acumedia<sup>®</sup> A-1 Medium

acumedia® A-1 Medium

• Intended Use: A-1 Medium is used for the detection of coliform organisms in water and food
• Product Summary: Since the early 1900's enumeration of coliform organisms, specifically E. coli, have been used to determine water purity. Elevated temperature and most-probable-number (MPN) methods are routinely used for analysis of water and food samples for presence of fecal coliforms. A-1 Medium was formulated to hasten E. coli recovery and reduce the incidence of false positive cultures.
In 1972 Andrews and Presnell developed A-1 Medium.1 This medium recovers E. coli from estuarine water in 24 hours instead of 72 hours, and in greater numbers without the pre-enrichment step. A-1 Medium can be used in a single step procedure for the detection of fecal coliforms in source water, seawater, treated wastewater, and foods. A-1 Medium conforms to standard methods for the isolation of fecal coliforms in water and foods.
