Chromogenic Escherichia Coli Agar A1 Quality – HX-Media

Chromogenic Escherichia Coli Agar – HX-Media

Product Overview

Chromogenic Escherichia coli Agar is a selective and differential culture medium designed for the isolation and identification of Escherichia coli Agar from food, water, and environmental samples. The medium contains chromogenic substrates that react with specific enzymes (such as β-glucuronidase), resulting in distinctively colored colonies for rapid and reliable identification.

Selective agents suppress the growth of non-target organisms, ensuring clearer differentiation and improved accuracy. Target organisms typically produce characteristic colored colonies, allowing quick presumptive identification without extensive confirmatory testing.

This medium is widely used in food safety testing, water quality analysis, environmental monitoring, and clinical laboratories. It offers high sensitivity, faster turnaround time, and ease of interpretation, making it ideal for routine microbiological analysis and quality control applications.
