About the speaker:

Madalena is a GreenCoLAB researcher since 2019 based at the company ALGAplus, where she is a PhD student, lab and maternity technician. Madalena has been working with seaweeds for the last six years and now she is mainly focused on the field of biobanking, strain improvement and domestication of novel species. Although her interest for seaweeds is extensive, she is currently dedicated to the cultivation and characterization of Atlantic Nori species.

Company info:

GreenCoLAB - GreenCoLab is a non-profit private organization, a collaborative platform between research and industry, whose research & innovation agenda is based on the exploration of micro- and macroalgae as an essential component for the food, feed, nutraceutical, bioenergy, wastewater and cosmetic industries.

In this presentation we will overview the production of Atlantic Nori and it’s challenges as well as ongoing R&D work towards the selection, improvement and characterization of strains.
