The Microtox FX Analyser system can perform a dual function; Toxicity Testing and Microbial Monitoring. The Microtox FX system uses a strain of naturally occuring luminescent bacteria called Alivibrio Fischeri to provide acute toxicity detection. The bacteria emit light as a natural part of their matabolism. Exposure to a toxic substance cuases disruption of the respiratory process of the bacteria resulting in a reduced light output.
For microbial detection, ATP testing is performed. All organisms contain ATP (Adenosine Triphosphate) as their main energy source. The amount of ATP in a sample is directly proportional to the biomass of the sample. ATP reacts with luciferin/luciferase, the enzyme system present in firefly tails, to produce light. In the reaction, each molecule of ATP produces one photon of light. The light output of this reaction can be accurately measured using the Microtox FX Analyser system.
