The ammonification of peptone showed little correlation between treatments with Cd, Zn (1000 and 5000 µg g⁻¹) and Pb (10000 and 20000 µg g⁻¹) and origin of the soil. Nitrification was considerably ...

Ammonification proceeded rapidly in fresh soils percolated with dilute solutions of glutamate and glycine. There was evidence both from the acceleration of ammonification and bacterial counts that an ...

Fig 1 compares the relative needs for carbon and oxygen of conventional, Sharon and de-ammonification processes for nitrogen removal. The first full-scale plant using the de-ammonification pathway was ...
