Certain members of the family Enterobacteriaceae developing on beef steaks packaged in modified atmospheres may grow on the medium CFC (Cephaloridine‐Fucidin‐Cetrimide), which is selective for pseudomonads. The addition of arginine (1% w/v) and the pH indicator phenol red (0.002% w/v) to this medium differentiated between the two groups. The pseudomonads produced ammonia from arginine, whereas Enterobacteriaceae generally did not use this substrate. The alkaline drift in pH in and around pseudomonad colonies gave a pink colouration with phenol red.
