Product Name – MacConkey Agar Quantity/Pack Size – 500 gm Form – Powder Grade – Analytical Application – Bacterial Growth
Product Overview
MacConkey Agar is a selective and differential culture medium used primarily for the isolation and identification of enteric bacteria, particularly members of the Enterobacteriaceae family. This agar is designed to inhibit the growth of Gram-positive bacteria while allowing Gram-negative bacteria to grow, making it an essential tool in microbiological laboratories. The medium contains bile salts and crystal violet, which are inhibitory to Gram-positive organisms, and lactose, which is fermented by certain Gram-negative bacteria, leading to the production of acid and the formation of pink colonies. MacConkey Agar is widely used in clinical, food, and environmental microbiology for the detection of pathogens such as Escherichia coli and Salmonella species. Its formulation ensures reliable and consistent results, making it a trusted choice for laboratories worldwide.
