Screening of bacteria usable in bioremediation of ammonium

Abstract

Bioremediation of ammonium is an important aspect of biological nutrient removal in wastewater treatment processes. However, due to process constraints, inhibiting compounds or more stringent discharge standards the ammonia removal rate can be insufficient. Addition of bacteria to wastewater systems has been shown to increase ammonium removal. In this study, laboratory scale bioremediation experiments were carried out. 27 strains were isolated from latex processing treatment plant and screened to assess their degradative potential for ammonium. Bacterium designated strain S-11 was show good respond. On the basis of their cultural and biochemical characteristics, Strain S-11 closely related to Bacillus sp.
