ISO 11348 describes three methods for determining the inhibition of the luminescence emitted by the marine bacterium Vibrio fischeri (NRRL B-11177). This part of ISO 11348 specifies a method using freeze-dried bacteria.
This method is applicable to:
⎯ waste water;
⎯ aqueous extracts and leachates;
⎯ fresh water (surface and ground water);
⎯ sea and brackish water;
⎯ eluates of sediment (freshwater, brackish and sea water);
⎯ pore water;
⎯ single substances, diluted in water.
