Abstract

The microbe-assisted remediation has been recognized as a potentially effective method for the removal and degradation of organic contaminants in soils. A study was conducted to examine the effects of inoculation with Mycobacteria M1 on phytoremediation of polycyclic aromatic hydrocarbons (PAHs) by ryegrass in contaminated soil. The results showed that Mycobacteria M1 had the ability to degrade PAHs. Ryegrass exudates can promote the degradation of PAHs by Mycobacteria M1. The group which added 80mg-L-1 ryegrass exudates reached the best promoting effect, the degradation rate of phenanthrene and pyrene reached 90.08% and 81.47%. The general trend in the degradation of phenanthrene was near- rhizosphere > rhizosphere > far-rhizosphere in rhizobox experiment. The results suggest that ryegrass-Mycobacteria M1 association can be used to renovate the contaminated soil by PAHs.
