Bioremediation of ammonia and nitrite in polluted water

July 2011

High ammonia nitrogen is a key limiting factor in polluted waters or intensive aquaculture system. Removal of unionized ammonia (NH3) and nitrite (NO2) through biological activity is thus an important tool for changing such ecosystem. Nitrifying bacterial inoculants are the biologically active materials which may be used in intensive aquaculture for bioremediation. In all, 12 treatments were used with two replications...
