[Consumption of amino acids by Escherichia coli--a producer of recombinant proteins].

The dynamics of amino acid consumption from the medium by Escherichia coli 1864, a strain producing recombinant protein was studied. It was shown that the strain actively used glutamate and aspartate from the medium, which was determined by the leading role of the amino acids in nitrogen metabolism. The strain also consumed threonine, glycine and alanine capable of effectively providing the culture with metabolic energy.
