Investigation on the proliferation of Gram negative bacterial cells onto sol-gel carriers

International audienceThis work is related to the synthesis and characterization of new hybrid sol-gel materials. Several carriers based on poly (N-acryloylglycine) (NAGly) composed of poly (ethylene glycol) dimethacrylate (PEGDM) were prepared. The effectiveness of biofilms formation of bacterial strains Escherichia coli and Pseudomonas fluorescents on the matrices was investigated by biochemical methods. Two types of hybrid gels were synthesized based on PEGDM, 2-hydroxyethyl acrylate (HEA) and N-acryloxysuccinimide ester (NAS) with incorporation of inorganic precursors. The rheological properties of the gels and formed biofilms were investigated by quartz crystal microbalance (qCM). The experimental results demonstrated that the obtained matrices are appropriate for biofilms formatio
