Microtox Toxicity TestThe Microtox test measures the light-output ofbioluminescent organisms, vibrio fischeri, when exposedto a potentially inhibitory substance to quantify toxicity Vibrio-fischeri produce light as a by-product of cellularrespirationThe Microtox machine compares the light output of anon-toxic control to the light output of the bioluminescentbacteria exposed to a potentially toxic substance(defoamant)
Microtox Test on FC Rel DefoamantEC 50 (effective concentration where there is a 50% loss of light output) of the Vibriofischeri bacteria is above what typical dosing concentrations of theFC Rel defoamant would be
