Product Description
MacConkey Sorbitol HiVeg Agar is a specialized microbiological medium designed for the selective isolation and differentiation of sorbitol-non-fermenting Escherichia coli strains, particularly E. coli O157:H7. This medium is widely used in clinical, food, and environmental microbiology labs for its ability to distinguish pathogenic strains from non-pathogenic ones.
The agar contains sorbitol as the primary carbohydrate source, allowing researchers to identify strains that cannot ferment sorbitol. The addition of bile salts and crystal violet inhibits the growth of Gram-positive bacteria, ensuring selective isolation of Gram-negative organisms. The HiVeg formulation ensures high-quality results without animal-derived components, making it suitable for vegan-friendly lab practices.
This medium is particularly useful in food safety testing, where rapid detection of E. coli O157:H7 is critical. The distinctive color change (sorbitol-fermenting colonies appear pink, while non-fermenters remain colorless) simplifies identification, reducing the need for additional confirmatory tests.
For researchers and lab technicians, MacConkey Sorbitol HiVeg Agar offers reliability and consistency in microbial analysis. Whether you’re working in a university lab, diagnostic center, or food testing facility, this medium provides accurate results for your experiments.
