Synchronization with a periodic light source

The observation was made at a low intensity of the microscope illumination. The periodic illumination (sinusoidal) has a considerably higher intensity than the microscope illumination used for the exposure. As it couples only minimally into the beam path of the microscope, it is only slightly visible in the upper left. The video (60x time lapse) shows the transient to a state where the colonies move synchronously with the external illumination. This is directly visible in the synchronism between the colonies.
