The biofilm formation is delayed in nagC mutant of LF82 in a microfluidic system. a Biofilms of strain LF82, its isogenic mutant ΔnagC and complemented ΔnagC were formed in LB medium at 30 °C in the BioFlux 200 microfluidic system. NAG was supplemented at a concentration of 1 mM. A field of view representative of 3 independent replicates is shown for each test. Images were captured by phase contrast microcopy using a digital camera. b Quantification of biofilm formation was made using the “Analyze Particles” function of ImageJ and results show the percentage of the area covered by biofilm structures in images pictures. Statistical significance was calculated by one-way ANOVA with Dunnett’s multiple comparison test **P 0.01; ***P 0.001
