MacConkey Agar by HiMedia is a selective and differential culture medium used for isolating and distinguishing Gram-negative enteric bacteria (like E. coli and Salmonella) from clinical, food, and water samples.
It uses bile salts and crystal violet to inhibit Gram-positive bacteria, and lactose with a neutral red indicator to differentiate lactose fermenters (pink) from non-fermenters (colorles

Mannitol from HiMedia is an acyclic sugar alcohol () used primarily as a microbiological ingredient for fermentation studies, selective isolation, and differential testing of microorganisms.
It is commonly used in Mannitol Salt Agar (M383/SMH118) and Mannitol Motility Nitrate Medium (M1320) to identify Staphylococcus aureus, distinguishing it by fermenting mannitol to produce yellow colonies

Yeast glucose refers to glucose acting as the preferred energy source, fermentation substrate, and primary signaling molecule for yeast (particularly Saccharomyces cerevisiae).

It drives alcoholic fermentation to produce ethanol and  and activates nutrient-sensing pathways (e.g., Rgt2/Snf3, AMPK, cAMP-PKA) regulating growth.

Cetrimide Agar Base is a selective, differential culture medium used primarily to isolate and identify Pseudomonas aeruginosa from clinical, pharmaceutical, and environmental samples

. It utilizes cetrimide (cetyltrimethylammonium bromide) to inhibit non-pseudomonad bacteria, while magnesium chloride and potassium sulfate stimulate pyocyanin production

*Potassium ferrocyanide, with the chemical formula K₄[Fe(CN)₆], is an inorganic compound also known as potassium hexacyanoferrate(II) or yellow prussiate of potash
*It forms lemon-yellow, monoclinic crystals and is commonly used as an anticaking agent, particularly in salt
* It also has applications in photography, as a pigment, and in analytical chemistry. 

Potato Dextrose Agar (PDA) is a common, nutrient-rich microbiological growth medium used to cultivate yeasts and molds

Composed of potato infusion, dextrose, and agar, it supports luxuriant fungal growth and is widely used for studying fungi in food/dairy products and inducing spore production
