| Abstract: | The susceptibility of obligate methane-utilizing bacteria, including 14 reference strains and 175 environmental isolates, to five readily available heavy metal pollutants was determined. The chloride salts of Hg(II), Cd(II), Cu(II), Cr(III) and Zn(II) were tested in a system free from organic matter. Methane-utilizers appeared to have relatively discrete metal tolerance patterns with resistances to all metals varying with isolation site. Methanotrophs proved to be quite sensitive to mercury and cadmium but relatively resistant to copper, chromium and zinc |
