This article discusses a method that has been recently developed that allows the direct quantitative enumeration of the fecal‐coliform‐organism group by the membrane filter (MF) technique without the need for prior enrichment or subsequent chemical testing. A medium for fecal coliform organisms (MFC) is recommended that contains no inhibitory substances for coliform bacteria and that depends on an incubation temperature of 44.5°C for 24 hrs. for its selectivity.
