S2Media™ 10x A-1 Medium
S2Media™ 10x A-1 Medium is a selective broth used for isolation and presumptive identification of fecal coliforms in water. Andrews and Presnell developed A-1 Medium in 1972 to recover Escherichia coli from estuarine water in 24 hours instead of 72 hours, and in greater numbers without pre-enrichment. 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.
