Abstract
A fluorogenic substrate for tryptophanase useful for identifying an unknown microorganism is a fluorescent dye linked to an amino acid by a carbamate or thiocarbamate group. In preferred substrates, the dye is fluorescein or 7-amino-4-methyl coumarin and the amino acid linked thereto is cysteine, threonine or serine.
