  • IMPROVED PRODUCTION OF RIBOFLAVIN
    Publication number: 20220010291
    Abstract: The present invention is related to an improved process for production of vitamin B2 using a genetically engineered host cell comprising a heterologous enzyme with pyridoxal phosphatase activity. Using said modified host cell, the yield of riboflavin production could be increased by at least about 5%.

  • 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.

    Inventors: Christopher Mark FARRELL, Lisa Ann LAPRADE, Otto Martin LEHMANN, Joshua TRUEHEART, Bastien Jean Wolfgang CHEVREUX
  • OPTIMIZATION OF C-5 STEROL DESATURATION
    Publication number: 20210222222
    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 host strains expressing enzymes having improved C-5 sterol 5 desaturase activity and their use in a process for production of vitamin D3 or derivatives and/or metabolites thereof.
    Type: Application
    Filed: May 21, 2019
    Publication date: July 22, 2021

  • MODIFIED STEROL ACYLTRANSFERASES
    Publication number: 20210115412
    Abstract: The present invention is related to modified sterol acyltransferase enzymes with improved activity and/or specificity towards acylation of the vitamin D3 precursor 7-dehydrocholesterol (7-DHC) to be used in biotechnological production of vitamin D3. The invention further relates to a yeast strain expressing said modified enzymes and their use in a process for production of vitamin D3 or derivatives and/or metabolites thereof.
