Effects of marine microbial biofilms on the biocide release rate from antifouling paints—A model-based analysis

Grafting of antibacterial polymers on stainless steel via surface‐initiated atom transfer radical polymerization for inhibiting biocorrosion by Desulfovibrio desulfuricans

“…Different strategies have been developed to address the growing need for combating biocorrosion (Akid et al, 2008;Al-Darbi et al, 2002;Cetin et al, 2007;Guezennec, 1994;Muthukumar et al, 2007;Sreekumari et al, 2005;Videla, 2002;Yebra et al, 2004). 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).…”

“…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).…”

Progress of marine biofouling and antifouling technologies

“…Moreover, TBT-SPC paints have high mechanical strength, high stability to oxidation, and short drying times [74]. The unavoidable formation of biofilm does not largely affect the net biocide leaching and binder reaction rates [79]. Therefore, in general, the TBT-SPC antifouling coating was widely applied in the shipping industry before it was banned.…”

Testing the impact of biofilms on the performance of marine antifouling coatings

“…There is a growing body of work looking at how biofi lms affect a coating's performance in terms of hydrodynamic drag (WHOI 1952;Watanabe et al 1969;Loeb et al 1984;Mihm et al 1988;Candries et al 2003;Valkirs et al 2003;Holm et al 2004;Schultz 2004) and biocide release rate (WHOI 1952;Mihm et al 1988;Valkirs et al 2003;Yebra et al 2006b;Howell 2007), although there has been very little work done in the last 20 years investigating how species diversity in biofi lms is affected by biocide concentrations from AF coatings (WHOI 1952;Dempsey 1981;Tang et al 1998;Boivin et al 2005;2006;Cassé et al 2006;Howell 2007), or by changes in shear stress (Beyenal et al 2002;Rickard et al 2004;Tsai 2005;Cassé et al 2006;Howell 2007). Species diversity could be important as new antifouling technologies based on micro-textured surfaces will need to address the community composition of biofi lms in order to be fully successful.…”

“…Yebra et al (2006b) completed a model based analysis of the effects of biofi lms on biocide release rates, but at this moment in time, as Yebra et al (2006a) note, many questions such as the AF effect of biocide saturated biofi lms and the rate of renewal of biofi lms, remain unanswered.…”
