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 the lignin-derived aromatic, syringaldehyde (SYAL).
They: are polymeric substances derived from 3-<i>O</i>-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. Their activity is particularly
rare and the biotransforming capabilities will contribute to the development
of new basic techniques for the effective utilization of lignin.
