“…Although rubber is inert in the marine environment, some research has focused on leaching of heavy metals and organic compounds from rubber to surrounding water. Heavy-metal leaching in seawater could be effective in preventing the colonization of the substrate by fouling organisms, as reported by JELIĆ-MRČELIĆ (2006) in tests with heavy-metal leaching antifouling (AF) coatings. Zinc, as a major toxicant that rubber leaches into the water environment, was identifi ed by COLLINS et al (1995) andGUALTIERI et al (2005), but according to their study, the amount of zinc being released in that way does not have any signifi cant effect on most marine organisms.…”

-The settling of diatoms as fouling organisms on a certain substrate is greatly infl uenced by substrate characteristics and the preferences of a diatom community and diatom species. A distinction among substrates can be made by analysing the specifi c abundance and composition of diatoms on different substrates. In this study, 11 different artificial substrates were exposed to a marine environment for a period of 30 days. Abundance and taxonomic composition of periphytic diatoms was determined on each of the substrates and on shoots of the marine seagrass Posidonia oceanica. The aim was to compare diatom community structure on different newly colonized surfaces. On all surfaces examined, periphytic diatoms were the pioneering organisms with differences in quantitative and qualitative composition on the different substrates. Taxonomic analysis of diatom communities on the substrates examined revealed 41 diatom taxa, with the dominant genera Cylindrotheca, Amphora, Nitzschia, Cocconeis and Navicula. Given that all the examined artifi cial substrates were solid materials, differences in the abundance and species composition of diatoms found between the materials point to the substrates' physical and chemical characteristics as a major infl uence on the fi nal settling of diatoms. Knowledge from investigating the settlement of fouling organisms on anthropogenic substrates can have future use in management of waste materials that end up in the marine environment.

“…These studies suggest that the type of biocide and environmental conditions affected the composition of the bacterial and diatom communities. Moreover, only a few investigations have been reported on the long-term (>6 months) microbial fouling on biocidal coatings (Igic 1988;Jelic-Mrcelic et al 2006). None of these have used molecular methods for microbial identification.…”

Long-term microfouling on commercial biocidal fouling control coatings

et al. 2014

The current study investigated the microbial community composition of the biofilms that developed on 11 commercial biocidal coatings, including examples of the three main historic types, namely self-polishing copolymer (SPC), self-polishing hybrid (SPH) and controlled depletion polymer (CDP), after immersion in the sea for one year. The total wet weight of the biofilm and the total bacterial density were significantly influenced by all coatings. Pyrosequencing of 16S rRNA genes revealed distinct bacterial community structures on the different types of coatings. Flavobacteria accounted for the dissimilarity between communities developed on the control and SPC (16%) and the control and SPH coatings (17%), while Alphaproteobacteria contributed to 14% of the dissimilarity between the control and CDP coatings. The lowest number of operational taxonomic units was found on Intersmooth 100, while the lowest biomass and density of bacteria was detected on other SPC coatings. The experiments demonstrated that the nature and quantity of biofilm present differed from coating to coating with clear differences between copper-free and copper-based biocidal coatings.

“…Biocidal treatment is a conventional approach for mitigating the problem of biofouling and biocorrosion in closed systems, such as potable water distribution systems (Mohanan et al, 2005;Videla, 2002). Alternatively, protective antifouling coatings, such as tributyltin (TBT)-based paints, are used extensively in seawater environments, despite concerns for their toxicity, to combat biofouling and biocorrosion of metallic materials (Jelic-Mrcelic et al, 2006;Yebra et al, 2004). Although cathodic protection has been reported to effectively inhibit biocorrosion of SS by aerobic bacteria (Guezennec, 1994;Miyanaga et al, 2007), it has been found to have no effect on the adhesion of anaerobic bacteria, and is thus unable to prevent the initiation of pitting corrosion by SRB (de Mele et al, 1995).…”

To enhance the biocorrosion resistance of stainless steel (SS) and to impart its surface with bactericidal function for inhibiting bacterial adhesion and biofilm formation, well-defined functional polymer brushes were grafted via surface-initiated atom transfer radical polymerization (ATRP) from SS substrates. The trichlorosilane coupling agent, containing the alkyl halide ATRP initiator, was first immobilized on the hydroxylated SS (SS-OH) substrates for surface-initiated ATRP of (2-dimethylamino)ethyl methacrylate (DMAEMA). The tertiary amino groups of covalently immobilized DMAEMA polymer or P(DMAEMA), brushes on the SS substrates were quaternized with benzyl halide to produce the biocidal functionality. Alternatively, covalent coupling of viologen moieties to the tertiary amino groups of P(DMAEMA) brushes on the SS surface resulted in an increase in surface concentration of quaternary ammonium groups, accompanied by substantially enhanced antibacterial and anticorrosion capabilities against Desulfovibrio desulfuricans in anaerobic seawater, as revealed by antibacterial assay and electrochemical studies. With the inherent advantages of high corrosion resistance of SS, and the good antibacterial and anticorrosion capabilities of the viologen-quaternized P(DMAEMA) brushes, the functionalized SS is potentially useful in harsh seawater environments and for desalination plants.
