Process for the preparation of a lactone

摘要

The present invention concerns a microbiological process for the production of gamma -decalactone. According to this process, a culture of the fungus of a particular species of the genus Mucor is incubated with the particular substrate, which is an organic carboxylic acid ester, to produce fermentatively the gamma -decalactone. According to the invention, exact conditions have now been discovered under which gamma -decalactone can be prepared in high yields. These conditions are based upon the fermentative incubation of a fungus of the genus Mucor in conjunction with the appropriate substrate in order to obtain the high yield of the desired lactone.
