Plant-microbe joint interactions have a great potential to deal with the total petroleum hydrocarbon (TPH) during the effective remediation process. After four months plant cultivation, significant decreases of TPH concentration were observed in the rhizospheres of Scorzonera mongolica Maxim., Atriplex centralasiatica, and Limonium bicolor. Larger shoot and root biomass stimulated microbial biodegradation of TPH efficiently, higher average well color development (AWCD) was observed in the rhizosphere of these three plants compared with the non-rhizosphere soil, which was strongly associated with the higher TPH degradation rate. The data gathered from this study provides important information for utilization of the local plants for plant-microbe joint remediation of the crude oil contaminated soil. © 2011 Published by Elsevier Ltd.
