Utilization of heterotrophic and autotrophic bacteria in aquaculture
... Although both types of bacteria can nitrify inorganic ions (NH3, NO2, NO3), heterotrophic bacteria are far less likely to conduct nitrification in aquaculture systems due to their reliance on organic matter as a major source of energy. The addition of carbon to increase the carbon/nitrogen ratio in ...
