Abstract

PURPOSE: To prepare efficiently a great amount of L-histidine, by cultivating aerobically a facterium having specific properties, belonging to the genus Escherichia, in a liquid medium so that L-histidine is formed in a medium.
CONSTITUTION: A bacterium belonging to the genus Escherichia, having 2-thiazolealanine and 1,2,4-triazolealanine resistance, and L-histidine producing ability, is cultivated in a liquid medium to form and acumulate L-histidine, which is collected. Escherichia coli AJ11375 FERM-P5035, Escherichia coli AJ11376 FERM-P5036, etc. may be cited as the bacterium. A carbohydrate, organic acid, alcohol, etc. may be cited as a carbon source of the culture medium: ammonium sulfate, etc., as a nitrogen source. The cultivation is preferably carried out in a pH of 5W9.20 at 20W45°C under aerobic conditions for 20W96hr.
