General description

DMACA Indole disks are used for indole test to determine the ability of an organism to split tryptophan into indole and α-aminopropionic acid. The presence of indole can be detected by the addition of DMACA which results in a bluish-purple complex. With this method, it is possible to differentiate Escherichia coli from Klebsiella.
