As several variations of in situ bioremediation and biorestoration are increasingly tested for clean-up of contaminated soils and river-bed sediments, it becomes more important to control bacterial transport through porous media. Motility of Escherichia coli K-12 cells was studied in a capillary tube with an inside diameter of 3 {micro}m, which is comparable to the size of the cells` body. The extreme restriction, imposed by the capillary on the bacterial motility, caused a series of phenomena such as cell aggregation, swimming as a cluster, and break-up of aggregates, which were observable for the first time, and which are reported.
