[Biosynthesis of somatotropin in a recombinant strain of Escherichia coli].

A recombinant Escherichia coli K-12 strain was grown in the regime of chemostat with glucose limitation at a different flow rate and in the regime of turbidostat. The stability of its population and the dynamics of somatotropin biosynthesis were studied. The plasmid-containing strain became less stable as the flow rate in the fermenter dropped down, which was due, apparently, to a greater limitation.
