反応手順
Principle of Step 1: ONPG substituting for lactose is metabolized with β-galactosidase. At 44.5° C. E. coli grow and utilize ONPG and produce indole. β-galactoside turns the medium yellow. In the yellow colored medium, both fecal coliforms and E. coli are present. In samples which do not have a yellow color, there are no fecal coliforms and E. coli.
