A simple and sensitive test for demonstrating mercaptan formation by microorganisms has been described. A positive test for mercaptans is indicated by the formation of white vapors when a few drops of iodine-azide reagent 3 grams of sodium azide in 100 milliliters of 0.1N iodine is added to one or two milliliters of a broth culture. A positive reaction has been observed with several species of Pseudomonas, a species of Serratia, and a few lactose fermenting species.
