摘要： The present disclosure discloses a method for preparing natural delta-decalactone and delta-dodecalactone by bioreduction of Massoia Oil, which comprises (1) Strain activation, (2) Preparation of seed culture solution, (3) Fermentation and conversion, (4) Extraction, (5) Solvent recycle, and (6) Rectification. The present disclosure has a higher space-time yield relative to the existing techniques and obtains a higher product concentration. The Saccharomyces pastorianus OMK-70 was obtained by multiple rounds of strain mutagenesis of the present disclosure is used to ferment and reduce δ-lactone of 5-hydroxy-2-decenoic acid and δ-lactone of 5-hydroxy-2-dodecenoic acid in Massoia Oil. Which has a higher effectiveness, thus the production cost is greatly reduced. It has good industrial application prospects.
