Santiago de Compostela, October 8th-11th (2019). Cylindrospermopsin (CYN) and Microcystin‐LR (MC‐LR) are biotoxins produced by cyanobacteria species that, as consequence of human‐induced environmental changes i.e. increase of temperature due to climate change and the eutrophication of waters, proliferate together with an increase in the presence of the associated cyanotoxins. Both toxins are usually found in the aquatic environment, filter feeding organisms such as mussels are exposed continuously an at such quantity that may be the cause of metabolic alterations. Analytical pyrolysis (Py‐GC/MS) was used to evaluate compositional changes in M. galloprovincialis after exposure for 14 days to cyanotoxins of Chrysosporum ovalisporum (CYN) (0.785 μg mL‐1), Microcystis aeruginosa (MC‐LR) (2.3 x 10‐3 μg mL‐1) and a combination of both toxins (CYN + MC‐LR). A group of mussels not exposed to the toxins was also included as control. Pyrolysis of lyophilized mussel flesh produced complex chromatograms (100 different compounds) but very similar between treatments. Major groups found were N compounds (pyridine, N‐alkyl molecules) (18% ± 1.5) and peptide/protein derived (18% ± 2.4) that include alkyl indols and diketopiperazines (DKPs) as pyrolysis product from amino acid condensation, series of medium chain length (C14‐C22) saturated, mono and polyunsaturated fatty acids (45% ± 5.0), sterols (8% ± 0.6) and aromatics with undetermined origin (9% ± 1.01). Chemometric treatment of the chromatographic data (variable reduction, PCA and hierarchical cluster analyses) allow us to discriminate between the different mussel populations exposed to cyanotoxins. The results are discussed in terms of the possible effects exerted by the biotoxins in mussel composition and possible metabolic pathways affected.
