Outline of Final Research Achievements

The lichen fungi of the metal-hyperaccumulator lichen Stereocaulon japonicum were cultured; the effect of Cs addition on it and the Cs adsorption capacity of it were investigated. The results suggest that it is suitable for Cs adsorbent.
The sugar-alcohol analysis system including the apparatus, which was purchased in this study, in combination with our existing apparatus was developed. Using this system, the negative correlation between metal and sugar-alcohol concentrations in the lichen growing in metal-contaminated environments was found, revealing the effect of metal pollution on sugar-alcohols in lichens.
