“…The prevailing EL character of bacteria-solid interactions is enhanced by low ionic strength (10 mM), which increases the distance (Debye length) over which significant charge interactions can occur (28). Given the opposite charge of bacteria and APTES glass at pH 3 and 7 it is no surprise that the APTES glass has already been found to be the most attractive surface for microbial colonization in dilute electrolytes (19,29). The prediction of energetically favourable interactions of bacteria with BS and PTES glass at pH 3, as confirmed by adhesion tests, was also based on attractive EL forces.…”

Developments in filling technologies have led to a reduction in oxygen content in beer, thus producing an anaerobic environment suitable for the growth of anaerobic beer‐spoiling microorganisms. Anaerobic bacteria survive well in a biofilm that provides protection against environmental stress factors. The initial step in biofilm formation is adhesion of cells to a solid surface. Therefore the purpose of this research was to study theoretically and experimentally adhesion of strains of Megasphaera cerevisiae to different solid surfaces with properties covering a wide range of materials used in breweries. Experimental characterization of surface properties was used to model surface interactions, resulting in a quantitative prediction of cell adhesion. The colloidal model predictions were then compared with adhesion tests. As revealed experimentally, the most significant adhesion occurred to 3‐aminopropyltriethoxysilane‐modified glass (substitute for stainless steel) at pH 3–7. According to physicochemical interaction models, under these conditions interactions were influenced mostly by electrostatic attractions between surfaces. At pH 3, experimental data, supported by theoretical predictions, showed significant bacterial adhesion to borosilicate glass (a hydrophilic surface) and propyltriethoxysilane‐modified glass (a hydrophobic surface). Conversely, the least adhesion of M. cerevisiae was both predicted and observed at pH 10, since at an alkaline pH, electrostatic repulsion between surfaces predominates. Since adhesion can be expected mainly at an acidic pH, prevention should be based on the use of alkaline cleaning agents and/or alkaline rinse water at the end of the cleaning procedure. An elevated risk of adhesion to stainless steel was also identified, allowing appropriate measures to be taken. Copyright © 2017 The Institute of Brewing & Distilling

“…Moreover, Chlorella adhered to the surface of PDA-Ag-HF/GSs, but the growth of the Chlorella was inhibited. This was mainly due to the ability of Chlorella to generate adhesion proteins that adhered to the surface of GSs [33,34]. However, much Ag + was released on the surface of the Ag-modified surface and Ag + could be bound to the surface to cause changes in the cell membrane [35].…”

Filtering media is anything placed in a filter that changes the quality of water flowing through it. With the variety of media available, proper selection of filter media is of great importance for filter performance. Recycled glass is evaluated as an alternative to silica sand in media filters and is an effective medium with the advantages of lower cost than silica sand, more environmental friendliness as it is a recycled product, and ease to pulverize into different sizes for specific design requirements. However, the filtration efficiency of regenerated recycled glass is limited by the formation of biofilms on its surfaces due to the large number of microorganisms such as bacteria and algae existing in the water. In this study, hydrofluoric (HF) acid etched glass spheres (GSs) modified with polydopamine (PDA) and silver nanoparticles (PDA-Ag-HF/GSs) were fabricated on the surface of soda-lime GSs by HF etching, crystal in situ growth, and PDA coating. HF etching and the modification of PDA coating imparted good hydrophilicity to PDA-Ag-HF/GSs. The modification of the silver coating also rendered PDA-Ag-HF/GSs excellent antibacterial properties and reduced Chlorella adhesion, and inhibited microorganism growth ability by releasing Ag +. The catechol functional group on the PDA coating could regulate the Ag + release by chelation. Good antibacterial properties, anti-algae adhesion, and controlled release of Ag + indicate that PDA-Ag-HF/GS coating can effectively inhibit the formation of biofilm on the surface of the material, providing a new strategy for the formation of anti-biofilm.

“…Physicochemical approaches, such as the XDLVO (extended Derjaguin-Landau-Verwey-Overbeek) theory, can show the interplay of all non-covalent LW, EI and AB forces, and as such they are considered to be very helpful tools in predicting (un)favorable conditions for microbial cell adhesion (Hwang et al, 2012;Kurec & Branyik 2011;Sirmerova et al, 2013). Illustration of modeling using the XDLVO theory, i.e.…”

The majority of algal cells can interact with a wide range of nano- and microparticles. Upon interaction the modified cells usually maintain their viability and the presence of foreign material on their surfaces or in protoplasm can provide additional functionalities. Magnetic modification and labeling of microalgal biomass ensures a wide spectrum of biotechnological, bioanalytical and environmental applications. Different aspects of microalgal cell magnetic modification are covered in the review, followed by successful applications of magnetic algae. Modified cells can be employed during their harvesting and removal, applied in toxicity microscreening devices and also as efficient adsorbents of different types of xenobiotics.
