There is provided a process for industrial production of simple 3-carboxy-cis,cis-muconic acid and/or 3-carboxymuconolactone from low molecular mixtures derived from plant components such as vanillin, vanillic acid and protocatechuic acid, via a multistage enzyme reaction. A recombinant plasmid containing a vanillate demethylase gene (vanAB genes), benzaldehyde dehydrogenase gene (ligV gene) and protocatechuate 3,4-dioxygenase gene (pcaHG genes); transformants incorporating the plasmid; and a process for production of 3-carboxy-cis,cis-muconic acid and/or 3-carboxymuconolactone characterized by culturing the transformants in the presence of vanillin, vanillic acid, protocatechuic acid or a mixture of two or more thereof.

Plasmid, transformants and process for production of 3-  carboxymuconolactone

A transformed plant expressing a DNA encoding secretory laccase from Coriolus versicolor, and a method of producing laccase are disclosed. Also disclosed is a method of decomposing and/or removing hazardous chemical substances by cultivating the transformed plant in an environment contaminated with the hazardous chemical substances.
