Product Description
MacConkey Agar II without CV is a widely used microbiological medium designed for the selective isolation and differentiation of gram-negative bacteria. This variant excludes crystal violet (CV), making it suitable for specific research applications where CV interference is a concern. The medium contains bile salts and lactose, which inhibit gram-positive bacteria while allowing gram-negative bacteria to grow. Lactose-fermenting colonies appear pink/red due to pH changes, while non-fermenters remain colorless.
This 500 gm pack from Himedia is ideal for academic labs, research institutions, and diagnostic centers. Whether you’re studying bacterial cultures or conducting quality control tests, this medium ensures reliable results.

The formulation adheres to standard microbiological protocols, ensuring consistency in performance. It’s commonly used in clinical microbiology, food testing, and environmental monitoring. The powder form allows for easy preparation, and the medium can be sterilized by autoclaving before use.
For researchers and students working on bacterial identification, MacConkey Agar II without CV is an essential tool. Its selective properties help in distinguishing between lactose fermenters (like E. coli) and non-fermenters (like Salmonella), making it a staple in microbiology labs.
