    摘要: The present invention relates to the production of recombinant microorganisms, in particular of the genus Gluconobacter, for production of 2-keto-L-gulonic acid (2-KGA) and/or L-ascorbic acid (hereinafter also referred to as Vitamin C), wherein the microorganism has been modified to overexpress L-sorbose dehydrogenase (SDH). This overexpression has been achieved by introducing of one or more copies of a polynucleotide encoding SDH into the genome of the host microorganism resulting in enhanced yield, production, and/or efficiency of 2-KGA production and/or Vitamin C compared to a non-modified microorganism. Expression of said one or more extra-copies of sdh is dependent on the integration site. The invention also relates to genetically engineered microorganisms and their use for the production of 2-KGA and/or Vitamin C.
