Product Description
Phenol Red Egg Yolk Polymyxin Agar Base is a specialized microbiological medium designed for the selective isolation and differentiation of Bacillus species. This agar base, formulated by Himedia, incorporates phenol red as a pH indicator, egg yolk for lecithinase activity detection, and polymyxin to inhibit gram-negative bacteria. It is widely used in clinical and research laboratories for identifying pathogenic Bacillus strains, including Bacillus cereus.
The medium supports the growth of Bacillus species while suppressing unwanted microorganisms, making it ideal for diagnostic and quality control applications. Its composition ensures clear visualization of lecithinase activity, a key virulence factor in Bacillus infections. Researchers and students rely on this agar for accurate and reproducible results in microbial studies.
When preparing the medium, follow standard microbiological protocols to achieve optimal performance. The powdered form allows for easy reconstitution, and the 100 gm pack size is convenient for frequent lab use. For best results, store the product in a cool, dry place and avoid exposure to moisture.

FAQs
What is the shelf life of Phenol Red Egg Yolk Polymyxin Agar Base?
The powdered medium has a shelf life of 24 months when stored properly in a cool, dry place. Prepared plates should be used within 7 days.
Can this agar be used for non-Bacillus species?
While designed for Bacillus, it may support other gram-positive bacteria. However, polymyxin inhibits most gram-negative organisms.
How do I interpret lecithinase activity on this agar?
Lecithinase-positive colonies, like Bacillus cereus, produce a white precipitate around the colony due to egg yolk breakdown.
Is this product suitable for student labs?
Yes, it is commonly used in educational settings for teaching microbial identification techniques.
Where can I buy Phenol Red Egg Yolk Polymyxin Agar Base online?
You can purchase this high-quality Himedia agar base from eqipped, ensuring authentic products and reliable delivery.
