Abstract
This invention relates to a biocatalytic process to produce terephthalic acid and isophthalic acid from p-xylene and m-xylene, respectively. Terephthalic acid has been prepared by oxidizing p-xylene with bacteria belonging to the genus Burkholderia. Conversion of p-xylene into terephthalic acid is accomplished by a single bacterial strain that produces all of the requisite enzymes. In addition, this invention relates to the preparation of isophthalic acid from a mixture of m- and p-xylene.
