Objective:

The purpose of this study was to investigate and establish a plant-assisted (phytoremediation) system with the aid of plant biotechnology to enhance the uptake, accumulation and degradation of organic (halogenated) and inorganic (heavy metals) contaminants of Bayou d'Inde tributary and other sites, similar in nature.

Approach:

In this research, the development of a plant cell and tissue culture system in order to select plant cells with higher tolerance to selected heavy metals and organic compound(s) from most successful plant species established in the Bayou d'Inde tributary was performed. Follow up activities included the investigation of the possible extent of transport or uptake, accumulation and biodegradation of selected heavy metals and halogenated organic compound(s) by tolerant and sensitive cells, and regenerated plants.
