Indole-lnduced, Green to Brown-Black Pigment Formation by an Acinetobacter Strain from Beef. Academic Article uri icon


  • In determining aerobic plate counts of surfaces of beef carcasses, green to brown-black colonies of an Acinetobacter sp. appeared on tryptic soy agar plates. Pigmentation was induced by indole-producing organisms in close proximity of or overlapping with the Acinetobacter sp. Addition of indole to culture media also supported pigmentation of the Acinetobacter sp. Indole appeared to be a key intermediate compound in pigment formation.
