Abstract

Vectors and recombinant bacteria for overproducing riboflavin, in which nucleic acid overproducing riboflavin biosynthetic proteins is introduced in the chromosome of the host organism, e.g. at multiple sites and in multiple copies per site. A rib operon having at least five genes is used to make such recombinant bacteria.
