  • Production of ?-keto butyrate
    Patent number: 7144715
    Abstract: A process of obtaining ?-keto butyrate by bioconversion is disclosed. The molecule is accumulated in the medium and is apt to subsequent processing to food ingredients, such as top-note flavors. A suitable strain is a natural ilv-3 mutant Neurospora crassa strain, which is capable of accumulating ?-keto butyrate in the fermentation medium. By adjusting specific medium parameters, up to 8 g/l medium of ?-keto butyrate can be accumulated.
