The present invention relates to a method for producing metal nanoparticles and metal sulfide nanoparticles using recombinant microorganisms that simultaneously express phytokeratin synthase and metallothionein, which are heavy metal adsorption proteins, and metal nanoparticles synthesized by the above method. It relates to the use of particles or metal sulfide nanoparticles. According to the present invention, by providing a method for synthesizing a metal, which has been difficult to synthesize by a conventional biological method, in the form of a nanoparticle, it is possible to synthesize metal nanoparticles in a new environmentally and economically manner. In addition to making it possible to synthesize metal sulfide nanoparticles using sulfur, metal nanoparticles produced by conventional chemical or biological methods can also be produced using the production method of the present invention. Was increased significantly. |
