Product Description
MacConkey Sorbitol Agar is a specialized medium designed for the selective isolation and differentiation of Escherichia coli (E. coli) strains, particularly those that do not ferment sorbitol. This agar is widely used in clinical and research laboratories to identify pathogenic E. coli, including the O157:H7 serotype, which is a major cause of foodborne illnesses.
The medium contains sorbitol as the primary carbohydrate source, along with bile salts and crystal violet, which inhibit the growth of Gram-positive bacteria. The inclusion of neutral red as a pH indicator helps distinguish between sorbitol-fermenting and non-fermenting colonies. Sorbitol-negative E. coli colonies appear colorless, while sorbitol-positive colonies turn pink or red.
This product is manufactured by Himedia, a trusted name in microbiology media, ensuring high quality and consistent performance. Whether you’re a student, researcher, or educator, MacConkey Sorbitol Agar is an essential tool for accurate microbial identification.
