CIL:34522

The video is a representative movie of bacteria incubated in DMEM with BSA for 3 h on top of an array of pilars of stiffness 500 pN/micron. The video is real time and shows the behavior of one or two bacteria for 23 s after 3 h of incubation. The video relates to CIL: 34521 and 34523, which show bacteria incubated in different media. The pilars are 3 micron apart center to center. The video is DIC microscopy with the focus on the top of the pilars. See the transient pulls and the fact that the two bacteria are not as tightly connected to the pillars in this media. This video corresponds to Video 3 from PLoS Biol. 2008 Apr 15;6(4):e87.
