Abstract
A method of biologically producing an terephthalic acid or a derivative thereof by contacting a substrate containing an aromatic carboxylic acid with a biocatalyst that adds a carboxyl group at the para-position of the aromatic carboxylic acid.
Claims22
A method of biologically producing an terephthalic acid or a derivative thereof represented by Chemical Formula 1, comprising contacting a substrate containing an aromatic carboxylic acid represented by Chemical Formula 2 with a biocatalyst that adds a carboxyl group at para-position of the aromatic carboxylic acid:
- wherein, X and Y are independently hydrogen, hydroxy, or C1-C4 alkoxy.
A method of biologically producing a terephthalic acid or a derivative thereof represented by Chemical Formula 1, the method comprising
- contacting a substrate containing an aromatic carboxylic acid of Chemical Formula 3 having a para-hydroxy group with a biocatalyst that removes the para-hydroxy group to provide an aromatic carboxylic acid of Chemical Formula 2;
- and contacting the aromatic carboxylic acid of Chemical Formula 2 with a biocatalyst that adds a carboxyl group at para-position of the aromatic carboxylic acid to provide a terephthalic acid or a derivative thereof represented by Chemical Formula 1:
- wherein X and Y are independently hydrogen, hydroxy, or C1-C4 alkoxy.
A method of biologically producing a terephthalic acid or a derivative thereof represented by Chemical Formula 1, the method comprising
- providing a substrate comprising an aromatic aldehyde of Chemical Formula 4;
- converting the aromatic aldehyde of Chemical Formula 4 to an aromatic carboxylic acid of Chemical Formula 3 by chemical oxidation or biocatalytic oxidation;
- contacting the aromatic carboxylic acid of Chemical Formula 3 having a para-hydroxy group with a biocatalyst that removes the para-hydroxy group to provide an aromatic carboxylic acid of Chemical Formula 2;
- and contacting the aromatic carboxylic acid of Chemical Formula 2 with a biocatalyst that adds a carboxyl group at para-position of the aromatic carboxylic acid to provide a terephthalic acid or a derivative thereof represented by Chemical Formula 1:
- wherein X and Y are independently hydrogen, hydroxy, or C1-C4 alkoxy.
