Abstract:
1. A method for recycling metals, comprising: culturing an isolated thermophilic bacterial strain in a culture medium; separating the thermophilic bacterial strain from the culture medium, wherein the culture medium comprises a mixture of extracellular proteins excreted by the thermophilic bacterial strain; concentrating the culture medium to a concentration of 50 ppm extracellular proteins, thereby obtaining a concentrated culture medium; contacting a volume of the concentrated culture medium with an equal volume of a liquid comprising metal ions, thereby forming a complex of the metal ions and the extracellular proteins, wherein the metal ions are from a metal to be recycled; collecting the complex of the metal ions and the extracellular proteins; adding a desorption agent to the complex of the metal ions and the extracellular proteins; wherein the isolated thermophilic bacterial strain is
