Title:

CATECHOL-DEGRADING ENZYME AND METHOD FOR DEGRADING CATECHOL IN DRAINAGE WATER

Document Type and Number:

Japanese Patent JP2013055937

Kind Code:

A

Abstract:

To provide a catechol-degrading enzyme degradable of catechol even in ammonia water of specific composition discharged from a coke oven, which is isolated from ammonia water activated sludge to be utilizable, further to provide a method for treating drainage waster using the catechol-degrading enzyme.

There is provided a catechol-degrading enzyme encoded by DNA of a specific base sequence. The method for degrading catechol in drainage water comprises: mixing at least either catechol-degrading enzyme with drainage water containing catechol, and degrading catechol in the drainage water.
