Ans.) For pathogenic bacteria, there are safer techniques to determine the bacterial motality. SIM media is one of the media commonly used to demonstrate the motality. Sulfide-Indole-Motility (SIM) medium - It is a differential medium that tests three distinct parameters, Sulfur Reduction, Indole Production and Motility. This media has a delicate consistency that permits motile microorganisms to move promptly through them bringing on darkness. The non-motile microbes will just develop in the delicate agar tube and just the range where they are vaccinated. Be that as it may, on account of motile microscopic organisms, they will develop along the range of cut and will likewise swim out far from the wounded zone. Subsequently, a negative result is recognized by development in a particular zone specifically along the wound. A positive result is shown by diffuse or shady development generally at the top and base of the wound. Solution Ans.)
