title: 24 hours of anoxic incubated with 10mM nitrate: Sample Anoxic N 24h-replicate1
design: The aerobic sewage treatments (1 l sewage in 2-l glass bottles) were carried out in duplicate and were aerobically incubated at 25C with stirring at 160 rpm for two weeks. Samples (10 ml) were withdrawn from the sewage treatments at 0.5 hour and were stored at -80C.
