A mycological baseline study based on a multidisciplinary approach in a coastal area affected by contaminated torrent input

Mar Pollut Bull. 2017 Jun 15;119(1):446-453. doi: 10.1016/j.marpolbul.2017.03.070. Epub 2017 Apr 4.

Abstract

Fungi include a vast group of eukaryotic organisms able to colonise different natural, anthropised and extreme environments, including marine areas contaminated by metals. The present study aims to give a first multidisciplinary characterisation of marine bottom sediments contaminated by metals (Cd, Co, Cr, Cu, Ni, and Zn), originating in the water leakage from an abandoned Fe-Cu sulphide mine (Libiola, north-western Italy), and evaluate how the chemical and physical parameters of water and sediments may affect the benthic fungal communities. Our preliminary results showed the high mycodiversity of the marine sediments studied (13 genera and 23 species of marine fungi isolated), and the great physiological adaptability that this mycobiota evolved in reaction to the effects of the ecotoxic bottom sediment contamination, and associated changes in the seawater parameters.

Keywords: Coastal current; Marine-bottom sediments; Marine-derived fungi; Metal contamination.
