Differentiate enteric gram-negative bacilli (e.g., Morganella and Providencia) on the basis of deamination of phenylalanine using InMicro® Prepared: Phenylalanine Agar.
Differentiate enteric gram-negative bacilli (e.g., Morganella and Providencia) on the basis of deamination of phenylalanine using InMicro® Prepared: Phenylalanine Agar. In 1950, Henriksen reported Proteus species were able to convert phenylalanine to phenylpyruvic acid. Later, Buttiaux et al. described a method for detection of phenylpyruvic acid, formed as a result of phenylalanine deamination. Bynae incorporated phenylalanine into an agar used to grow the organism. Ewing et al. modified the formulation of Bynae by omitting proteose peptone.
The ability of an organism to oxidatively deaminate phenylalanine to phenylpyruvic acid is an important reaction in the differentiation of Enterobacteriaceae. This criterion is used to identify and differentiate enteric gram-negative bacilli.
