Abstract
Bacterial colonies can develop chiral morphology in which the colony c onsists of twisted branches, all with the same handedness. Microscopic observations of the chiral growth are presented. We propose that the observed (macroscopic) chirality results from the microscopic chiralit y of the flagella (via handedness in tumbling) together with orientati on interaction between the bacteria. The above assumptions are tested using a generalized version of the communicating walkers model.
