There are five major Microtox tests including the Basic Test, the 100% Test, the Solid Phase Test, the Comparison Test, and the Inhibition Test. Of these five tests, three are used for sediment and soil testing including the Basic Test, the 100% Test and the Solid-Phase Test.[1] All of these versions follow the same general method of reconstituting the Allivibrio fischeri reagent in the Reconstitution Solution.
