Abstract
Several heterotrophic bacteria that solubilized PbS were isolated from soil. Depending on the isolate and medium composition, the isolates solubilized 0.3-56 .mu.g Pb2+ per/ml of medium during 24 h of active growth. The organisms also solubilized ZnS, CdS and CuS, but had no activity against PbSO4, PbO or Pb3O4. The isolates produced neither 2-ketogluconic acid or siderochromes, suggesting that the organisms produce a previously undescribed solubilizing agent.Keywords
