PRODUCTION OF HYDROXIDE OF PICOLINIC ACID OR PYRAZINIC ACID BY MICROORGANISM

摘要

PURPOSE:To produce a hydroxide of picolinic acid or pyrazinic acid in high purity and yield by using a microorganism. CONSTITUTION:Picolinic acid or pyrazinic acid is treated with a microorganism (its cultured liquid, cell or treated cell) belonging to genus Alcaligenes to obtain 6-hydroxypicolinic acid or 6-hydroxypyrazine-2-carboxylic acid.
