発明の名称 (英語) METAL RECOVERY METHOD, METAL RECOVERY CARRIER, AND METAL RECOVERY BIOREACTOR USING SAME 新技術説明会
発明の概要(英語) [Problem] To provide a metal recovery method capable of being used in a wide range of conditions without limitation upon range of applicability.
[Solution] A metal recovery method in which a metal recovery carrier and a medium containing metal ions are brought into contact, the metal ions in the medium are bonded to the surface of an outer layer of the metal recovery carrier, and the metal recovery carrier is separated from the medium. The outer layer of the metal recovery carrier is a biologically inactive material constituted by double phospholipid films. Porins derived from gram-negative bacteria pass through the double phospholipid films. A metal ion bonding peptide motif is introduced into a region of the amino acid sequence of the porins that will not negatively affect porin functioning in the gram-negative bacteria. The metal ion bonding peptide motif is presented on the surfaces of the double phospholipid films.
従来技術、競合技術の概要(英語) BACKGROUND ART
Catalyst to be used in petroleum refining processes, the active ingredient of a preservative, an industrial oil additives, electrical, electronic apparatus, the antibacterial agent is used in the medical field, a transition metal, noble metal, a rare, a single metal such as ground, or a metal oxide or sulfide is widely used. Of these metals as a high rarity value is also included therein. Industrial waste water or waste water is utilized in production, heavy metal or heavy metal compound is toxic to the human body that may be contained at a high concentration. Such waste if contaminated soil or water quality, a single metal or a metal compound needs to be removed. On the other hand, a sewage treatment plant or waste processing such as processes and sludge produced in the course of, the metal of the magnet in the sludge, rare high rarity value, if the ground is included. For this reason, a single metal or metal compound (hereinafter, these are collectively referred to as' metal '), or a method for the efficient recovery of these ions is demanded.
Conventional, metal recovery method, recovery of the metals chemically general method. However, many metal chemical energy is required and the recovery method, a large load on the environment. Therefore, energy consumption can be reduced, the load on the environment is small, a metal recovery method is sought.
Energy consumption can be reduced, the load on the environment as a method for metal or of the ions is small, the recovery method using a microorganism has attracted attention in recent years (biosorption). Patent Document 1 and 2 is for example, E. coli gene or metal binding gene metal uptake ( Escherichia coli) introduced, the resulting transformed cells of the method of introducing a transition metal and heavy metals have been described. Further, in the non-patent document 1, a transmembrane protein of E. coli cells by altering the OmpA binding ability to cadmium in the E. coli is a method.
