2,6-PYRIDINECARBOXYLIC ACID OR ITS SALT, METHOD FOR PRODUCING THE SAME AND CHELATING AGENT

摘要

PROBLEM TO BE SOLVED: To obtain 2,6-pyridinedicarboxylic acid containing impurities which are also excellent in biodegradability. SOLUTION: A chelating agent having little load to the environment is provided by obtaining 2,6-pyridinedicarboxylic acid synthesized by microorganisms and which is excellent in biodegradability. The 2,6-pyridinedicarboxylic acid is obtained from an intermediate by modifying a lysine-biosynthetic pathway of a microorganism. As the microorganism, a strain capable of producing a large amount of lysine is preferably used e.g. it is preferable to use bacteria classified to Brevibacterium and Corynebacterium.
