Abstract

Örverur gegna  lykilhlutverki í því að viðhalda heilbrigði og fæðukerfi hafsins og við að stýra næringarefnahringrás hafsins. Við Íslandsstrendur, þar sem heitir Atlantshafsstraumar og kaldir norðurskautsstraumar mætast, myndast einstakt umhverfi og lífríki sjávar. Þó svo að rannsóknir hafi staðið yfir á frumframleiðni frá miðju síðustu aldar með aðstoð smásjáa og gervitunglmynda hafa rannsóknir á flokkunarfræði örvera á umhverfiserfðamengjum í íslenskri lögsögu verið takmarkaðar. Meginmarkmið doktorsrannsóknarinnar var því að skoða hvaða tegundir örvera finnast í íslenskri lögsögu, í hvaða hlutföllum, hvert hlutverk þeirra er í vistríki sjávar og hvaða umhverfisþættir hafa áhrif á dreifingu þeirra.

Meginniðurstöður ritgerðarinnar eru að nauðsynlegt er að kanna örveruflóru hafsins allt árið um kring og einnig mismunandi dýpi. Niðurstöðurnar afhjúpa samhengi örverusamfélaga og umhverfisþátta og leggja grunn að frekari rannsóknum. Opin gögn úr þessari rannsókn mynda viðmið fyrir frekari rannsóknir á vistfræðilegum ferlum og sjálfbærri nýtingu auðlinda hafsins við Ísland á tímum hnattrænna loftslagsbreytinga.

Doctoral defense in food science – Anna Þóra Hrólfsdóttir

Next Friday, November 1, Anna Þóra Hrólfsdóttir will defend her doctoral thesis in food science at the University of Iceland in collaboration with Matís. The thesis is entitled: Improved utilization, preservation and quality of brown algae.

The doctoral defense will take place in the Banquet Hall of the University of Iceland's Main Building from 9:00 a.m. to 12:00 p.m.

Opponents will be dr. Susan Løvstad Holdt, associate professor at the Food Institute of the Danish University of Technology, DTU, and dr. Marthe Jordbrekk Blikra, researcher at the Norwegian food research institute Nofima.

The supervising teacher is María Guðjónsdóttir, and her supervisors are Hildur Inga Sveinsdóttir, assistant professor and expert at Matís, and Sigurjón Arason, professor emeritus and expert at Matís. In addition to them, Ólafur Eysteinn Sigurjónsson, professor, sits on the doctoral committee.

Ólöf Guðný Geirsdóttir, professor and president of the Department of Food and Nutrition, presides over the ceremony, which takes place in the University of Iceland's Festival Hall and starts at 9.00 am.

The following abstract of the essay:
Despite the enormous increase in macroalgae production in recent decades, they are still a relatively underutilized resource in Europe. However, interest in macroalgae has increased significantly in Europe in recent years and it has been predicted that production could increase enormously in the coming decades. With the increased production of macroalgae, it is important to fully utilize, preserve and handle the biomass in an appropriate way to maximize the quality of the product. Therefore, the aim of the study was to investigate and improve the value chains of selected brown algae, with an emphasis on the full utilization of raw materials in the production of flour from kelp, the preservation and shelf life of cultured kelp and marin core, and to evaluate the use of multispectral imaging technology (MSI) to assess the quality of macroalgae within the industry. The results of the study show opportunities in increasing the value of macroalgae through improved production processes. Furthermore, the results suggest that acidification may be suitable as a preservation method for cultured brown algae and that MSI may be used for industrial quality assessment of macroalgae.

Workshop on Catch Quality and Pricing in the Nordic Region

Contact

Sæmundur Elíasson

Project Manager

saemundur.eliasson@matis.is

Thursday November 7th 2024. Held in Ríma conference room in Harpa, Austurbakka 2, 101 Reykjavík. Supported by the Nordic Council of Ministers – Working Group for Fisheries (AG-Fisk).

Workshop description:

The workshop is held to discuss and investigate factors that affect catch quality and pricing, how they interconnect and differ between the Nordic countries. This includes discussions on quality characteristics, how quality parameters currently are and should be measured, regulation frameworks and what affects pricing and market situations. The outcome of the workshop will outline the strengths of different strategies that relate to catch quality within the Nordic region and explore if there are opportunities to implement different methods between regions to achieve higher overall catch quality and value.

Revised suggestions for topics in the workshop agenda are:

  • Price and catch value: What affects the prices? Are they reflected correctly by quality parameters?
  • Quality characteristics: What are the most important quality parameters (handling factors, fish size, condition factor,...)? How do we measure the catch quality parameters? Suggestions for standardization of quality assessment?
  • Fishing methods: How do different fishing strategies and methods affect catch quality?
  • Regulations and legal matters: How do regulations vary between the Nordic countries? How does the regulation work across the countries and are there lessons to be transferred?
  • Market aspects: How do prices differ between direct sales vs auction markets and Vertically integrated company's vs fish market.

Doctoral defense in Chemistry – Rebecca Sim

Next Monday, May 27, Rebecca Sim will defend her doctoral thesis in chemistry at the University of Iceland. The thesis is entitled Distribution of hydrophilic and lipophilic arsenic compounds among macroalgae.

The doctoral defense will take place in the Celebration Hall of the University of Iceland's Main Building at 11:00 a.m. to 1:00 p.m. Opponents will be Dr. Barbro Kollander, senior scientist at the Swedish Food Agency and Dr. Kristmann Gíslason, professional manager of the chemical analysis group at the Icelandic Marine Research Institute. The supervisor is Ásta Heiðrún Pétursdóttir, PhD in chemical analysis and expert at Matís.

The doctoral committee also includes Dr. Guðmundur Haraldsson professor emeritus, dr. Jörg Feldmann, head of the Trace Element Speciation Laboratory (TESLA) at the University of Graz in Austria, and Dr. Karl Gunnarsson, biologist at the Icelandic Marine Research Institute.

The director of defense is Dr. Einar Örn Sveinbjörnsson, dean of the Faculty of Science, University of Iceland.

Rebecca is from North-East Scotland but moved to Iceland in 2020 to study for a PhD. She completed a BSc in Chemistry at the University of Glasgow and an MSc in Analytical Chemistry at the University of Aberdeen. Rebecca currently works as an expert in Matís' chemical analysis group.

The following is an abstract of the essay:
Algae can absorb large amounts of the element arsenic from the sea in the form of inorganic arsenic, which is a known carcinogen. In the algae, arsenic is also detected in the form of diverse organic compounds of arsenic, for example arsenosaccharides and arsenolipids, but organic arsenic species have been considered harmless. However, recent research on arsenolipids has shown that they can be as cytotoxic as inorganic arsenic, and it is possible that arsenosugars have long-term negative effects with regular consumption. There is a lot of mystery about the origin of arsenolipids, but the starting point of their production is believed to take place in algae. Algae are becoming more and more popular in the West. More information on these compounds is urgently needed to fully assess the risks associated with their consumption and to ensure that appropriate regulations are established regarding their maximum levels in food. Samples of red, green and brown algae were collected near Grindavík and Kjalarnes. The samples were thoroughly analyzed for heavy metals and an arsenic analysis was carried out to obtain information on the chemical form of the arsenic. The speciation of arsenolipids is complex and was carried out in selected samples with mass spectrometry HPLC-ICP-M/ESI-MS/MS and HPLC-qToF-MS. In addition, brown macroalgae were divided into biological fractions to determine whether the distribution of arsenic species is uniform throughout the seaweed. Limited information is available globally on algal arsenolipids, so this extensive profiling of them in different species of algae will help elucidate how these enigmatic organic arsenic compounds are formed and where they are stored. The data can also be used for risk assessment of arsenic species in seaweed for human consumption and can therefore influence future food safety legislation.
