The laboratory demonstration exercises 

1. Structure/function analysis of P. aeruginosa biofilms in relation to quorum sensing activity and physiology. Display of AHL monitor systems in flow-chamber biofilms. Analysis of wild type and mutant strains including quorum sensing inhibition. Growth rate monitors and quantitative image analysis. Supervisor: Morten Hentzer

2. Flow cytometric analysis and cell sorting of biofilm-associated bacteria according to their physiological activity. FACS investigations and preparations of biofilm cells. Correlation between physiological activity and cell size. Isolation of differentially tagged cells. Investigations of live-dead stained cells from antibiotic treated biofilm. Supervisor: Claus Sternberg

3. Viscoelastic properties of biofilms. Supervisor: Paul Stoodley. Demonstration of the interaction of phagocytes with biofilms. Supervisor : Jeff Leid

4. Demonstration of proteomic analysis. Supervisor : Dave Davies. Microelectrodes for in situ measurements in biofilms. Supervisor: Michael Kuhl
