Intended Use
A-1 Medium is specifically designed for the detection of coliform organisms in water and food samples, making it an essential tool in microbiological analysis.
Product Summary and Explanation
Since the early 1900s, the enumeration of coliform organisms, particularly E. coli, has been a standard practice for assessing water quality. Traditional methods often involve elevated temperature and most-probable-number (MPN) techniques to analyze the presence of fecal coliforms in various samples. A-1 Medium has been meticulously formulated to enhance the recovery rate of E. coli while minimizing the occurrence of false-positive cultures.
Developed by Andrews and Presnell in 1972, A-1 Medium significantly accelerates the recovery of E. coli from estuarine water, achieving results in just 24 hours, unlike the usual 72 hours required. This medium not only improves the yield of coliform counts but also eliminates the need for a pre-enrichment step, making it a highly efficient option for laboratories.
Whether you're working with source water, seawater, treated wastewater, or food samples, A-1 Medium streamlines the testing process for fecal coliforms. This product adheres to established standard methods for isolating fecal coliforms, ensuring reliable and accurate results for your microbiological assessments.
