  • Publication number: 20120276598
    Abstract: A method for efficiently producing an L-amino acid, especially L-lysine, by using a ?-proteobacterium is provided. In a method for producing an L-amino acid comprising culturing a bacterium belonging to ?-Proteobacteria and having an ability to produce an L-amino acid, for example, an Enterobacteriaceae bacterium such as Escherichia coli, in a medium containing glycerol as a carbon source to produce and accumulate the L-amino acid in the medium, and collecting the L-amino acid from the medium, a bacterium modified so that the activity of the Cnu protein is reduced is used as the bacterium.

  • Publication number: 20120270279
    Abstract: The present invention provides a methodology for improving a yield of 2R,4R-Monatin. Specifically, the present invention provides a method for producing 2S,4R-Monatin or a salt thereof, comprising contacting 4R-IHOG with an L-amino acid aminotransferase in the presence of an L-amino acid to form the 2S,4R-Monatin; a method for producing 2R,4R-Monatin or a salt thereof, comprising isomerizing the 2S,4R-Monatin to form the 2R,4R-Monatin; and the like. These production methods may further comprise condensing indole-3-pyruvate and pyruvate to form the 4R-IHOG, and deaminating a tryptophan to form the indole-3-pyruvate.

  • Publication number: 20120270281
    Abstract: Methods and systems for increasing the production of monatin in a multi-step equilibrium pathway are described. Tryptophan and pyruvate are added to a bioreactor to form a mixture comprising monatin and a plurality of intermediates via a multi-step equilibrium pathway. The methods and systems include operating the bioreactor such that a temperature of the mixture in the bioreactor is less than 25 degrees Celsius, resulting in an increased production of monatin. In some embodiments, the temperature of the mixture in the bioreactor is between about 5 degrees Celsius and about 23 degrees Celsius; in other embodiments, the temperature is between about 10 degrees Celsius and about 18 degrees Celsius.
