Which type of bacteria is more resistant to chlorination?

Coliform bacteria are a group of bacteria commonly found in the environment, especially in the intestines of warm-blooded animals. They serve as an indicator of fecal contamination and the potential presence of pathogenic organisms. Coliform species, particularly E. coli, exhibit a level of resilience to chlorination compared to other bacterial types, meaning they can sometimes survive sanitization efforts that aim to reduce or eliminate bacteria in water treatment processes.

The reason coliform bacteria can be more resistant to chlorination has to do with their cellular structure and environmental factors. Their protective cell walls can sometimes withstand chlorination better, enabling these organisms to survive disinfection measures that would typically be effective against more sensitive bacteria.

Understanding the resistance of coliform bacteria to chlorination emphasizes the importance of monitoring these organisms in water quality assessments, as their presence indicates the potential for more harmful pathogens that may not be tested in routine disinfection processes. This insight drives the need for proper treatment methods that address not only coliforms but also other potential contaminants in the environment.
