    摘要: A process for preparing a 2-hydroxy-4-substituted pyridine compound using a microbiological method, a novel microorganism, and a novel compound are provided.According to the process, a function of a microorganism or a product obtained therefrom is exerted on a 4-substituted pyridine of the general formula (1): wherein R is a methyl group, a carboxyl group, a carbamoyl group, a hydroxyiminomethyl group or a cyano group, to obtain the corresponding 2-hydroxy-4-substituted pyridine compound. The novel microorganisms are the Delftia species YGK-A649 (FERM BP-10389), Delftia species YGK-C217 (FERM BP-10388), or Acidovorax species YGK-A854 (FERM BP-10387) and the novel compound is a 2-hydroxy-4-pyridinaldoxime.
