The phenylalanine deaminase test is a biochemical test used to identify bacteria that possess the enzyme phenylalanine deaminase. This enzyme plays a crucial role in bacterial metabolism, allowing them to break down the amino acid phenylalanine into phenylpyruvic acid and ammonia. Principle of the Phenylalanine deaminase test The PDA test leverages the specific enzymatic activity
The Salmonella-Shigella (SS) agar is a selective and differential culture medium specifically designed for the isolation and identification of Salmonella and Shigella species from clinical specimens. These bacteria are notorious for causing foodborne illnesses, commonly known as salmonellosis and shigellosis. The SS agar employs a unique combination of ingredients that suppress the growth of unwanted
