Abstract: | Pseudomonas putida strain S4, when starved of carbon source, precipitated Cu2+ in the medium. The precipitate, apart from containing copper, consisted of phosphate and hydroxide residues. While high acid phosphatase activity provided the necessary phosphates for Cu2+-precipitation, hydroxyl residues generated by metal efflux pathway may be used for metal hydroxide precipitation. This phenomenon could be exploited in the biorecovery of copper from different sources. |
