Mineralization of chloroaniline/lignin conjugates and of free chloroanilines by the white rot fungus Phanerochaete chrysosporium

Lignin conjugates of (ring-U- super(14)C)-4-chloroaniline and (ring-U- super(14)C)-3,4-dichloroaniline were prepared enzymatically and characterized by gel permeation chromatography and chemical degradation. These samples, as well as the free (ring-U- super(14)C)chloroanilines and a control lignin w...

Description
Summary:Lignin conjugates of (ring-U- super(14)C)-4-chloroaniline and (ring-U- super(14)C)-3,4-dichloroaniline were prepared enzymatically and characterized by gel permeation chromatography and chemical degradation. These samples, as well as the free (ring-U- super(14)C)chloroanilines and a control lignin were fermented with the white rot fungus Phanerochaete chrysosporium . The chloroaniline/lignin conjugates were mineralized to carbon dioxide to the same extent as the control lignin. The free (ring-U- super(14)C)-4-chloroaniline and -3,4-dichloroaniline were mineralized to 35% and 50%, respectively. It is concluded that lignin incorporation, followed by fungal oxidation, represents a pathway for the complete removal of chloroanilines from the environment.
