Caption:
This photograph depicts the colonial growth pattern displayed, by Salmonella typhimurium bacteria, cultured on a Hektoen enteric (HE) agar medium. S. typhimurium colonies grown on HE agar are blue-green in color, for this organism is a lactose non-fermenter, but it does produce hydrogen sulfide, (H2S), therefore there can be black-colored deposits present.
