A new, interesting project at Matís

At Matís, work is beginning on a project entitled: "New production process for the production of Lútfiskur". The project is funded by the AVS Fisheries Research Fund and will be carried out by Fram Foods, which has a large market share in lye fish in the Nordic countries.

Lute fish is a very special product based on centuries-old methods and we used to preserve raw materials. The raw material is dried down to about 15-16% moisture and there is about 80% utilization loss during drying. The dried raw material is stored until the autumn until processing takes place, which is from the end of September until mid-December. In a conventional processing process, the fillets are soaked, then bent and rinsed, which causes the weight of the fillets to multiply. During bending, the acidity of the product rises a lot and they can therefore absorb a lot of water, which is the explanation for the expansion of the fish during bending. Finally, the fillets are cut into pieces and packed in 1 kg vacuum units. 
 
Some believe that lye fish dates back to the Viking Age, while others believe that lye fish first appeared in the 16th century in the Netherlands and soon found its way to the Nordic countries, where consumption is highest today. The total Nordic market for lye fish is estimated at 5,200 tonnes. Of this, 2,200 tonnes of cod are in Norway, 2,500 tonnes of ling in Sweden and 500 tonnes of ling in Finland. Consumption is traditional and almost exclusively for Christmas, but something is eaten from lye fish at Easter. When consumed, the fish pieces are boiled and served with boiled potatoes, peppers and green beans, not unlike ham. As such, the fish has a very special texture that resembles boiled egg whites and is tasteless after the effect and there is something about flavors such as mustard or bacon being added to the sauce, or as a side dish
 
The idea behind the research project is to seek more flexibility in production by shortening the production time, so that the supermarkets can be offered a fresher product by shortening the processing time.

The project manager is Hörður G. Kristinsson, department manager at Matís.

Matís - Prokaria buys a powerful sequencer from Roche / 454 Life Science

Matís – Prokaria recently acquired a Roche / 454 Life Science sequencer. According to Ragnar Jóhannsson, director of Matís' Biotechnology Division, the device can sequence large amounts of genetic material at once and opens up a new dimension in the search for interesting genes for new enzymes that can be used in the pharmaceutical, food and energy industries. This gene is found in microorganisms that live in hot springs at temperatures of up to 100 degrees and at very different salinity and acidity levels, says Ragnar.

Previously, the so-called Gen-Mining method was used, but the new machine reduces the cost of searching for genes almost 20-fold. But the big plus is that all of the organism's genes that code for all of its hundreds of enzymes are obtained in one go. To put capacity in context, the machine sequences 1,000,000,000 base pairs overnight - the existing machine detects 100,000 base pairs at the same time. This is a 10,000-fold difference in capacity. The new device was purchased in collaboration with the Center for Systems Biology at the University of Iceland and the University of Iceland Experimental Station at Keldur

As mentioned earlier, the device is a FLX type from Roche / 454 Life Science and will be used for various researches and will be used, for example, in research in systems biology, which is about analyzing the overall picture of organisms' activities, ie the interaction of metabolism and gene expression. It is necessary to design production organisms that can carry out complex chemical preparations.

The device will also be used in research on higher animals such as the cod genome, in the search for genetic markers and key genes that control important traits such as growth rate and disease resistance.

The device will also be used in gene expression research, which is important in various health and health research studies, such as cancer research and research into inflammatory diseases. It refers to diseases such as rheumatism, cardiovascular disease.

A major advantage of this device over other comparable devices is that it is possible to sequence the genome of unknown bacteria and even a mixture of genomes, which is important in environmental research. In a new article in Nature, there is an interview with well-known scientists in the field where they state that this is the only device in the world today that can do this.

Volatile compounds suitable for rapid detection as quality indicators of cold smoked salmon (Salmo salar)

Volatile compounds in cold smoked salmon products were identified by gas chromatography to study their suitability for rapid detection as indicators to predict sensory quality evaluated by quantitative descriptive analysis. Smoked salmon odor contributed by guaiacol, boiled potato- and mushroom-like odors characteristic of fish lipid degradation and sweet odors associated with the microbial metabolites 3-methyl-butanal and 3-hydroxybutanone were the most intense odors. Other key volatiles were present in high levels but contributed less to the odors. These included furan-like compounds originating from the smoking, spoilage compounds like ethanol, 3-methyl-1-butanol, 2-butanone, and acetic acid along with oxidatively derived compounds like 1-penten-3-ol, hexanal, nonanal and decanal . Partial least square regression models based on data from storage studies of cold smoked salmon from Iceland and Norway verified that selected key volatile compounds performed better as predictors to explain variation in sensory attributes (smoked, sweet / sour rancid and off odor and flavor) than traditional chemical and microbial variables.

Genetic divergence among East Icelandic and Faroese waters population of Atlantic cod provides evidence for historical imprints at neutral and non-neutral markers

During the past decade, genetic markers have been used increasingly to improve stock discrimination and to aid fisheries management. Today, the Icelandic and Faroese Plateau cod (Gadus morhua) are managed as separate units, belonging to ICES Subareas Va and Vb1, respectively. There is little information on the genetic connectivity of the two units, however, except in terms of tagging experiments which revealed limited adult migration between the two areas, and few genetic studies describing genetic differentiation among Faroese and East Icelandic cod. Here, previously published data on the genetic structure of Icelandic cod were combined with new data from the Faroe Plateau to assess the level and the source of genetic variability of Atlantic cod around the Iceland – Faroe Ridge and the potential sources of genetic variation. In all, 771 cod were genotyped at nine microsatellite loci and at the Pantophysin locus (Pan I). The genetic markers employed were congruent and showed that South Icelandic and East Icelandic – Faroese Plateau populations have limited genetic connectivity. Diversifying selection associated with restricted gene flow is likely to explain the observed pattern with the Pan I locus. Further analyzes detected historical imprints in the microsatellite data, suggesting that the divergence could be due to isolation of different cod populations during the last glacial maximum.

Recolonization history and large-scale dispersal in the open sea: the case study of the North Atlantic cod, Gadus morhua L

Most studies of the genetic structure of Atlantic cod have focused on small geographical scales. In the present study, the genetic structure of cod sampled on spawning grounds in the North Atlantic was examined using eight microsatellite loci and the Pan I locus. A total of 954 cod was collected from nine different regions: the Baltic Sea, the North Sea, the Celtic Sea, the Irish Sea and Icelandic waters during spring 2002 and spring 2003, from Norwegian waters and the Faroe Islands (North and West spawning grounds ) in spring 2003, and from Canadian waters in 1998. Temporal stability among spawning grounds was observed in Icelandic waters and the Celtic Sea, and no significant difference was observed between the samples from the Baltic Sea and between the samples from Faroese waters. F-statistics showed significant differences between most populations and a pattern of isolation-by-distance was described with microsatellite loci. The Pan I locus revealed the presence of two genetically distinguishable basins, the North-west Atlantic composed of the Icelandic and Canadian samples and the North-east Atlantic composed of all other samples. Permutation of allele sizes at each microsatellite locus among allelic states supported a mutational component to the genetic differentiation, indicating a historical origin of the observed variation. Estimation of the time of divergence was approximately 3000 generations, which places the origin of current genetic pattern of cod in the North Atlantic in the late Weichselian (Wisconsinian period), at last glacial maximum.

Resolving species identification problems in the genus Sebastes using nuclear genetic markers

The identification of North Atlantic redfish has been controversial and remains a difficult task due to overlapping of meristic and morphological characters. Here we used nine microsatellite loci to assess the level of genetic differentiation among these species and assess the resolution power of these microsatellite loci for individual assignment-based analyzes. Conventional analyzes as well as individual Bayesian assignment methods clearly separated the four species of North Atlantic redfish as well as the giant form of Sebastes marinus and the so-called “oceanic” and “deep-sea” types of Sebastes mentella. Locus-by-locus analyzes revealed that only five microsatellite loci out of nine used could discriminate the species concerned. The advantage of the Bayesian methods relies in the individual information retrieved. It therefore gave additional information on the interrelationship among species. Indeed, we provide evidence of potential hybridization among species as well as individual misclassification based on morphological identification. We provide a powerful tool to discriminate North Atlantic redfish species, which might be useful for legal issues such as poaching, unintentional harvesting and control label.
