PHENYLALANINE AGAR

The ability of Proteus species to convert phenylalanine to phenylpyruvic acid is an important reaction in the differentiation of Enterobacteriaceae. Based on this criterion, Buttiaux developed Phenylalanine Agar for differentiation of Proteus and Providencia group from other members of Enterobacteriaceae by the ability of organism in the genera within Proteus to deaminate phenylalanine. Phenylalanine Agar is the modification of the medium originally developed by Ewing et al.

for di?erentiation of Proteus & Providencia from other members of Enterobacteriaceae on the basis of their ability to form phenyl pyruvic acid from phenylalanine
