Abstract
Method for stereoselectively preparing a (R) or (S) gamma-lactone consists in microbially biosynthesizing gamma-lactone, wherein the biosynthesis is carried out from a substrate selected from C5 to C20 fatty acids with the aid of a strain selected from those enabling a stereoselective hydroxylation in C4 of the substrate, in particular Aspergollus sp or Mortierella sp. The biosynthesis of the gamma-lactone and the use thereof in perfumery and for food flavouring agents are also disclosed.
