Shewanella algae B516 inhibits swarming motility of Vibrio alginolyticus by producing avaroferrin. A) Plate based swarming assay shows a zone of inhibition around the colony of S. algae. B) Cell motion activity given by per-pixel normalized temporal variance of time-lapse image series whereby high temporal variance means high motion activity and the frequency displays the fraction of pixels at a given motion activity. Bacteria in the thin cell layer in the inhibition zone S1 displayed highly reduced motility compared to zone S2 near the colony of V. alginolyticus. Inset: motion activities of the corresponding zones (C1 and C2) in the non-inhibited control (blank) show no distance dependence. Error bars give the standard error of the mean. C) Crystal structure of avaroferrin at 0.84 Å resolution and D) structural drawing of avaroferrin.
