Peroxisomal Î²-oxidation and Production of Î³-decalactone by the Yeast Rhodotorula aurantiaca
AbstractÎ³-Decalactone is a fruity aroma compound resulting from the peroxisomal Î²-oxidation of ricinoleic acid by yeasts. During the Î²-oxidation of fatty acids, the acyl-CoA oxidase and thioesterase play an important role. In R. aurantiaca, we demonstrated the presence of partial gene sequences homologous to acyl-CoA oxidase and thioesterase involved in the pathways synthesis of Î³-decalactone. This preliminary work is expected to characterize the relationship between the Î³-decalactone production and the transcription of these partial gene sequences of R. aurantiaca probably involved in the oxidation of ricinoleic acid.
