- Abstract
[Objective] To study the effects of plant/white rot fungi (WRF) inoculation on rhizosphere soil metabolome in root exudate of plants cultivated in PAH-contaminated soil. [Method] A pot experiment was conducted in greenhouse for bioremediation of PAH-contaminated soils and Salix viminalis L. was used as phytoremediation materials. Based on liquid chromatography-mass spectrometry (LC-MS) and metabolomics method, the test was focused on comparing the effect of inoculating Crucibulum laeve on metabolic profiling of rhizosphere PAH-contaminated soil of S. viminalis. [Result] Under POS and NEG mode, 881 and 823 compounds were detected and identified in metabolic profiling, respectively. Among them, 18 compounds were identified and assumed to be potential root exudates components. The component variety and content of rhizosphere metabolites were remarkably reduced by C. laeve inoculating, which including 16 root exudate components. [Conclusion] In this study, it is showed that inoculation with WRF can promote the uptake capability of roots to a broad spectrum of soil compounds. It is speculated that the response of plant roots to WRF stimulating leads to the improvement of PAHs phytoextraction capacity. This is of great significance for revealing the mechanism of plant/WRF combination remediation of PAH-contaminated soils.
