Ten native actinomycete strains were isolated from water and sediment samples collected in La Conejera wet-lands to assess mercury resistance and detoxification ability for evaluating the presence of the mer A gene involved in that process. Sensitivity assays were performed using 3.68 x 10-3 mM to 10 mM HgCl2 concentrations. Growth curves were generated for each resistant strain after 192 h in discontinuous fermentation in medium supplemented with 0.01 mM and 0.05 mM HgCl2. Biomass growth was then measured by dry weight, maximum value (2.37 g�L-1) being obtained after 72 h. Primer pairs were designed based on the sequence encoding the mercury-reductase enzyme in Streptomyces lividans 1326. PCR conditions for amplifying that region were stan...
