Abstract

PURPOSE: To prepare a large amount of alanine, by culturing bacteria belonging to Escherichia genus and resistant to lysine-analog in a liquid medium under aerobic conditions.
CONSTITUTION: Bacteria resistant to lysine-analog and belonging to Escherichia genus, e.g. Escherichia coli AJ11383 (FERM-P No.5050) obtained by the induced mutation of Escherichia coli K-12, are inoculated in a liquid medium containing a carbon source, a nitrogen source, inorganic salts, and if necessary, organic minor nutrients, and cultured at pH5W9 and 20W45°C for 20W96hr under aerobic conditions. Alanine accumulated in the cultured product is separated by conventional means.
