Abstract
The present invention provides a transformed yeast strain containing a DNA sequence transcriptionally linked to a promoter functional in such yeast cells, which when expressed in a suitable host cell, encodes at least one polypeptide having riboflavin biosynthetic activity. Using such transformants, improved levels of riboflavin production are achieved. Processes of producing riboflavin from such transformants are also provided.
