Product Description
HiCrome® MacConkey Sorbitol Agar Base is a specialized medium designed for the selective isolation and differentiation of Escherichia coli, particularly sorbitol-non-fermenting strains like E. coli O157:H7. This agar base is widely used in clinical and research laboratories for its reliability in detecting pathogenic E. coli, making it an essential tool for food safety testing, water analysis, and microbiological studies.
The medium contains sorbitol as the primary carbohydrate source, allowing for the differentiation of sorbitol-fermenting and non-fermenting bacteria. The addition of bile salts and crystal violet inhibits the growth of Gram-positive bacteria, ensuring selective isolation of Gram-negative organisms. The presence of neutral red as a pH indicator helps in visualizing fermentation patterns, with sorbitol-fermenting colonies appearing pink and non-fermenting colonies remaining colorless.
HiCrome® MacConkey Sorbitol Agar Base is easy to prepare and provides consistent results, making it a preferred choice for researchers and lab technicians. Whether you’re conducting routine microbial analysis or advanced research, this agar base offers the precision and reliability needed for accurate E. coli detection.

How to Use HiCrome® MacConkey Sorbitol Agar Base
Preparing and using this agar base is straightforward. Follow these steps for optimal results:
- Dissolve 50 grams of the powder in 1 liter of distilled water.
- Heat the solution to boiling while stirring to ensure complete dissolution.
- Autoclave the medium at 121°C for 15 minutes to sterilize.
- Cool the medium to 45-50°C and pour into sterile Petri dishes.
- Allow the agar to solidify before inoculating with the sample.
- Incubate the plates at 35-37°C for 18-24 hours and observe for colony characteristics.
Sorbitol-fermenting colonies will appear pink, while non-fermenting colonies, such as E. coli O157:H7, will remain colorless. This clear differentiation makes it easier to identify and isolate specific strains for further analysis.
Applications of MacConkey Sorbitol Agar
This agar base is versatile and finds applications in various fields, including:
- Clinical microbiology for detecting pathogenic E. coli in patient samples.
- Food safety testing to identify contamination in meat, dairy, and processed foods.
- Water quality analysis to ensure microbial safety in drinking and recreational water.
- Research laboratories studying bacterial metabolism and antibiotic resistance.
Its selectivity and differential capabilities make it an invaluable tool for professionals working in public health, environmental science, and biomedical research.
