<p>Provided is a process for producing a diol, which can efficiently produce a diol having a low intensity of abnormal odor and high purity. A process for producing 1-(2-hydroxyethyl)-2,5,5,8a-tetramethyldecahydronaphthalen-2-ol represented by formula (2):
the process containinng drying a culture fluid obtained by microbial conversion using a compound(s) represented by formula (1a) and/or (1b)
as a substrate, bringing the dried product of the culture fluid into contact with such a solvent that the SP value of the medium obtainable after the contact between the dried product of the culture fluid and the solvent falls in the range of 9.5 to 16 [(cal/cm 3 ) 1/2 ], subsequently removing the microorganism from the medium, and crystallizing the medium.</p> |
