Test Biota

Aquatic and terrestrial test biota

 

Aquatic and terrestrial test biota are used worldwide in ecotoxicological studies.  These bioassays provide qualitative and quantitative data on adverse effects from chemicals or environmental pollutants on living organisms in acute and chronic toxicity tests.

Microbiotests provides a wide range of aquatic and terrestrial test biota that can be used for standardised and culture-independent toxicity testing , bioassay services, or for other research applications.
These freshwater, marine and estuarine biota can also be used as starter culture to maintain live stocks or as back-up in the culturing facility of environmental laboratories.

Many of these test species are identical to the test organisms used in standardised toxicity tests.
As an example, the test biota are used to study whole effluent toxicity tests under national permit and regulatory frameworks.

The intensive culturing of aquatic test organisms and the production of dormant eggs or immobilised test species is one of the key activities and expertise of Microbiotests.

Microbiotests certifies the highest quality of the biological material produced.
All test organisms are cultured in-house under strictly controlled conditions resulting in standardised organisms
for reliable toxicity testing and research.
Every single batch of test biota is subject to thorough internal quality control screenings and reference tests according to international standards and guidelines to guarantee the biological quality and viability of the test species.
