Question

With the increased use of chloramines (e.g., NH2CI) as a residual disinfectant in water supply, ammonia concentrations in drinking water have increased. Nitrifying microorganisms use ammonia (NH4) as an electron donor (oxidized to NO) and oxygen (Oz) as an electron acceptor (reduced to H2O) in a process known as nitrification. The microorganisms use inorganic carbon (dissolved COz and HCO3) as their carbon sources. These microorganisms can be classified as ( )? A. photoautotroph B. chemoautotroph C. chemoheterotroph
