Abstract
A microbiological process for the production of 6-hydroxypicolinic acid starting from picolinic acid and/or its salts. The concentration of picolinic acid and/or its salts is selected so that the 6-hydroxypicolinic acid is not further metabolized. The process is performed either by microorganisms of genus Pseudomonas, Bacillus, Alcaligenes, Aerococcus, or Rhodotorula, or with biomass using picolinic acid, which grow with picolinic acid as the sole carbon, nitrogen and energy source.
Claims4
A microbiological process for the production of 6-hydroxypicolinic acid, characterized in that picolinic acid and/or at least one of its salts are hydroxylated by microorganism Alcaligenes faecalis, deposited in the DSM under number 6269, or one of its descendants or mutants, which grows with picolinic acid as sole carbon, nitrogen and energy source, and that the concentration of the picolinic acid and/or at least one of its salts is selected so that the 6-hydroxypicolinic acid is not further metabolized.
