Differential media, also known as indicator media, is a type of media (usually of a solid or semi-solid consistency) used to distinguish between bacterial cultures based on their biochemical. A differential stain is a stain that differentiates between gram-positive and gram-negative bacteria. Bacteria that stain purple are considered gram-positive and those that stain pink are considered gram-negative. 2. A simple stain is a stain that reacts with all microbes in and identical fashion. They are used to increase contrast. Differential media contain compounds that allow groups of microorganisms to be visually distinguished by the appearance of the colony or the surrounding media, usually on the basis of some biochemical difference between the two groups.

Other bacteria lose the stain and take on the subsequent methylene blue stain (blue). Thus, the acid‐fast bacteria appear bright red, while the nonacid‐fast bacteria appear blue when observed under oil‐immersion microscopy.. To confirm that these particles were indeed spores, they used differentialspore staining(to which spores respond in a particular way) and a heat-tolerance test to see how the particles responded to stress (spores are highly tolerant of physical and chemical stresses). cordis.
