Biogroup has developed a wide variety of analytical techniques in the field of Biology, including Toxicity Tests and Microbiological Analysis.

 

Toxicity test

Toxicity Tests, commonly called "Bioassays", measure the toxic or adverse effects of samples on a particular organism.

Toxicity Tests are Laboratory experiments used to assess the biological impacts on the environment by direct exposure of aquatic organisms to the water or sediment in question. The Biogroup research staff conducts a series of Toxicity Tests for samples of:

  • Industrial and sewer effluents.
  • Superficial and underground waters
  • Sediments from rivers, streams, lakes and oceans.
  • Ecological Risk Assessments in Contaminated Sites.

Toxicity test. Chronic and Acute.

Invertebrates. Cladocera (Ceriodaphnia dubia) survival and reproduction.
Cladocera (Daphnia magna) survival, growth, and reproduction.
Cladocera (Daphnia pulex) survival.
Algae - Green microalgae (Selenastrum carpicornutum) growing.
Amphipod. Hyallela azteca, survival in sediments.
Vegetables (Lactuca sativa) (Lycopersicon esculentum) (Cucumis sativus) (Glycine max) (Brassica oleracea) (Avena sativa) (Lolium perenne) (Allium cepa) (Daucus carota) (Zea mays), Germination and root elongation test

Ames test

It consists of a biological assay to evaluate the mutagenic potential of chemical compounds.

As cancer is often linked to DNA damage, the test also serves as a rapid assay to estimate the carcinogenic potential of a compound, since standard tests for carcinogenicity performed on rodents take years to complete and are expensive to do. .
