  • Enhanced combination method for phytoremediation of petroleum contaminated soil by L. associated with the indigenous microorganisms
    Patent number: 9333382
    Abstract: A plant-microorganism combined method for phhytoremediation of organic contaminated soil; i.e., an ornamental plant (Impatiens balsamina L.)—microorganisms (petroleum hydrocarbon degrading mixed microbes) combined method for enhanced phytoremediation of petroleum contaminated soil is disclosed. The inoculated petroleum degrading mixed microbes can not only degrade contaminants in soil directly but also secretes chemical substances which are helpful to relieve the toxic effects on the Impatiens balsamina L. In return, the Impatiens balsamina L. releases photosynthesis products into the soil, so as to enhance microbial activity and quantity, and assist the microorganisms in degrading target contaminates more effectively and efficiently. Repeating the processes mentioned above is able to continuously reduce petroleum hydrocarbon contaminants in the soil until the residual content of contaminants meets the environmental safety standard.
