Abstract

Clean-up of soils contaminated with organic pollutants is one of the most challenging tasks in environmental engineering. Bioremediation of contaminated soils is often constrained by poor nutrient status, lack of adequate microbial activity or low bioavailability of the pollutants. We have recently shown that biodegradation of organic pollutants is greatly enhanced in the rhizosphere. The use of plants for soil bioremediation is an economically and environmentally feasible way of remediating large areas of contaminated land. This proposal aims to increase the understanding of how rhizosphere interactions facilitate xenobiotic mineralisation. We will examine the role of soil history, root exudates and soil bacterial populations in rhizoremediation. Key rhizospheric factors involved in rhizoremediation will be identified. The information obtained will be used to optimise rhizoremediation strategies in the field.
