Photoprotection in marine Antarctic ecosystems

Antarctic marine organisms are expected to contain some photoprotective compounds for UV-avoidance. These compounds are likely to appear in different relative concentrations depending on the light exposure and pigmentation of the marine organism. It is further likely that compound production varies under diverse microbiome conditions. Some of these compounds will be isolated and tested in a cosmeceutical pipeline for the development of skin care UV-protective products. I am honoured to participate in this Antarctic expedition to perform related experiments in February 2023.

The spanish research base Juan Carlos I is situated on Livingston Island and allows the realization of this project. In outdoor aquaria we are investigating the response of an antarctic sponge and ascidian species to microbiome distress and UV exposure.
