Abstract

THE phenylalanine test is of great value for investigating cultures of organisms in the family Enterobacteriaceae. Organisms in the Proteus group are able to de-aminate the amino-acid, phenylalanine, to form phenylpyruvic acid, whereas members of the other groups in the family are unable to do so. Buttiaux et al. 1 claim that this test is more reliable than the urease test for the identification of Proteus strains.
