Polar diatom microalgae synthesize metabolites, some of them unique, that are of growing interest for human health uses and blue biotechnology applications in the Nordic countries, and beyond. Due to their chemodiversity with a broad spectrum of bioactivities, polar diatoms are a unique yet largely underestimated emerging bioressource, because they are invisible and difficult to access. The Arctic Ocean is the most impacted by ongoing climate change; its many effects are having a negative impact on diatoms and their metabolites. The decrease/loss of this bio-/chemodiversity is a major issue in the protection of the polar marine biome. Currently, environmental and sea protection laws are not adapted to the protection of marine microorganisms. The transdisciplinary framework of this project, combining biology and law sciences, proposes to explore in parallel 1) the bioactivities of metabolites synthesized by Arctic diatoms; 2) new legal strategies to protect the bio-/chemodiversity of Arctic diatoms.
