MacConkey Agar w/o Crystal Violet (7236)
Intended Use
MacConkey Agar without Crystal Violet is expertly formulated for the isolation and differentiation of Gram-negative enteric bacilli. Ideal for microbiological analysis, this medium is essential for laboratories focusing on selective growth conditions.
Product Summary and Explanation
Developed from the classic bile salt-neutral red-lactose agar, MacConkey Agar W/O Crystal Violet enhances the differentiation of enteric bacteria, originally tailored to distinguish strains of Salmonella typhosa from coliforms. Over the years, modifications of the original MacConkey formula have been implemented to boost growth rates of specific pathogens, including Shigella and Salmonella. Key enhancements comprise the integration of 0.5% sodium chloride, reduced agar concentration, and proportions of bile salts and neutral red to optimize the differential reactions.
As a differential medium, MacConkey Agar W/O Crystal Violet offers a versatile growth environment due to its lower selectivity compared to standard MacConkey Agar. The absence of Crystal Violet allows for the cultivation of enterococci, staphylococci, and Mycobacterium species, making it an invaluable resource for a broad range of microbiological applications.
