Description
Overview
MFC Agar is a specialized culture medium designed for accurate fecal coliform testing in drinking water and source water. It supports membrane filtration workflows used in routine water microbiology and regulatory monitoring.
Because water quality directly affects public health, laboratories require fast and dependable results. This medium provides strong selectivity while maintaining high recovery. As a result, technicians can identify fecal coliforms with confidence.
Moreover, its balanced formulation ensures consistent colony development. Therefore, daily testing becomes more efficient and reproducible.
Why It Works
The formula integrates tryptone, polypeptone, and yeast extract to supply essential nitrogen, amino acids, and vitamins. Lactose serves as the fermentable carbohydrate that drives indicator reactions.
At the same time, bile salts inhibit non-target organisms. Aniline blue and rosolic acid create clear visual contrast. Consequently, fecal coliforms form characteristic blue colonies, which simplifies interpretation.
Because every component plays a defined role, the medium delivers stable performance across batches. Therefore, laboratories can standardize workflows without frequent adjustments.

Performance in Daily Testing
During membrane filtration, water samples pass through sterile filters. The filter then transfers to prepared plates. Target organisms grow rapidly under incubation.
Because fecal coliforms ferment lactose, they interact with the indicators. As a result, distinctive blue colonies appear. This contrast reduces reading errors and shortens analysis time.
Moreover, the selective agents suppress competing flora. Therefore, background growth remains low even in complex samples.
Built for Water Safety
Every water test contributes to public confidence. Laboratories need a medium that supports accuracy, speed, and compliance.
This solution enables technicians to detect contamination early. Consequently, corrective actions can begin sooner. In long-term monitoring programs, it ensures trend stability and data integrity.
Used in water microbiology worldwide, this medium strengthens routine testing and regulatory compliance. By integrating it into your workflow, your lab gains efficiency, clarity, and dependable results.
