Title:
CLEANING OF POLLUTED SOIL BY PLANT
Document Type and Number:
Japanese Patent JP2005253366
Kind Code:
A
Abstract:

To provide a method for cleaning soil polluted with harmful polycyclic aromatic compounds such as dioxins, by introducing a gene encoding carbazol 1,9a-dioxygenase decomposing the polycyclic aromatic compounds such as the dioxins, into a plant, cleaning the soil polluted with the harmful polycyclic aromatic compounds such as the dioxins, also recovering a plant body and making it harmless at a low cost without burning it.

This method for cleaning the polluted soil is provided by introducing a DNA encoding a terminal oxygenase (carAa) and ferredoxin (carAc), that is the DNA encoding the carbazol 1,9a-dioxygenase derived from Pseudomonas resinovorans CA10, into the plant, producing a transformed plant having an activity of carbazol 1,9a-dioxygenase of absorbing the polycyclic aromatic compounds such as the dioxins, and metabolizing/decomposing them, and planting such the transformed plants in the soil polluted with the harmful polycyclic aromatic compounds such as the dioxins, to clean the polluted soil.
