Nitrifying Bacteria


Nitrifying bacteria include the genera Nitrosomonas, Nitrobacter and Nitrosococcus. They are an important group of bacteria that can be used as an indicator for the presence of organic nitrogenous material in water. During the nitrification process, bacteria aerobically oxidize ammonium to nitrite and then further to nitrate. Aggressive nitrifying bacteria can produce high concentrations of nitrates. This could pose a potential health risk, particularly to infants who haven’t developed a tolerance to nitrates. The presence of aggressive nitrifying bacteria in water may indicate contamination from a sewage system, septic tank or industrial waste.

Types of water to be tested include potable water plumbing systems, well water.
