“…As a typical rodlike Gramnegative bacteria, E. coli is widely distributed in marine environment and causes serious biofouling, so it is often used to evaluate the contamination resistance of materials. 26,40 Navicula exigua belongs to diatoms which has a strong adaptability and can attach on metal surfaces before macrofouling organisms. So E. coli and Navicula exigua are generally thought to be involved in the early stages of biofouling and play a dominant role in biofouling.…”

Becauseof the high strength-to-weight ratio and excellent corrosion resistance, titanium alloys are widely applied in marine industries. However, titanium alloys suffer from serious biofouling problems for their good biocompatibility. Slippery lubricant-infused porous surface (SLIPS) exerts a positive effect on inhibiting the attachment of marine microorganism. In this work, SLIPS was fabricated on TC4 (Ti-6Al-4V) alloys through anodic oxidation, 1H,1H,2H,2H,-perfluorooctyltriethoxysilane (POTS) modification and polyperfluoromethyl isopropyl ether (PFPE) infusion to improve the antifouling property of TC4 alloys. The antifouling effect of all coatings was investigated and compared to obtain the antifouling mechanism of SLIPS through recording the settlement of E. coli and Navicula exigua. The results showed that three different kinds of nanostructures were fabricated on TC4 alloys by anodic oxidation. The nanotubes with the largest internal volumes were conducive to storing more lubricant and firmly holding the lubricant for a long time. The SLIPS could effectively suppress the attachment of E. coli and Navicula exigua on account of the ultraslippery behavior of lubricant layer. In particular, the SLIPS-30 V fabricated by the largest nanotubes displayed a long-term anti-adhesion behavior. Besides, the SLIPS could improve the corrosion resistance of TC4 alloys. Hence, such SLIPS with excellent fouling-resistant and anti-corrosion performance could be applied to titanium alloys or other alloys to expand their application in the marine area.

“…Moreover, the lowest and the highest adhesion values were obtained when the surface was treated by the semi-skimmed milk and skimmed milk, respectively, showing that adhesion is affected by fat content (Hamadi et al, 2014). Recently, it was found that adsorption of alginate and albumin onto aluminum coatings inhibited Escherichia coli adhesion by altering the surface hydrophobicity (He et al, 2015). This conditioning layer also enhanced the anti-corrosion performance of the coatings (He et al, 2015).…”

“…Although one might think that adsorbed cell components and related molecules can automatically enhance cell retention and reduce surface hygiene, it is known from several studies that proteins such as bovine serum albumin (BSA), gelatin, fibrinogen and pepsin adsorbed to surfaces may inhibit bacterial attachment [11],[12],[13]. Recently, it has been shown that surface preconditioning has potential to prevent bacterial adhesion to processing surfaces [14]–[18]. In order to elucidate about the process of bacterial contamination in dairy industry, Dat et al [16] investigated the influence of surface conditioning with dairy by-products such as skimmed milk, buttermilk and butter serum (which possess different compositions) on the bacterial attachment behavior.…”

Surface conditioning with <em>Escherichia coli</em> cell wall components can reduce biofilm formation by decreasing initial adhesion

Bacterial adhesion and biofilm formation on food processing surfaces pose major risks to human health. Non-efficient cleaning of equipment surfaces and piping can act as a conditioning layer that affects the development of a new biofilm post-disinfection. We have previously shown that surface conditioning with cell extracts could reduce biofilm formation. In the present work, we hypothesized that E. coli cell wall components could be implicated in this phenomena and therefore mannose, myristic acid and palmitic acid were tested as conditioning agents. To evaluate the effect of surface conditioning and flow topology on biofilm formation, assays were performed in agitated 96-well microtiter plates and in a parallel plate flow chamber (PPFC), both operated at the same average wall shear stress (0.07 Pa) as determined by computational fluid dynamics (CFD). It was observed that when the 96-well microtiter plate and the PPFC were used to form biofilms at the same shear stress, similar results were obtained. This shows that the referred hydrodynamic feature may be a good scale-up parameter from high-throughput platforms to larger scale flow cell systems as the PPFC used in this study. Mannose did not have any effect on E. coli biofilm formation, but myristic and palmitic acid inhibited biofilm development by decreasing cell adhesion (in about 50%). These results support the idea that in food processing equipment where biofilm formation is not critical below a certain threshold, bacterial lysis and adsorption of cell components to the surface may reduce biofilm buildup and extend the operational time.
