Abstract
A method for removing iodine by using Deinococcus radiodurans having a gold nanoparticle synthesis ability is disclosed. More particularly, a method for removing radioactive iodine by adsorbing radioactive iodine onto gold nanoparticles synthesized in cells of Deinococcus radiodurans is disclosed. A recombinant microorganism having an enhanced radioactive iodine removal ability according to the present invention may selectively remove radioactive iodine present in various types of solutions at a high efficiency of 99% or higher, and thus may be very effective in removing radioactive iodine generated in large-scale hospitals, industries, nuclear facility accidents, and the like.
