how do we determine motility
Motility. In our lab, the preferred way to determine motility is to use the semi-solid medium which contains the indicator tetrazolium chloride (TTC). Instructions on how to perform the test are here. Reading a motility test is easy when you know what you're looking for. When you're ready to read your inoculated tube, carefully hold it up to the light. It helps to hold an uninoculated tube next to it for comparison.
MOTILITY TESTS. There are a variety of ways to determine motility of a bacteriumâbiochemical tests as well as. microscopic analysis. Microscopy is the most accurate way to determine motility, assuming. that you have a fresh culture of bacteria. Not only can motility be identified, but also the. organization and number of flagella.
