  • White rot fungi and method for degrading dioxins by using same
    Publication number: 20040142458
    Abstract: White rot fungi capable of decomposing dioxin were screened from rotten wood to isolate the MZ-340 strain. This MZ-340 could be cultured in the Kirk liquid medium (HCLN) or PDB medium. New systems that can be used to decompose dioxins in incineration ash were constructed using this MZ-340 strain. The present invention can decompose dioxins in incineration ash effectively and efficiently in both solid phase systems and liquid phase systems. Thus, the present invention enables the prevention of environmental pollution by dioxins generated during incineration and also the clean up of dioxin pollutants.
