“…Gomes et al (2014b) studied the effect of different materials (glass, stainless steel, silicone and polyvinyl chloride) on E. coli initial adhesion and biofilm formation. These authors, as well as others (Fonseca et al, 2001;Kochkodan et al, 2008;Treter et al, 2014), also found a correlation between cell attachment and surface hydrophobicity. In this work, this tendency was observed on average for 83% of the obtained results.…”

Abstract:In the food industry, biofilm formation in pipes, equipment and cooling systems increases maintenance costs, decreases operational efficiencies and is a source of contamination.Shear stress, nutrient load and surface material are important variables affecting the biofilm onset in industry. In this work, the combined impacts of these variables were assessed using three different materials (glass, copper and stainless steel), two nutrient loads (high and low nutrient medium) and two hydrodynamic conditions (static and dynamic). Initial adhesion and biofilm formation were studied in microplates usingEscherichia coli as a model organism.Surface material was the factor with the strongest impact and adhesion/biofilm formation were correlated with surface hydrophobicity. However, the impact of this variable was dependent on the nutrient load and imposed shear stress. It was also found that, for the majority of the situations tested, initial attachment performance is a good predictor of biofilm formation behaviour and that the effects observed during attachment are amplified during biofilm maturation. Since shear stress is a major determinant in cell adhesion, the results of this study may find application in industrial systems operating at flow rates between 0.001 and 600 m 3 h -1 depending on tube material and diameter.

“…[63][64][65] The efficacies of these methods have been extensively investigated in in vitro conditions with the reduction in surface bacterial adhesion reported as being between 60 and 99%. 62,[66][67][68][69][70][71][72][73][74] For example, the adhesion of S. epidermidis on a titanium surface with bioactive water-soluble copolymers bearing sulfonate functions has been reported to be reduced by 68% compared to that for the untreated surface, 66 while modification of PS with hyaluronic acid and alginic acid yielded over 99% reduction in the adhesion of S. epidermidis compared to that for the untreated surface. 75 The use of zwitterions and PAs for the reduction of bacterial adhesion is a relatively new strategy, and there are fewer reports on their efficacy.…”

In order to improve their bacterial antifouling property, silicone surfaces were functionalized through the plasma polymerization (PP) technique using diethyl phosphite as the precursor. The functionalized surfaces were characterized using contact angle measurements, contact angle titration, Fourier transform infrared-attenuated total reflection spectroscopy and in vitro cytotoxicity assay. The amount of non-specific protein adsorption and the conformational changes of surface-adsorbed proteins were investigated. Antifouling properties of the surfaces were evaluated in vitro and in vivo. PP functionalization generated a hydrophilic and amphoteric surface with a very good protein and bacterial antifouling property and caused less conformational changes on the secondary structure of surface-adsorbed proteins. In in vivo conditions, no slime layer was formed around bacteria that adhered on the PPfunctionalized surface. It is concluded that the amphoteric nature of the PP-functionalized surface is the reason for the good antifouling property.

“…Cationic dicephalic surfactants differing in hydrocarbon chain length were shown to have an antibacterial effect on planktonic Staphylococcus epidermidis and cause a reduction in its biofilm formation on glass and stainless steel . Pluronic F127 (Poloxamer 407) was reported to resist multiple washes when impregnated into a hydrophobic surface and subsequently could reduce S. epidermidis attachment and biofilm formation …”

Surfactants are widely used as detergents, emulsifiers, wetting agents, foaming agents, and dispersants in both the food and oil industry. Their use in a clinical setting is also common, particularly in wound care. Complicated or chronic wounds show clinical signs of delayed healing, persistent inflammation, and the production of non-viable tissue. These types of wounds also present challenges such as infection and potentially house antimicrobial-tolerant biofilms. The use of wound cleansers to aid cleaning and debridement of the wound is essential. A large proportion of skin and wound cleansers contain surfactants but there is only a small amount of data that shows the effectiveness of them in the enhancement of wound closure. This review paper aims to explore the available literature surrounding the use and mode of action of surfactants in wound healing, in particular Poloxamer 188 (Pluronic F-68) and Poloxamer 407 (Pluronic F-127), and also uncover the potential mechanisms behind the enhancement of wound healing and comparison to other surfactants used in wound care. Furthermore, the presence of a microbial biofilm in the wound is a significant factor in delayed wound healing. Therefore, the effect of clinically used surfactants on biofilms will be discussed, with emphasis on poloxamer-based surfactants.
