Combined application of resveratrol and a ryegrass endophyte in PAH-contaminated soil remediation and its impact on soil microbial communities.

ABSTRACT: The unique capacity of certain plant endophytes to degrade organic pollutants has garnered considerable interest in recent years. However, it remains uncertain whether endophytes can maintain high degradation activity after in vitro culture and whether they can be used directly in the remediation of contaminated soils. This study reveals that resveratrol, a plant secondary metabolite, selectively boosts the degradation of polycyclic aromatic hydrocarbons (PAHs) by endophytic Methylobacterium extorquens C1 (C1) in vitro, while exerting negligible effects on the activity of indigenous soil bacteria. For the first time, a combined application of C1 and resveratrol was employed in the remediation of polycyclic aromatic hydrocarbon (PAH)-contaminated soil. The findings indi
