Document Type and Number:
Japanese Patent JP2008301719
Kind Code:
A
Abstract:
To make it possible to isolate catechol-degrading enzymes degrading the catechol even in an ammoniacal liquor of a special composition discharged from a coke oven from activated sludge of the ammoniacal liquor and utilize the catechol-degrading enzymes and to further provide a method for treating wastewater using the catechol-degrading enzymes.
