  • OPTIMIZATION OF C-8 STEROL ISOMERIZATION
    Publication number: 20210238539
    Abstract: The present invention is related to an improved method for production of 7-dehydrocholesterol (7-DHC), an important intermediate towards biotechnological production of vitamin D3 or derivatives/metabolites thereof. The invention features modified yeast strains expressing enzymes having improved C-8 sterol isomerase activity leading to increased ratios of 7-DHC in the sterol mix.
    Type: Application
