Agarose is sometimes used instead of agar to measure microorganism motility and mobility. Motile species will be able to migrate, albeit slowly, throughout the porous gel and infiltration rates can then be visualized.
Agarose is used as an alternative to agar for assessing microorganism motility and mobility. The ability of motile species to move through the porous gel allows for visualization of their migration patterns and calculation of infiltration rates.
