The present invention relates to a process for producing (4S)-4-hydroxy-2,6,6- trimethyl-2-cyclohexene-1-one (phorenol) from 2,6,6-trimethyl-2-cyclohexene- 1,4-dione (ketoisophorone) comprising contacting ketoisophorone with a microorganism which is capable of producing actinol from levodione or with a cell-free extract thereof, with a recombinant microorganism which is capable of producing actinol from levodione or with a cell-free extract thereof, or with levodione reductase, and isolating the resulting phorenol from the reaction mixture.

L'invention concerne un procédé de production de (4S)-4-hydroxy-2,6,6-triméthyl-2-cyclohexène-1-one (phorénol) à partir de 2,6,6-triméthyl-2-cyclohexène-1,4-dione (cétoisophorone) consistant à mettre en contact la cétoisophorone avec un micro-organisme pouvant produire de l'actinol à partir de lévodione ou d'un extrait exempt de cellules de lévodione, avec un micro-organisme recombiné pouvant produire de l'actinol à partir de lévodione ou d'un extrait exempt de cellules de celui-ci, ou avec une lévodione réductase. Ce procédé consiste également à isoler le phorénol obtenu à partir du mélange réactionnel.
