Phenylalanine Agar 1040 Condalab

Phenylalanine Agar is a solid medium used for differentiating Proteus, Providencia and Morganella species from other Enterobacteriaceae, based on the deamination of phenylalanine to phenylpyruvic acid by enzymatic activity. Some strains of Enterobacter and a few non-fermenting Gram-negative bacilli are also capable of deaminating phenylalanine. DL-Phenylalanine is deaminated to phenylpyruvic acid. Yeast extract provides vitamins, particularly of the B-group, and other nutrients for growth. Sodium chloride supplies essential electrolytes for transport and osmotic balance. Sodium phosphate is the buffer and Bacteriological agar is the solidifying agent.
