Communities of Fungi on Plates Coated with Antifouling Paint Modified by Nanoparticles

Abstract

In the Sevastopol Bay (Black Sea), in the autumn period of 2021, fungal complexes were studied on plexiglass plates painted with anti-fouling enamel Bioplast-52 (control) and coatings based on it modified with nanoparticles (NP) Zn-FeO, ZnO and Fe-SiO. 16 species of fungi belonging to seven genera, five families, five orders, three classes of the Ascomycota division have been identified. The species composition was dominated by representatives of the genera Aspergillus (7 species) and Alternaria (4 species). The total number of fungal species isolated on substrates varied from 3 (with ZnO NP) to 8 (Bioplast-52) and with Zn-FeO NP), and by exposure time – from 3 (fourteenth day) to 14 species (sixty-first day). There were no representatives of the genera Aspergillus and Alternaria on the coating modified with Fe-CuO NP; only species of the genus Aspergillus were found on the coating with ZnO NP, the smallest number and number of fungal species were found on these coatings. Fe-CuO and ZnO nanoparticles enhanced the antifouling properties of Bioplast-52 enamel.
