“…It is believed that EPS production is essential in facilitating the initial stages of bacterial attachment to various surfaces (8,13). Our recent studies on bacterial attachment to nanosmooth glass surfaces and to poly(tert-butyl methacrylate) (P(tBMA)) polymeric surfaces were in agreement with this concept: Enhanced bacterial attachment was accompanied by elevated levels of secreted extracellular polymeric materials (9,10,13). In this study the shift in production of low amounts of EPS might be also due to the low carbon/nitrogen ratio as it was previously reported that EPS production is strongly dependent on the carbon/nitrogen ratio of the nutrient medium (5).…”

Plastic debris causes extensive damage to the marine environment, largely due to its ability to resist degradation. Attachment on plastic surfaces is a key initiation process for their degradation. The tendency of environmental marine bacteria to adhere to poly(ethylene terephthalate) (PET) plastic surfaces as a model material was investigated. It was found that the overall number of heterotrophic bacteria in a sample of sea water taken from St. Kilda Beach, Melbourne, Australia, was significantly reduced after six months from 4.2-4.7×10 3 cfu mL −1 to below detectable levels on both full-strength and oligotrophic marine agar plates. The extinction of oligotrophs after six months was detected in all samples. In contrast, the overall bacterial number recovered on full strength marine agar from the sample flasks with PET did not dramatically reduce. Heterotrophic bacteria recovered on full-strength marine agar plates six months after the commencement of the experiment were found to have suitable metabolic activity to survive in sea water while attaching to the PET plastic surface followed by the commencement of biofilm formation.

“…Many studies have shown that the surface roughness of biomaterials strongly influences the degree of bacterial attachment to surfaces (44,59,89). For instance, streptococcal adhesion was surface roughness sensitive and increased as the roughness of composite surfaces increased from 20 nm to 150 nm and 350 nm (58).…”

c Biofilm formation on implantable medical devices is a major impediment to the treatment of nosocomial infections and promotes local progressive tissue destruction. Staphylococcus epidermidis infections are the leading cause of biofilm formation on indwelling devices. Bacteria in biofilms are highly resistant to antibiotic treatment, which in combination with the increasing prevalence of antibiotic resistance among human pathogens further complicates treatment of biofilm-related device infections. We have developed a novel plasma coating technology. Trimethylsilane (TMS) was used as a monomer to coat the surfaces of 316L stainless steel and grade 5 titanium alloy, which are widely used in implantable medical devices. The results of biofilm assays demonstrated that this TMS coating markedly decreased S. epidermidis biofilm formation by inhibiting the attachment of bacterial cells to the TMS-coated surfaces during the early phase of biofilm development. We also discovered that bacterial cells on the TMS-coated surfaces were more susceptible to antibiotic treatment than their counterparts in biofilms on uncoated surfaces. These findings suggested that TMS coating could result in a surface that is resistant to biofilm development and also in a bacterial community that is more sensitive to antibiotic therapy than typical biofilms.

“…Several studies have reported [36][37][38] AFM imaging of bacterial cells using artificial immobilization procedures of the cells to a surface or dried samples where the effect of dehydration can be observed on the bacteria. In this study, the natural adhesion of X. fastidiosa was utilized to observe the early biofilm stages without additional immobilization procedures.…”

“…S1). Several authors [37][38][39] attribute these additional deposits to EPS, which contributes to irreversible adhesion and biofilm protection. Although aggregated cells are not usually considered to pioneer biofilm formation [40], their role should not be neglected once irreversible adhesion takes place.…”

Biofilms are complex microbial communities with important biological functions including enhanced resistance against external factors like antimicrobial agents. The formation of a biofilm is known to be strongly dependent on substrate properties including hydrophobicity/hydrophilicity, structure, and roughness. The adsorption of (macro)molecules on the substrate, also known as conditioning film, changes the physicochemical properties of the surface and affects the bacterial adhesion. In this study, we investigate the physicochemical changes caused by Periwinkle wilt (PW) culture medium conditioning film formation on different surfaces (glass and silicon) and their effect on X. fastidiosa biofilm formation. Contact angle measurements have shown that the film formation decreases the surface hydrophilicity degree of both glass and silicon after few hours. Atomic force microscopy (AFM) images show the glass surface roughness is drastically reduced with conditioning film formation. First-layer X. fastidiosa biofilm on glass was observed in the AFM liquid cell after a period of time similar to that determined for the hydrophilicity changes. In addition, attenuation total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy supports the AFM observation, since the PW absorption spectra increases with time showing a stronger contribution from the phosphate groups. Although hydrophobic and rough surfaces are commonly considered to increase bacteria cell attachment, our results suggest that these properties are not as important as the surface functional groups resulting from PW conditioning film formation for X. fastidiosa adhesion and biofilm development.
