ColiComplete is a patented substrate supporting disc method containing both XGAL and MUG. It is designed to simultaneously detect Total Coliforms and E. coli in food products. The Beta-galactosidase enzyme produced by coliforms reacts with the chromogenic XGAL substrate to produce a visually detectable insoluble blue dye. The Beta-glucuronidase enzyme found in E. coli reacts with the MUG substrate to produce a blue fluorescent reaction under long wave UV light.  

Rapid Enumeration of Total Coliforms and E. coli

ColiComplete provides confirmed quantitative E. coli results in as few as 28 hours and confirmed total Coliforms result in 48 hours.

Simple to Use

Just add the patented ColiComplete disc to Lauryl Sulfate Broth (LST) tubes at the time of inoculation, incubate and read results.  Use the Most Probably Number (MPN) format for quantitative results.  No transfers are necessary.

Reduced Testing Costs

Simultaneous detection of both E. coli and total Coliforms from a single test.  Results are confirmed and require no subculturing.
