Predatory bacterial swarm uses rippling motion to reach prey
Date:10/29/2008

s in the amount of available prey and both mutant strains were deficient in predation.

"Our study really connects the stimulus to the behavioral response through this molecular machinery," Kirby said.

In addition the potential medical application of M. xanthus to destroy harmful bacteria, what Kirby learns about the molecular mechanisms used by the bacterium may also provide insights into the workings of a rarer, but potentially useful, bacterial cousin. The related bacterium, Anaeromyxobacter dehalogenans, has been found at superfund sites and it can transform soluble uranium, which can leach into the water supply, into insoluble uranium, which still is radioactive, but is stable and trapped in the soil where it can be more safely stored until the radioactivity decays.
