title: Screening of heavy metal-tolerant actinomycetes isolated from the Salí River.
abstract: Fifty-three strains of actinomycetes resistant to heavy metals were isolated from the Salí River in northwest Argentina. Screening procedures that involve solid and liquid synthetic media containing Cd(2+), Cu(2+), or Hg(2+) allowed the selection of six strains. These strains showed a quantitative sorption of Cd(2+) and Cu(2+) by more than 98% of the initial metal concentrations (0.1, 0.5, and 1.0 mM) tested.
