| Research Abstract |
Catechin, that is one of the flavonoids, is secondary metabolite of plants, and is major precursor of condensed tannin that was the second most abundant aromatic biomass following lignin. Thus, it is very interested that how decomposed and carbon recycled the catechin, that was produced in large quantities by plants, by soil micro-organisms. In this study, we described that the OX-01 could convert(+)-catechin and(-)-epicatechin to protocatechuic acid via taxifolin. These results suggested that it is possible to design a system of raw material production from condensed tannin by using microbial function and acidic decompose reactions.
