MI Agar is a chromogenic/fluorogenic medium used to detect and enumerate Escherichia coli and total coliforms in drinking water by the membrane filtration technique.

• Peptone provides nitrogen, carbon, and amino acids
• Yeast extract provides trace elements, vitamins, and amino acids
• Lactose is a carbon source and fermentable carbohydrate
• Sodium chloride maintains osmotic equilibrium

MI Agar is approved for use by certified drinking water laboratories for microbial analysis of potable water. Other uses include recreational, surface or marine water, bottled water, groundwater, well water, treatment plant effluents, water from drinking water distribution line, drinking water source water and possibly foods.
