Preparation of agar medium. 1. Prepare MHA from the dehydrated medium according to the manufacturer's. instructions. Media should be prepared using distilled water or deionized water. Mueller Hinton Agar media contains Beef Extract, Acid Hydrolysate of Casein, Starch and Agar. Each lab should verify the quality and functionality of each batch of prepared media by testing known strains of organisms against each antimicrobial compound being used as the 70 -day expiration date Most microorganisms living in the environment have yet to be cultured, owing at least in part to their slow and poor propagation properties and susceptibility to oxidative stress. Our previous studies demonstrated that a simple modification in the preparation of agar media, i.e., autoclaving the pho Selective agar media are great tools for food microbiologists. Their shortcomings became apparent, however, when food microbiologists noted that some selective agents would not recover sublethally injured bacteria that otherwise might recover in the food. Frank Bustaand Jezeski, in 1963, testing the Culture media preparation is one of the routine tasks common to many microbiology laboratories. This is true in the food industry, where producers regularly monitor food and environmental samples for spoilage and pathogenic microbes as an early indication of breakdown in processing hygiene.

Chemically, agar is a polymer made up of subunits of the sugar galactose, and is a component of the cell walls of several species of red algae that are usually harvested in eastern Asia and California. Dissolved in boiling water and cooled, laboratory agar looks gelatinous.
