Characterization of the Cell Surface and Cell Wall Chemistry of Drinking Water Bacteria by Combining XPS, FTIR Spectroscopy, Modeling, and Potentiometric Titrations

This paper, published in the journal ranked #1 in citations in the category of Materials Science (I.F. 4.187), presented for the first time a comprehensive chemical characterisation of the novel strain Aquabacterium commune, an autochthonous bacterium present in most European water distribution systems. The application of these findings to parameterising adhesion models, specifically through better understanding of forces, interaction energies of macromolecules and hydrophobicity of cells, were demonstrated. These findings were crucial to allow further investigations of microbial attachment and growth on surfaces (eg, pipe walls) that cause deterioration of water taste, harbouring of pathogens, and corrosion processes.
