Dimethyl alpha naphthylamine
WebAfter incubating the nitrate broth, add a dropperful of sulfanilic acid and α-naphthylamine. If the organism has reduced nitrate to nitrite, the nitrites in the medium will form nitrous acid. When sulfanilic acid is added, it will react with the nitrous acid to produce diazotized sulfanilic acid. This reacts with the α-naphthylamine to form a ...
