Der Vortrag stellt die Arbeiten der BAM in der Initiative QI-Digital vor, in deren Rahmen Lösungen für eine moderne und digitale Qualitätsinfrastruktur entwickelt werden. Schwerpunkt liegt auf dem zentralen Werkzeug Quality-X sowie dem Pilotprojekt "Moderne Qualitätssicherung in der Additiven Fertigung".
Outer membrane lipopolysaccharides (LPS) play a crucial role in determining attachment behavior and pathogenicity of bacteria. The aim of this study was to develop a simple procedure for anchoring bacterial lipopolysaccharides to polystyrene (PS) microparticles as a model system for in situ attachment studies. By using a swellcapture methodology, commercially available LPS of Pseudomonas aeruginosa (strain ATCC 27316 serotype 10.22) was anchored onto PS microparticles in a proof-of-concept study. A detailed chemical and morphological characterization has proven the success of LPS incorporation. It was shown that the coverage and structure of the LPS film was concentration dependent. The procedure can easily be adapted to LPS of other bacterial strains to generate a synthetic model toolkit for attachment studies.
