PROBLEM TO BE SOLVED: To provide 5-phenyl-4-hydroxyvaleric acid.SOLUTION: A cultured bacterial cell of a microorganism is provided which can selectively convert catechins or a catechin derivative as a starting material to 5-phenyl-4-hydroxyvaleric acid and/or 5-phenyl γ-valerolactone. A method is also provided for extremely easily producing an objective compound by which a starting material is anaerobically incubation-processed in the presence of a preparation of the cultured bacterial cell. When a catechin derivative is used as a starting material, the microorganism can include ones belonging to any genus of Eubacterium or Eclostridium. When catechins is used as a starting material, it is necessary to use a microorganism belonging to the genus of Eggerthella or Edlercreutzia, in addition to the microorganisms. |
