increased production of a target product via mRNA stabilization

A process for producing a vitamin with a microorganism, wherein said microorganism is incubated in an aqueous medium under conditions permitting the production of vitamin from a carbon source, and optionally wherein the vitamin is isolated, wherein said microorganism is genetically altered by introducing a polynucleotide leading to an enhanced production of vitamin produced by said microorganism performance and / or efficiency, selecting said polynucleotide from the group consisting of: (a) polynucleotides comprising the nucleotide sequence according to SEQ ID NO: 2; (B) and polynucleotides that are at least 95% identical to a polynucleotide as defined in (a) and having the activity of a stabilizing element of the mRNA, or the complementary strand of such a polynucleotide.
