“…Four different disinfecting agents were tested, with varying concentrations and contact times: glutaraldehyde (Sal vesen & Vadstein 1995, Dier ckens et al 2009), hydrogen peroxide, non-thermal plasma (NTP; Jacobs et al 2011, De Geyter & Morent 2012) and ozone, generated in dry air by a LAB2B ozone generator (Ozonia). All adopted protocols are listed in Table 2 (in the 'Results').…”

A thorough understanding of host−microbe interactions is crucial for more efficient disease management in the marine larviculture industry. As demonstrated in terrestrial animal research, gnotobiotic systems (involving animals cultured in germ-free conditions or inoculated with known microorganisms) are excellent tools to extend our understanding of the mechanisms involved in host−microbe interactions and allow the evaluation of new treatments for diseases. In this study, we introduce a germ-free European sea bass Dicentrarchus labrax larval model, independent of the continuous addition of antimicrobial agents. This model has an experimental set-up that allows addition of live feed to the larvae without compromising the germ-free status. This model will facilitate and render aquaculture research more effective in terms of mitigation fish larval diseases.KEY WORDS: Aquaculture · Gnotobiotic · Pathogen · Larvae Resale or republication not permitted without written consent of the publisherDis Aquat Org 117: [177][178][179][180][181][182][183][184][185] 2016 towards more strict regulations on the use of antibiotics in the aquaculture sector (Suba singhe et al. 2001, Romero et al. 2012, hence calling for alternative, sustainable methods to which the aquaculturist can resort for preventing and controlling disease outbreaks. Several environmentally friendly prophylactic disease treatments have been the focus of recent research, i.e. probiotics, prebiotics, vaccines, immunostimulants or antimicrobial peptides (Merrifield & Ringø 2014).A judicious and scientifically supported application of the abovementioned alternatives warrants a thorough testing of their efficacy and safety under standardized and controlled experimental conditions (Smith et al. 2003). However, the stochastic colonization of larvae by microorganisms may hinder the establishment of a reproducible experimental set-up by generating high inter-individual and inter-batch variability in the composition of the standing microbial community. Hence, from a microbiological point of view, iterating experimental conditions using conventional animals is almost impossible (Fjellheim et al. 2012). The development of test systems in which the researcher has complete control over the microbial community structure, by adopting a germ-free or gnotobiotic model, was revolutionary in this respect. As already demonstrated in multiple terrestrial animal studies, gnotobiotic models are an excellent tool to extend our understanding of (1) the nutritional requirements of host organisms, (2) host−microbe interactions and (3) host metabolic functions (Gordon & Pesti 1971, Wostmann 1996, Marques et al. 2005. Despite the significant increase in the use of fish as experimental animals during the last decades (Marques et al. 2005, Schaeck et al. 2013) and the stressed importance of raising aquatic organisms gnotobiotically (Bates et al. 2006), the current know-how of rearing gnotobiotic aquatic organisms is much more limited compared to the more traditional mammalian l...

For some applications of plastic materials, such as polystyrene, an important role is played by the wettability of the material. One of the methods of modifying material properties such as water contact angle is using nonthermal plasma. In this study, a radio-frequency atmospheric -pressure plasma jet source has been applied to the surface modification of a high-impact polystyrene film. The measurements show a dependence between the change in the water contact angle and the operating parameters of a nonequilibrium plasma treatment, such as the composition of the working gas, the flow rate, the distance from the plasma zone, and the discharge power.
