About this item

Test water from your own environment for fecal coliforms.

Complete assay in 30 minutes, and grow overnight
Non-pathogenic bacteria provided
Easy to interpret results
Includes instructor's guide and discussion questions

In this experiment, students will test control and environmental water samples for the presence of total coliform bacteria and E. coli using color changing enzyme assays. Testing drinking water for every possible type of pathogenic bacteria is slow and costly. Thus, drinking water is tested for coliforms - including the familiar E. coli. Presence of coliforms is an indicator of fecal contamination.

Bactobead refill contains positive control organisms: Escherichia coli, and Citrobacter freundii.
