Morphology of bacterial spreading on gels

Abstract:
Capillary and friction forces experienced by bacteria on solid surfaces are so large they essentially prevent individual locomotion. It is quite remarkable that these microorganisms have evolved means to nevertheless collectively disseminate across surfaces. I will discuss what the resulting colony morphology ---such as the occasional reconnections in branched colonies--- can tell about these spreading mechanisms, some of which remain hypothetical, and what further measurements could complete the picture.
