 (E. coli), a rod-shaped member of the coliform group, can be distinguished from most other coliforms by its ability to ferment lactose at 44°C, and by its growth and color reaction on certain types of culture media. When cultured on an EMB plate, a positive result for E.Coli is a metallic green media with dark purple colonies. Unlike the general coliform group, E. coli are almost exclusively of fecal origin and their presence is thus an effective confirmation of faecal contamination. Typically, E. coli are about 11% of the coliforms in human faeces.
