| Outline of Final Research Achievements |
We examined bacteria capable of transforming lignin-derived compounds into industrially or economically valuable substances from the seawater after the Great East Japan Earthquake-caused tsunami. Pseudomonas sp. ITH-SA-1 produced water-soluble fluorescent substances from lignin or its derivative, syringaldehyde (SYAL). They: are polymeric substances derived from 3-O-methyl gallate produced through transformation of SYAL via syringate; are not known compounds reported previously; have excitation/emission peaks at 365/498 nm, respectively; and have an average molecular weight of 7.2 kDa. Despite the fact that aromatic structure generally plays an important role in the planarity and rigidity of organic fluorescent substance, the spectroscopic analyses revealed that aromatic rings were not detected in the molecules.
