Outline of Final Research Achievements

We have established a production system for 2-pyrone-4,6-dicarboxylic acid (PDC) as a novel platform chemical from lignin via fermentation by genetically-modified bacterial. We have also successfully synthesized various polymers such as polyesters, polyamides and polyurethanes from PDC. Unexpectedly, we have also now discovered a unique function of PDC as an alkali metal chelator. In this research, PDC preferentially chelated 133Cs as compared to other Alkali metals. 133Cs was precipitated as a Cs-PDC complex. PDC was able to remove about 90% of Cs in a mixed Na-Cs solution, even when the concentration ratio of Na and Cs was 10 to 1. Comparing the structures of the Cs-PDC and Na-PDC complexes, the Cs-PDC complex does not contain water and it is larger than the Na-PDC complex. The size and hydrophobic nature of the Cs-PDC complex explains why it more readily precipitates in water compared to the Na-PDC complex.
