Some of these organisms have significant capacities to both heterotrophically nitrify and denitrify [2, 10, 19] and some synthesize [N.sub.2]O or [N.sub.2] during the course of heterotrophic nitrification [17, 20] or heterotrophic nitrification-aerobic denitrification metabolism [10,14-16,18, 21].
"Our preliminary research indicated that nitrifying bacteria protected in pellets could nitrify animal lagoon wastewater at rates comparable to those used in Japan to clean up municipal wastewater systems," says Vanotti.
Nitrification in agricultural systems is thought to be mostly carried out by autotrophic bacteria (Jia and Conrad 2009), although some autotrophic archaca and heterotrophs can also nitrify. The mechanism of [N.sub.2]O production from nitrification has not been systematically determined (Khalil et al.
