Water quality. Determination of the inhibitory effect of water samples on the light emission of Vibrio fischeri (Luminescent bacteria test) - Method using freeze-dried bacteriaWhat is this standard about? 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
