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.
5 mL of the Kovac Reagent was added and gently shaken to determine the production of Indol.
La cepa ipdC- es una cepa hipoproductora de acido indol acetico; por lo cual, se espera menos induccion de crecimiento, pero aun no hay literatura especializada publicada que describa sus efectos reales.

Bacteria were identified on the basis of colony characteristics, Gram stain, pigment production and biochemical reactions, including agar Triple Sugar Iron (TSI), citrate, urease, indol, Methyl Red (MR), Voges Proskauer (VP), nitrate and motility tests, catalase activity test, tube coagulase test, and aerobic fermentation of several carbohydrates.
Luego, se efectuaron las pruebas de catalasa y oxidasa, rojo de metilo, Voges-Proskauer, produccion de indol, reduccion de nitratos, uso del citrato como fuente de carbono, desaminacion de la fenilalanina, motilidad, hidrolisis de la gelatina y la urea, utilizacion del malonato, fermentacion de carbohidratos (glucosa, lactosa, sacarosa, maltosa y trehalosa), produccion de gas y H2S, las cuales son recomendadas para la identificacion de enterobacterias [4, 16, 19, 23, 40] siendo claves para la caracterizacion de aislados de M.
En el AFP se obtuvieron resultados positivos asociados a la presencia de metabolitos de tipo indol y sus derivados, esteroides, acidos grasos insaturados y compuestos con carbonilos.
