Title:
MICROBIOLOGICAL PRODUCTION OF OPTICALLY ACTIVE GAMMA-LACTONE
Document Type and Number:
Japanese Patent JPH02174685
Kind Code:
A
Abstract:
PURPOSE: To effectively produce an optically active γ-lactone by bringing a vegetable oil, a hydrolysis product thereof or ricinolic acid into contact with a growing medium of specific microorganisms such as Aspergillus-niger.
CONSTITUTION: A growing medium of microorganisms selected from a group of Aspergillus-niger, Cladosporium-suaveoles, Phanerochaete-crysosporium and Pichia-etchellsii is prepared. One kind of a vegetable oil and a hydrolysis product thereof, or ricinolic acid is brought into contact with the before growing medium of the microorganisms to provide an optically active γ-lactone selected from γ-decalactone and γ-octalactone. A suitable example of the before vegetable oil is sunflower oil, coconut oil, etc.
