Product Description
HiCrome® MacConkey Sorbitol Agar Base is a specialized microbiological medium designed for the selective isolation and differentiation of E. coli O157:H7, a pathogenic strain responsible for severe foodborne illnesses. This agar base is formulated with sorbitol as the primary carbohydrate source, allowing for the differentiation of sorbitol-fermenting and non-fermenting bacteria.
The medium incorporates bile salts and crystal violet to inhibit Gram-positive bacteria, while neutral red acts as a pH indicator, turning colonies pink or red when sorbitol is fermented. E. coli O157:H7, which does not ferment sorbitol, appears as colorless or pale colonies, making it easy to identify.
This agar is widely used in clinical, food, and environmental microbiology laboratories for routine screening and research purposes. Its high selectivity and differential properties make it an essential tool for microbiologists studying enteric pathogens.
For researchers and students working on bacterial identification, HiCrome® MacConkey Sorbitol Agar Base provides reliable results with clear visual differentiation. Whether you’re conducting food safety tests or academic research, this medium ensures accurate detection of E. coli O157:H7.

FAQs
What is the purpose of sorbitol in this agar?
Sorbitol is used as the primary carbohydrate source to differentiate between sorbitol-fermenting and non-fermenting bacteria, particularly E. coli O157:H7.
How does this medium inhibit Gram-positive bacteria?
The medium contains bile salts and crystal violet, which suppress the growth of Gram-positive bacteria while allowing Gram-negative bacteria to thrive.
Can this agar be used for other E. coli strains?
