coliform bacteria

coliform bacteria A group of aerobic, lactose‐fermenting bacteria, of which Escherichia coli is the most important member. Most coliforms are not harmful, but since they arise from faeces, they are useful as a test of faecal contamination, and particularly as a test for water pollution. Some strains of E. coli produce toxins, or are otherwise pathogenic, and are associated with food poisoning.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content.
