Abstract
Most polycyclic aromatic hydrocarbons (PAH) are ubiquitous natural and/or anthropogenic pollutants that have adverse effects on the human health and the environment. Little is known about their potential effects on arbuscular mycorrhizal fungi (AMF). The study aims to study the impact of PAH on the lipid metabolism of Glomus sp. in relation with its development. Toxic effects of anthracene and benzo[a]pyrene (B[a]P)on the AMF was showed in presence of increasing concentrations of the PAH (140 and 280 mM) as compared to the control culture. The extraradical hyphae length and spore production were drastically restricted in the presence of PAH. The level of lipid peroxidation, as assessed by malondialdehyde (MDA) production, was markedly increased in the AMF under PAH treatment. In the other hand, whereas PAH did not affect the AMF total fatty acid contents (except for anthracene 140 mM), a significant reduction of Glomus sp. total sterol amounts was showed in presence of PAH. Taken together, our results suggest that the drastic decrease of Glomus sp. development observed could be explained by the toxicity of MDA accumulation and sterol metabolism perturbation.
