Nonlinear rheological characteristics of single species bacterial biofilms

摘要

– Panels show representative pictures of single species biofilms spreading out radially from a 2 μL droplet on the agar plates for a period of 6 days. Scale bars for panels – are 5 mm. – Panels show the distribution of cells in scraped off biofilms as seen under a confocal microscope. The biofilm scrapings were taken from thick mat of biofilm that was formed on agar plates after a growth period of 3 days. Scale bars for panels – are 50 μm.
