Daftar Isi:
- Alcaligenes spp. was found to have the ability to grow and remove ammonium in the medium through the nitrification-denitrification process. This ability was also known as an ammonium treatment in organic wastewater including livestock’s wastewater. In order to further understand its potential to remove ammo- nium in livestock’s wastewater, microbial growth, ammonium, nitrite, and nitrate production of Alcaligenes sp. LS2T were investigated in phosphate medium at dif- ferent carbon/nitrogen ratios (C/N ratios) along with constant airflow. Ammonium sulfate was used as sole nitrogen source with acetate and citrate as an organic car- bon source in a separate medium. Results showed that Alcaligenes sp. LS2T could utilize ammonium as sole nitrogen source which associated with acetate and citrate as carbon source at different C/N ratios, resulting in ammonium removal and pro- duction of nitrite and nitrate at various concentrations in the medium. The highest ammonium removal was found in the acetate C/N 28 medium where 94.44% of initial ammonium was removed.
