Soft Matter Seminar: Bacterial surface motility and biofilm formation strategies in a motile and non-motile bacterium
Dr. Andrew S. Utada, Ph. D. Faculty of Life and Environmental Sciences, University of Tsukuba
Bacteria in the environment exist either as individual, planktonic cells, or as members of surface-adhered 3D communities, encased in a slimy extracellular matrix, called biofilms. The biofilm lifestyle is fundamental to bacterial ecology and it begins with the initial encounter a bacterium has with a surface. However, different bacteria engage and colonize surfaces differently, depending on their specific ecological niche. We utilize time-lapse microscopy, single-cell tracking algorithms, and microfluidics to control the local environment, image, and analyze the first stages of biofilm formation and to compare the strategies of motile and non-motile bacteria.
