Rheoscopic effects: you see the whirls in this suspension of bacteria because turbulence aligns bacteria along different planes, and this changes the local light scattering. Video Credit: Mack Durham, Marcos, Justin Seymour, and Roman Stocker (MIT). Download video

These videos are short clips taken out of a series of 50 videos of a diatom chain’s lysis and the bacterial response.  Each video is 1 min long, at 60 fps, There are approximately 5 min between videos.  These representative clips demonstrate the bacterial response near the start and end of the diatom chain’s lysis.

Fluorescent Vibrio coralliilyticus in wells of the in situ chemotaxis assay. The first video shows negligible accumulation in a control well, where no chemotaxis is expected. The second video shows strong accumulation in response to marine broth as a chemoattractant.

Behavioral response of a “planktonic population” isolate and a “biofilm-forming” isolate in a temporally varying nutrient landscape. Behavioral responses of two recently speciated marine bacterial lineages are compared under switching chemical gradient. The upper two panels show cell swimming trajectories of V. cyclitrophicus1F111-pGFP (S) or V. cyclitrophicus ZF270-pGFP (L) isolates, as indicated in the panels. Shown is the vertical cross-section of the test channel (width = 1 mm). Model chemoattractant (serine) release into the test channel occurred from the left sidewall for the first 10 min and was then switched to the right sidewall. The lower two panels show the temporal dynamics of the chemoattractant concentration field in this experiment , modeled numerically. Each panel shows the concentration field within the vertical (xz) cross-section of the agarose layer and the test channel, as indicated. Colors represent the chemoattractant distribution.
