Abstract
Most polycyclic aromatic hydrocarbons (PAHs) 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). Thus, using monoxenic cultures, this work aims to study the impact of increasing concentrations (140 and 280 μM) of two PAHs [anthracene and benzo[a]pyrene (B[a]P)] on Glomus irregulare lipid content in relation with its development. Changes in the total lipids [fatty acids (FA), sterols, phospholipids (PL) and their associated FA (PLFA)] compositions and contents as well as [malondialdehyde (MDA)] production, of the AMF G. irregulare were examined. Direct toxic effects of both PAHs on the AMF were shown as compared to the control culture. The extraradical hyphae length and spore production were drastically restricted in the presence of PAHs. Significant decreases of the main membrane constituents, phosphatidylcholine (PC) and sterols (in particular 24-methycholesterol) were shown in G. irregulare grown under PAHs treatment. Moreover, PAHs exposure caused an oxidative stress in the AMF extraradical structures pointed out by an increase of the lipid peroxidation biomarker production (MDA). All the observed changes were less marked in presence of anthracene, which was found to be less toxic than B[a]P. Taken together, our results suggested that the drastic decrease of the AMF growth under PAHs pollution could partially be explained by depletions in sterols, PC and MDA accumulation.
