Motility Tests
Motility can be checked by microscopy using the hanging drop technique.  Motility media includes SIM agar (see Indole test) and TTC motility media which contains a tetrazolium salt which changes color where bacterial growth is located.  In both cases growth along the inoculation line only indicates non-motile organisms while diffuse or confluent growth through the tube indicates motility.
