Greetings from our PhD-student Pierrick

Blog post by Pierrick Stévant

 

As part of WP2’s research plan, Pierrick Stévant (Møreforsking) travelled (home) to CEVA in Brittany for the second consecutive year to conduct practical experiments in collaboration with Hélène Marfaing. These experiments are focusing on (i) seaweed storage post-harvest and (ii) removal of undesirable compounds.

During these two weeks of (intense) work Pierrick and Hélène tested both cold storage and seawater storage of dulse (P. palmata), ensiling of sugar kelp (S. latissima) and cadmium desorption of winged kelp (A. esculenta) in salt water baths. The biomass used in these experiments were either hand-harvested from shore near the CEVA (P. palmata) or cultivated (A. esculenta, S. latissima).

Many samples were taken throughout the different treatments which will be analyzed for their biochemical content, involving other PROMAC partners.

Workshop – Seaweed for dummies

Blog post by Annelise Chapman

Seaweed sex, chemical defense mechanisms of the sugar kelp and how seaweeds may be integrated in sustainable value chains, were among the many subjects discussed during a PROMAC workshop entitled ‘Seaweeds for Dummies’ which took place on May 25 at Møreforsking Ålesund.

Following an initiative from PROMAC partners who are experts in economics and logistics, but know little about seaweeds as organisms and their potential uses, Møreforsking Ålesund researchers Annelise Chapman and Pierrick Stévant hosted the workshop, which was also attended by some of our industry partners.

“A useful, interesting and constructive day“, was the general verdict, and the event may be a model for a similar workshop with focus on value chains and logistics in the fall – or: ‘Dummy no more’!
