Abstract
Provided are a novel microorganism and a method for purifying 2,6-naphthalene dicarboxylic acid with high purity using the microorganism. The microorganism is Pseudomonas sp. Strain HN-72 isolated from soil and has the ability to convert 2-formyl-6-naphthoic acid contained as an impurity in a crude naphthalene dicarboxylic acid, which is an oxidation product of 2,6-dimethylnaphthalene, to 2,6-naphthalene dicarboxylic acid. The Pseudomonas sp. strain HN-72 has excellent effects in producing high-purity 2,6-naphthalene dicarboxylic acid in high yield.
