Motility Testing is a test used to determine the motility of the microorganism based on the microscopic observation that can propel themselves through liquids. Motility Testing helps to understand the biochemical process of hydrogen sulfide production by bacteria. Motility is closely linked with chemotaxis i.e. the ability to orientate along certain chemical gradients. The capacity for self-propulsion or actual motility is present in various types of cells, but not true for all.
