Produccion de indol a partir de triptofano: las suspensiones de microorganismos se inocularon en el medio adecuado (peptona de carne 1%, D,L-triptofano 0,1%, NaCl 0,5%, pH 7,2) y se incubaron por 24 a 48 h a 37[grados]C.
Then 0.5 mL of the Kovac Reagent was added and gently shaken to determine the production of Indol. It was taken as positive when adding the reagent presented the formation of a red colour band at the top of the medium.
