Aminopeptidase profiles of various bacteria.
The aminopeptidase specificity of 24 strains of bacteria was determined fluorometrically by use of a series of alpha-amino acid beta-naphthylamides as substrates. Provided that strict control over medium and growth time was adhered to, a reproducible profile of aminopeptidase activity was obtained which could be used for the identification of bacteria.
