Bioluminescent Toxicity Testing

Toxicity monitoring methods using a bioluminescent bacterium (Aliivibrio fischeri) are convenient and are especially valuable when the identities of the toxic agents are unknown. The bacterium luminesces as part of its metabolism and is non-invasive, rapid, reproducible, and user-friendly. When exposed to a toxic substance, the cellular respiration of the bacteria is inhibited, reducing light output.  The change in the light is used to calculate percent inhibition which directly correlates to toxicity.

What is BioLight?

BioLight is a custom set of bioluminescent bacteria reagents, consumables and the BioLight Toxy instrument used for acute toxicity testing in the lab or in the field.  Aliivibrio fischeri is the bacterium used in the production of BioLight freeze-dried reagents. The BioLight Toxy measures the changes in the light to indicate the levels of toxicity. Over 3600 chemical compounds are tested simultaneously.

What Our Customers Say



TOXKITS are used for research and toxicity monitoring for a variety of applications.  The test species and the test protocols are the same as in many standardized toxicity tests.Toxkits offer a broad range of aquatic and terrestrial ecotoxicity bioassays with freshwater, seawater, sediment organisms and higher plants according to several international standards and guidelines such as ISO, OECD, USEPA and ASTM.The dormant or immobilized test species can be stored for months and “activated” (= hatched, de-immobilized or germinated) at the time of the performance of the assays.
