Culture-dependent and independent studies of microbial diversity in highly copper-contaminated Chilean marine sediments.

abstract：:The ability of strains of the genusRhodococcus to transform chlorinated phenolic compounds was studied. Noninduced cells of several strains ofRhodococcus, covering at least eight species, were found to attack mono-, di-, and trichlorophenols by hydroxylation at theortho position to chlorocatechols. 3-chlorophenol and ...
