Fucus vesiculosus extracts that have both radical scavenging activity and metal chelating ability in vitro were used as natural antioxidant in granola bars enriched with fish oil emulsion by using primary and secondary emulsion systems stabilized by sodium caseinate alone and sodium caseinate – chitosan. The bars were stored at 20 ° C and evaluated over a period of 10 weeks by measuring the development of primary and secondary oxidation products. The samples prepared with secondary emulsion system developed less oxidation products probably due to increased interfacial layer thickness that would act as a barrier to the penetration and diffusion of molecular species that promote oxidation. The positive charge of oil droplets in the secondary emulsion may also inhibit iron – lipid interaction through electrostatic repulsion. Additional protection against lipid oxidation was obtained when fish oil emulsions were added to the granola bars especially in combination with acetone and ethanol extracts of Fucus vesiculosus.

The drying characteristics and lipid oxidation in brined and blanched whole capelin were studied during controlled low temperature drying to establish the influence of lipid content and blanching. Drying characteristics (moisture content, drying rate and water activity) and lipid oxidation indicators (PV, TBARS and color) were determined. Drying was influenced by blanching as well as the lipid level. Moisture content at equilibrium for brined and blanched high lipid dried capelin was 20 and 13% (aw, 0.69 and 0.62), whereas counterpart low lipid groups had 19 and 11% (Aw, 0.67 and 0.59) accordingly after 184 h of drying. Changes in PV, TBARS and color were observed as drying progressed with brined capelin exhibiting more stability in the attributes than blanched capelin. Blanched and low lipid capelin dried faster; however, blanching resulted in increased yellowness color making it unpopular for capelin drying.
A novel hyperthermophilic, piezophilic, anaerobic archaeon, designated NCB100T, was isolated from a hydrothermal vent flange fragment collected in the Guaymas basin at the hydrothermal vent site named 'Rebecca's Roost' at a depth of 1997 m. Enrichment and isolation were performed at 100 ° C under atmospheric pressure. Cells of strain NCB100T were highly motile, irregular cocci with a diameter of ~ 1 µm. Growth was recorded at temperatures between 70 and 112 ° C (optimum 105 ° C) and hydrostatic pressures of 0.1–80 MPa (optimum 40–50 MPa). Growth was observed at pH 3.5–8.5 (optimum pH 7) and with 1.5–7 % NaCl (optimum at 2.5–3 %). Strain NCB100T was a strictly anaerobic chemo-organoheterotroph and grew on complex proteinaceous substrates such as yeast extract, peptone and tryptone, as well as on glycogen and starch. Elemental sulfur was required for growth and was reduced to hydrogen sulfide. The fermentation products from complex proteinaceous substrates were CO2 and H2. The G + C content of the genomic DNA was 41.3 %. Phylogenetic analysis of the 16S rRNA gene sequence revealed that strain NCB100T belongs to the genus Pyrococcus, showing 99 % similarity with the other described species of the genus Pyrococcus. On the basis of physiological characteristics, DNA G + C content, similarity level between ribosomal proteins and an average nucleotide identity value of 79 %, strain NCB100T represents a novel species for which the name Pyrococcus kukulkanii sp. nov. is proposed. The type strain is NCB100T (= DSM 101590T= Souchothèque de Bretagne BG1337T).
Research on thermophilic microorganisms in high-temperature areas in Reykjanes, Hengill area and Fremrinámur. Prepared for Expert Group 1 in Framework Plan 3 / Thermophilic microorganisms from geothermal areas at Reykjanes, Hengill and Fremrinámar.
The current study was carried out under the auspices of Framework Plan 3 and included high-temperature areas that declined in the waiting category in RÁ2. The areas were Trölladyngja and Austurengjahver in Reykjanes, Fremrinámar and Þverárdalur and Innstidalur in the Hengill area. The aim of the study was to assess the diversity and rarity of thermophilic microorganisms in the above areas. The methodology was based on DNA analysis independent of culture. DNA was isolated from samples and species-identifying genes amplified and sequenced and the sequences compared to sequences in gene banks and from previous studies. A total of 118 samples were collected in 2015 and were able to be sequenced approx. Their 59%. A total of 10 million 16S gene sequences were obtained from sequencing, which dropped to almost six million after all quality and length conditions had been met. Most rows were obtained from Innstadalur, or 2,176,174, but fewest 286,039 from Trölladyngja. The diversity of microorganisms in each region was assessed by comparing the number of arrays, number of species, collection curves, and Shannon's diversity coefficient. The total number of samples and sequences of each area was very different and reflect its diversity. When the series were classified as species with 97% matching, it was found that most species came from Þverárdalur, or about 42 thousand, but the fewest from Trölladyngja, or about 9 thousand. More than 12 thousand species were found in samples from Fremrinámur, which came as a surprise as the area and the samples seemed homogeneous and such diversity was not expected. All major thermal bacteria were found in the samples, both Ancient Bacteria and Bacteria. Special groups were found especially within the Thaumarchaeota faction. The assessment of diversity in individual areas with collection curves and diversity coefficient was based on the smallest number of rows or 286,039 from Trölladyngja. The greatest diversity of species was in Þverárdalur and Innstadalur and the least at Trölladyngja and Austurengjahver, but Fremrinámar was in between. Collection curves gave the same result. Biodiversity (H) gave a different ranking. There were Þverárdalur and Fremrinámar with the most diversity (H = 8 and 7.7), then Innstidalur but Trölladyngja and Austurengjahver (H = 6) ran the train. Rarity was assessed on the basis of the number and proportion of unknown species in comparison with the Silva database. The number of unknown species was greatest in Þverárdalur and Innstadalur, both with over 1000, Fremrinámar with 756 and Trölladyngja and Austurengjahver with over four hundred unknown species. National rarity was assessed by comparing data from individual regions in previous studies and examining whether a match occurred. It turned out that the geothermal area in Fremrinámur contains a large number of species that have no equivalent in other thermal areas.
The current project was requested by the Master Plan for Nature Protection and Energy Utilization and aimed at geothermal areas which had not been classified for preservation or utilization during Masterplan 2. The geothermal areas investigated were Trölladyngja and Austurengjahver at Reykjanes, Fremrinámar and Þverárdalur and Innstidalur at Hengill. The goal of the project was to estimate biodiversity and rarity of thermophiles inhabiting the areas mentioned. The methods used were DNA based and were performed on DNA extracted from primary samples (culture independent). Microbial species identification was performed by amplification and sequencing of 16S rRNA genes and comparison with sequence databases and previous research. A total of 118 samples were collected in 2015 of which 59% were sequenced. The total sequencing yield was 10 million reads, of which 6 million passed quality assessment and were used for downstream analyzes. The largest proportion of the reads were obtained from Innstidalur samples, 2,176,174 reads, and the lowest proportion from Trölladyngja, 286,036 reads. The biodiversity of microorganisms within each area was estimated using the number of phyla and species, rarefaction curves and Shannons' biodiversity index. The total number of species identified varied between sites and reflected the diversity of the geothermal area and the total amount of sequences obtained. Using a cut-off value of 97% similarity, the sequences were classified to the species level. The highest number of species, approximately 42.000, were identified in samples from Þverárdalur and the lowest number, approximately 9.000, in samples from Trölladyngja. Roughly 12,000 species were found in samples from Fremrinámar, which was surprising as the area and the samples appeared rather homogenous and such diversity was therefore not expected. All the main thermophilic taxa of the Bacteria and Archaea domains were identified in the samples. Unknown groups were found especially within the phylum of Thaumarchaeota. For the rarefaction and biodiversity index estimates the lowest number of sequence reads, Trölladyngja, was used as reference. The species diversity was found to be highest in Þverárdalur and Innstidalur, the lowest in Trölladyngja and Austurengjahver, and intermediate in Fremrinámar. Rarefaction curves showed the same results. The calculated biodiversity index (H) gave different results, indicating highest diversity in Þverárdalur and Fremrinámar (H = 8 and 7,7 respectively), intermediate in Innstidalur (H = 7.0) and lowest in Trölladyngja and Austurengjahver (H = 6). Rarity was estimated as the number of species which could not be identified by comparison to the Silva database. The highest number of unidentified species was roughly 1000 in Þverárdalur and Innstidalur, 756 in Fremrinámar and between 300- 400 in Trölladyngja and Austurengjahver. The rarity was also estimated by comparing data obtained in the current project with data from previous projects. The analysis revealed a particularly high number of unique species in Fremrinámar that have not been identified in other geothermal areas in Iceland.

Northern Cereals - New Opportunities
A project on grain farming in the Arctic was carried out between 2013 and 2015. The project was funded by the Nordic-Atlantic Co-operation (NORA). Participants came from Iceland, Northern Norway, the Faroe Islands, Greenland, Orkney and Newfoundland. The purpose of the project was to support grain farming in sparsely populated Nordic areas by testing different barley crops and providing guidelines for farmers and food companies. The most promising barley crops (Kría, Tiril, Saana, Bere, NL) were tested with all participants and measurements were made on yield and quality. The amount of barley harvest varied between regions and years. The average starch content of dried grain was 58%, which is sufficient for the baking industry. Fungal toxins (Mycotoxin) were not detected in the samples sent for analysis. It was concluded that early grain sowing was the most important factor in promoting a good grain harvest in the NORA area. Unit is important to cut the grain early to prevent losses due to storms and birds.
A project on the cultivation of cereals in the North Atlantic Region was carried out in the period 2013 to 2015. The project was supported by the Nordic Atlantic Cooperation (NORA). Partners came from Iceland, NNorway, Faroe Islands, Greenland, Orkney and Newfoundland. The purpose of the project was to support cereal cultivation in rural northern regions by testing barley varieties and providing guidelines for farmers and industry. The most promising barley varieties (Kria, Tiril, Saana, Bere and NL) were tested in all partner regions for growth and quality characteristics. Grain yields were very variable across the region and differed between years. Average starch content of grain was about 58% which is sufficient for the baking industry. Mycotoxins, toxins formed by certain species of mold, were not detected in selected samples. Early sowing was concluded to be the most important factor for a successful cereal production in the North Atlantic region. Early harvest is recommended in order to secure the harvest before it becomes vulnerable to wind and bird damages, even though the grain will be slightly less mature.
