m-ColiBlue24 broth

The m-ColiBlue24 broth simultaneously detects and identifies both total coliforms and Escherichia coli (E. coli). Complete enumeration is accomplished within 24 h, requiring neither a confirmation step nor fluorescent lamps. Visual interpretation of results is easy, with E. coli colonies appearing as blue and other coliforms as red. This direct enumeration is more accurate and precise than such statistical-based tests as multiple-tube fermentation (MTF) and most-probable number (MPN). This broth method of detection has been approved by the U.S. Environmental Protection Agency for monitoring drinking water and wastewater, and can also be used to detect coliforms in other types of waters: bottled, surface, ground, well and recreational (both fresh and marine), as well as process water for ultrapure chemical processing.
