Toxicological tests for secondary metabolites produced by cultivated Arctic diatoms

Awarded: NOK 73,000

UiT The Arctic University of Tromsø is currently cultivating marine micro algae in large scale bioreactors by using CO2 in flue gases from a local ferrosilicon plant. In order to monitor to content of potential toxic metabolites in the algae cultures, we want to study if culture extracts have any effects on the transriptomes of sea urchins. This assay is established at Observatoire Océanologique de Banyuls in France. To monitor survival of sea urchin embryos is a quite course bioassay, while responses on gene expression on stress-response genes might reveal more subtle toxic effects. In this project we want to test the concept on one species, and if successful we will establish a larger scale project for monitoring diatoms cultivated in the large scale bioreactors in Tromsø.
