The CNC-indole coating was the most effective in reducing ... WebA positive indole test is indicated by the formation of a red color in the reagent layer on top of the agar deep within seconds of adding the reagent. If a culture is indole negative, the reagent layer will remain yellow or be slightly cloudy. See Indole Atlas images—Alternative Methods for Determining Indole Production for MIO result images.
