US Patent 9279000 High-cell density fed-batch fermentation process for producing recombinant protein

Methods for producing proteins, for example, recombinant meningococcal 2086 proteins, using fed-batch fermentation with continuous input of an inducer after achieving a threshold parameter, and optionally continuous input of a carbon source, for example, a constant rate input, to improve protein yields, as well as high density protein compositions and compositions for use in the methods of the present invention, are provided.
