  • Fermentation Process
    Publication number: 20120196323
    Abstract: The present invention relates to a fermentation process for culturing a host cell comprising a vector which comprises an inducible promoter of the mannose operon wherein the inducible promoter of the mannose operon controls expression of a nucleic acid sequence encoding for a polypeptide, in particular the present invention relates to the high cell density fermentation of a prokaryotic host cell comprising the inducible promoter of the mannose operon in the production of a polypeptide.
