IMPROVED PRODUCTION OF RIBOFLAVIN

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...

Zusammenfassung:	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%. Procédé amélioré de production de vitamine B2 à l'aide d'une cellule hôte génétiquement modifiée comprenant une enzyme hétérologue présentant une activité de pyridoxal phosphatase. L'utilisation de ladite cellule hôte modifiée permet l'augmentation du rendement de production de riboflavine d'au moins environ 5 %.
