Microbial Effects

Influence of wealth chemicals on the intestinal flora

The working group Micro-/Molecular Biology of the Karlsruhe Institute of Technology (KIT-IFG) headed by Prof. Dr. Thomas Schwartz is investigating the impact of artificial sweeteners and antidiabetica on the intestinal microflora of aquatic animals.

Even if some effects of these so called “wealth chemicals” on human beings are already demonstrated, their influence on aquatic biocoenosis and the ecosystem remains largely unknown. It is shown, however, that wealth chemicals have adverse effects on the intestinal flora of humans and could thereby trigger diseases. Based on these findings and using modern methods of molecular biology, the researcher team at the KIT-IFG is studying the influence of artificial sweeteners and antidiabetics on the intestinal flora of fishes and mollusks.

The substances mentioned are suspected of changing the composition of microbiomes of aquatic animals, thereby causing diseases. Specific changes in the composition of the microbiome are correlated with vitality markers of the organisms studied to point out possible risks for the organisms as well as the aquatic ecosystem.
