PHENYLALANINE MALONATE BROTH (SHAW & CLARKE MEDIUM)

Description

The term enteric bacteria is generally used in reference to organisms of the Family Enterobacteriaceae, many members of which occur in the enteric tract of humans and animals. Members of Enterobacteriaceae are the most frequently encountered bacterial isolates recovered from clinical specimens. Definitive identification of the members of the Enterobacteriaceae may require a battery of biochemical tests. This medium is prepared according to the formulation developed by Shaw and Clarke for differentiating gram-negative enteric bacteria on the basis of their ability to utilize malonate and produce pyruvic acid from phenylalanine.
