Metal recovery method, metal recovery carrier and metal bioreactor using the same

摘要

PROBLEM TO BE SOLVED: To provide a metal recovery method which can be used under a wide range of conditions without being restricted by its applicable range. SOLUTION: The metal recovery carrier is brought into contact with a medium containing metal ions, the metal ions contained in the medium are bonded to the outer layer surface of the metal recovery carrier, and the metal recovery carrier is removed from the medium. In the method for recovering a metal, the carrier for recovering a metal is a non-life activator having an outer layer composed of a phospholipid bilayer, and the porcine derived from Gram-negative bacteria is the phospholipid bilayer. A metal ion-binding peptide motif is introduced into a region that does not impair the porin function in the Gram-negative bacterium in the amino acid sequence of the porin that penetrates the membrane, and the metal ion-binding peptide motif is the phospholipid bilayer membrane. A method for recovering metal, which is presented on the surface of a metal. [Selection diagram] None
