Abstract

PURPOSE:To obtain the titled optically active compound without carrying out operation to separate by-products, by adding a trimethyl-cyclohexene-diol to a culture fluid of a specific microorganism, cultivating the microorganism, then adding another microorganism and cultivating the afore-mentioned microorganism. CONSTITUTION:(A) 3,5,5-Trimethyl-2-cyclohexene-1,4-dione is added to (B) a culture fluid of a microorganism (e.g. thermomonospora curvata IFO 12384), belonging to the genus Thermomonospora and having the ability to convert the component (A) into 2,2,6-trimethyl-1,4-cyclohexanedione to carry out cultivation at, e.g. 48-51 deg.C. (C) A microorganism [e.g. Bacillus stearothermophilus NK-0151 strain (FERM P-8894)], belonging to the genus Bacillus and having a higher optimum growth temperature than that of the component (B) is added and cultivated, preferably at 51-55 deg.C to remove the microbial cells and extraction, etc., are carried out to provide the aimed 4-hydroxy-2,2,6- trimethylcyclohexanone.
