Myxococcus xanthus is a soil-inhabiting bacterium. In laboratories, it is typically cultured on agar plates made with dissolved yeast extract.
The video shows about 10 hours of the growth of a Myxococcus xanthus colony (frame rate: 1000x realtime). It was taken on an Olympus IX51 microscope using a PlanN 10x objective and a CCD camera (640 x 480 pixels).
When growing on nutritious gels, Myxococcus xanthus swarms in particular patterns. Individual cells pioneer outside well-defined colony edges. They are often trailed of stream-like cell groups. Eventually, the growing colony swamps into the preexplored areas, generally in patterns of circular waves.
Biophysics rules Fabian’s world. He’s been committing his scientific efforts to the endeavors nature takes us onto, when we look at the living world very closely. He’s been sharing this adventure with friends and colleagues in Heidelberg, Delft, Copenhagen and Princeton.
