“…The nitrification activity of ALNS, obtained before immobilization using the inorganic medium (300 mg NH 4 -N L -1 ), was 15.4 mg-N g-MLSS -1 h -1 . This rate is similar to values from 13.1 to 17.5 mg-N g-MLSS -1 h -1 reported by Furukawa et al (1993) with marine nitrifiers but higher than typical values of 0.2-6 mg N g-MLSS -1 h -1 reported for fresh water activated sludgetype systems (Wild et al, 1971;Loehr et al, 1973;Sharma and Ahlert, 1977). The composition of the inorganic medium used to grow the ALNS (table 1) was selected to prevent nitrification inhibition during lagoon liquid testing by high NH 3 .…”

uring recent decades, animal production methods in the U.S. have changed from small, individual operations to large, confined, commercial enterprises. This change has caused many problems for the swine industry including emission of ammonia (NH 3) from lagoons. Liquid swine manure is usually treated and stored in large (0.25 to 5 ha) anaerobic lagoons before land application. It may be anticipated that 50 to 80% of the nitrogen (N) entering animal lagoons will escape to the atmosphere through NH 3 volatilization (
