Long-term field experiments were performed to evaluate the phytotoxic properties of fungal
metabolites in oil-contaminated soil and to assess the impact of contamination on the
allelopathic activity of soil mycobiota. Two contrasting soils of Northwest Russia (sandy and
loamy podzols) exposed to oil contamination underwent changes in abundance and
allelopathic activities of soil fungi. Shifts within the microbial community caused by oil
contamination affected not only oil-decomposition rates but also ecotoxicity of contaminated …
