Thermo Scientific™ Phenylalanine Agar

Description

• Differentiate enteric gram-negative bacilli (e.g., Morganella and Providencia 1,2 ) on the basis of deamination of phenylalanine using Thermo Scientific™ Remel™ Phenylalanine Agar
• In 1950, Henriksen reported Proteus species were able to convert phenylalanine to phenylpyruvic acid 3
• Later, Buttiaux et al
• described a method for detection of phenylpyruvic acid, formed as a result of phenylalanine deamination 4
• Bynae incorporated phenylalanine into an agar used to grow the organism 5,6
• Ewing et al
• modified the formulation of Bynae by omitting proteose peptone 7
• 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 f
