Study design
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, adapted
- Details on inoculum:
- - Source of inoculum/activated sludge (e.g. location, sampling depth, contamination history, procedure):
On-site sampling carried out at 10 locations in Japan. Return sludge was collected from sewage plants and surface water and surface soil in contact with the atmosphere was collected from rivers, lakes and the sea.
- Preparation of activated sludge; The filtrate (5 l) of the supernatent of the activated sludge cultivated for abut 3 months was mixed with the mixed filtrate ( 5 l) of the supernatent of a sludge collected newly at each location. The mixed filtrate (10 l) was aerated after the pH value of the mixture was adjusted to 7.0 +/- 1.0.
- Cultivation: Approximately 30 minutes after ceasing aeration of the sludge mixture, supernatent corresponding to about 1/3 of the whole volume was removed. Dechlorinated water was added to te remaining portion so that the total volume reached 10 litres. This mixture was aerated for 30 minutes or more, then a pre-determined amount of synthetic sewage was added to the mixture so that the concentration of the synthetic sludge was 0.1% in the volume of dechlorinated water added. This procedure was repeated once every day. cultivation was carried out at 25 +/- 2°C.
- Synthetic sludge: Glucose, peptone and potassium dihydrogenphosphate were dissolved in purified water to obtain 50 g/l of the solution for each component. The pH of the solution was adjusted to 7.0 +/- 1.0 woth sodium hydroxide. - Duration of test (contact time):
