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 promoted bacterial adaptation to mercury. Failure to detect the mer gene in one mercury-contaminated sediment where phenotypic expression was low suggested that other mechanisms of resistance may partially determine the presence of mercury-resistant organisms in mercury-contaminated sediment or that the mercury in this particular sediment was very chemically limited in its availability to the microorganisms.
