Reduction radioactive of waste ion exchange resin with microorganism enzyme

We were searching the microorganisms which could eliminate the isotope absorbed to ion exchange resin in a nuclear power plant. For this purpose, we prepared the ion exchange resin absorbed metal (Ni) as a model system. We selected a few microorganisms which could strongly separate Ni from the resin. Using the enzyme extracted from the microorganism, we tried the elimination and collection of Ni from the model resin. The elimination rate of Ni from the resin was more than 90%. And we examined the resistance of the microorganisms exposed to isotope. (author)
