Process for the preparation of saturated delta lactones by biohydrogenation of the corresponding insaturated compounds by microorganisms.

摘要

The production of natural delta-decanolide and/or delta-dodecanolide or mixtures thereof by means of biohydrogenation of a substrate containing the corresponding unsaturated lactones, respectively, delta-decen-2-olide, delta-dodecen-2-olide and mixtures thereof, is carried out using a microorganism chosen from the group consisting of Saccharomyces delbrueckii, Pichia ohmeri, Hansenula anomala, Pichia stipitis, Debaryomyces hansenii, Zymomonas mobilis, Zygosaccharomyces rouxii, Schawnniomyces occidentalis, Sarcina lutea, Geotrichum candidum.
