The effects of mercury contamination of lake sediments on the phenotypic and genotypic mercury resistance of the indigenous heterotrophic aerobic bacterial communities were investigated. Strong positive correlations between mercury sediment concentration and the frequency of the gene coding for mercury volatilization (mer) (r = 0.96) or the phenotypic mercury resistance (r = 0.86) of the studied communities suggested that the inheritance via selection or genetic exchange of the mer gene had… CONTINUE READING
