[Comparison between rapid detection method of enzyme substrate technique and multiple-tube fermentation technique in water coliform bacteria detection].

OBJECTIVE: To compare between rapid detection method of enzyme substrate technique and multiple-tube fermentation technique in water coliform bacteria detection. METHODS: Using inoculated and real water samples to compare the equivalence and false positive rate between two methods. RESULTS: Results demonstrate that enzyme substrate technique shows equivalence with multiple-tube fermentation technique (P = 0.059), false positive rate between the two methods has no statistical difference. CONCLUSION: It is suggested that enzyme substrate technique can be used as a standard method for water microbiological safety evaluation.
