摘要：

Polycyclic aromatic hydrocarbons (PAHs) are environmental pollutants that represent a serious threat to the health of humans and ecosystems. The effects of plant root and artificial root exudates (ARE) on the biodegradation of phenanthrene (PHE) and their impact on soil bacterial community structure was the focus of this work using four treatments for 180 days. Treatments included; control treatment (CK), low concentration of ARE (AREL), high concentration of ARE (AREH), and planting Koelreuteria paniculata saplings (KOE). The diversity and composition of soil bacterial community were analyzed...
