摘要:
A process is provided for producing &ggr;-decalactone using Yarrowia lipolytica HR 145 (DSM 12397). The process includes preparing the product in a bioreactor by culturing the pure strain of Yarrowia lipolytica in a culture medium containing carbon compounds, nitrogen compounds, inorganic salts, trace elements, vitamins, etc. Other ingredients of the culture medium include glycerol, glucose, mannitol, citric acid, malt extract, yeast extract, casein hydrolysate, castor oil, cotton seed meal or corn steep liquor. Also sulphates, nitrates, chlorides, carbonates or phosphates of metals sodium, potassium magnesium, manganese, calcium, zinc, and mixtures thereof can be used in the culture medium. Further, a pure strain of Yarrowia lipolytica HR 145 (DSM 12397) is provided.
