductase gene (mera) as a molecular marker of bacterial mercury resistance.
abstract: The most common bacterial mercury resistance mechanism is based on the reduction of Hg(II) to Hg(0), 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.
