Description

Method

The Colifast technology is based on a chemical reaction between a substrate in the growth medium and enzymes produced by the coliform bacteria. The bacterial enzyme β-D-galactosidase hydrolyses the substrate 4-methylumbelliferyl-β-D-galactoside, which result in the release of the fluorescent product 4-methylumbelliferone (MU). In addition to substrate, activators and growth factors, the medium comprise inhibitors that prevents. The growth of non-coliform bacteria corresponds to an increase amount of β-D-galactosidase (enzyme). The subsequent increase in the amount of MU (Fluorescent product) result in higher value on the instrument (Colifast Micro Detector). The incubation temperature selects thermotolerant coliforms at 44°C and total coliforms at 37°C.
