A single substrate that discriminates between group[s of microorganisms on the basic of differences in their appearance due to different chemical reactions.
Differential medium.
A medium and a pressure differential
Both
Litmus milk contains several components such as; lactose (milk sugar) casein (milk protein) and Litmus ( Ph indicator) that can be metabolized. Thats why it is considered a good differential medium
Differential
The use of a medium that is both selective and differential can be justified in a few ways. They allowe the growth of organisms that can be of interest. The media can also be quite useful diagnostically in medical settings.
It is a SELECTIVE DIFFERENTIAL media used for the groth of Corynebacterium diphtheria.
EMB is an undefined selective/differential medium. It contains aniline dyes (methylene blue and eosin), which inhibit the growth of Gram-positive bacteria selecting for Gram-negative bacteria. EMB also contains lactose which makes the media differential based on an organisms ability to ferment lactose

Civil engineers use partial differential equations in many different situations. These include the following: heating and cooling; motion of a particle in a resisting medium; hanging cables; electric circuits; natural purification in a stream.
If you're talking about the differential gears, 75W-90 is something of a default for medium- and heavy duty trucks.
75W-90 is typically used as an "all around" gear oil for medium and heavy duty truck diffs.
