Hundreds of European students wanted to come to Iceland!

Well over four hundred foreign students applied to attend courses in Iceland!

From March 10 to 18, an international course will be held in Iceland under the auspices of BEST in Iceland. BEST (Board of European Students of Technology) is a European association of university students in technology.

A total of 81 European universities in 30 countries are members of the association, but an Icelandic member association was founded by students at the University of Iceland in 2005. The main purpose of BEST is to offer students at member universities additional education in the form of short courses as well as giving students the opportunity to learn languages of other nations.

The course that will be held in Iceland next week is entitled “Eat that! Innovation in food technology and nutrition "and is run by BEST in close collaboration with Matís (www.matis.is) and the University of Iceland, in addition to which Reykjavík University, Landspítali University Hospital, Marel and Lýsi are involved in the project.

The course will cover "nutrition in innovation" from A to Z. During the week-long stay, the European students will listen to lectures by professors at the University of Iceland, Matís employees and working engineers, visit Icelandic companies and visit field guards. The students will also visit Gullfoss and Geysir and Jökulsárlón, among other places.

It should be noted that the students who found out in this course only have to pay for part of the fare to and from the country, but a grant was received from Europe in Youth for all other costs of the course for each participant.

There was great interest in the course, with a total of four hundred European university students applying. As the number of participants was limited, only 22 came to Iceland on this occasion. The number of applications shows that there is a great deal of interest among educated European young people to learn from Icelanders about food and nutrition as well as to get to know a country and a nation.

Please contact the President of BEST in Iceland for further information and interviews.

Microbial diversity in hot springs in Vonarskarð / Microbial diversity in hot springs in Vonarskarð

Samples were taken in the geothermal area east of Eggja in Vonarskarð. A total of 32 samples were taken from different hot springs, streams and soils at different temperatures and acidity levels. Elements were measured in several water samples. The species composition of bacteria and ancient bacteria was determined by molecular biological methods. A total of 1052 16S rRNA gene sequences of bacteria were detected, spreading across 23 factions. More than 50 new bacterial species were found in the samples, of which 11 are probably representatives of new genera. The genome of ancient bacteria was 155 in number. Ten new species of ancient bacteria were found, including five representatives of new genera. The ecosystem of the geothermal area as a whole must therefore be considered very special. The most common were the primitive species of the array Aquificae. Primitive and non-primitive Proteobacteria species were found in significant quantities and were both known and new species. Typical species of bluish-green bacteria and Chloroflexi were found in the samples. Firmicutes, Bacteroidetes and Chlorobi species were found mainly in samples taken at lower temperatures. Ancient bacteria found in the samples were spread over two largest groups of ancient bacteria, i.e. Crenarcheota and Euryarchaeota. The biological diversity of bacteria and archaeal bacteria in the samples was most often in the range Nt / Nmax = 1.0 -3.0, which is typical of peripheral ecosystems. In some cases it was higher, especially in samples where the temperature was relatively low and therefore more viable for more species. Seven bacterial species were cultured from the samples, including one new species of the genus Sediminibacter from the Bacteroidetes class. Several Thermus species were bred, including T.islandicus which is native to Iceland. The proteobacteria Thermomonas hydrothermalis and Tepidimonas ignava were also grown from several samples and the thermophilic Firmicutes species Anoxybacillus kualawohkensis.

Samples were taken from the geothermal area east of Eggja in Vonarskarð. A total of 32 samples were collected from different sites at various temperature and pH values. The concentration of 72 elements were estimated in water samples. Species composition of Bacteria and Archaea was estimated using molecular methods. A total of 1052 16S rRNA gene sequences belonging to 23 bacterial phyla were detected. Roughly 50 novel bacterial species were found of which 11 represent new genera. Ten novel archaeal species were found, five of which represent new genera. Species belonging to the autotrophic phylum of Aquificae dominated many samples. Species of different subphyla of Proteobacteria were also represented in high ratios in the samples, both described and novel species. Common species of Cyanobacteria and Chloroflexi were also detected. Species of the Firmicutes, Bacteroidetes and Chlorobi phyla were common in samples taken at lower temperatures. Archaeal species in the samples belonged to both Crenarchaeota and Euryarchaeota. The calculated biodiversity index for bacteria and archaea in the samples was 1,0-3,0 which is in concordance with values obtained for extreme ecosystems. It was higher in a few samples which were taken at lower temperatures and thus represent habitats acceptable for more diverse organisms. Seven bacterial species were isolated from the samples. One of these represents a novel species of the genus Sediminibacter within the phylum of Bacteroidetes. Several Thermus species were cultivated, ie T.islandicus which has so far only been found in Iceland. The Proteobacteria species Themomonas hydrothermalis and Tepidimonas ignava were also isolated as well as a thermophilic Firmicutes species, Anoxybacillus kualawohkensis.

Production of wheeled animals for cod farming / Production of quality rotators for breeding cod fry

Production of wheeled animals for cod farming / Production of quality rotators for breeding cod fry

There is great interest in finding ways to control farming conditions at all stages of aquaculture. The control of microbial flora in the environment and the gastrointestinal tract of larvae is, among other things, thought to be able to reduce losses that occur in the early stages of marine fish farming. A large number of bacteria usually accompanies feed animals in cod farming, but the use of recycling systems in the breeding of equidae has, among other things, the advantage that a smaller number of bacteria gain a foothold in the systems compared to batch farming. The use of bacterial flora for bacterial flora control has increased significantly in recent years and has in some cases contributed to increased growth and quality of larvae. In addition to strengthening co-operation between cod juvenile producers in the Nordic countries, the aim of the project is to develop methods that increase stability and efficiency in the production of feed animals. It is based on a recycling system designed by Sintef in Norway and this section investigates the effects and presence of selected beneficial bacteria in the system. The main results of treatment with two selected bacterial strains showed that the wheeled animals tolerated the treatment well and an increased crop of animals was obtained when treated with the bacteria in lyophilized form. There was a significant decrease in the number of bacteria in the purgatory during treatment with liquid bacterial culture and the number of bacteria in the purgatory did not reach the initial number during the experiment, but there was some increase in the number of lactic acid bacteria. Although the amount of lactic acid bacteria in equidae only increased after treatment, the bacterial strains did not gain a foothold in the system or lead to changes in the composition of the bacterial flora when treated at this concentration. The project is funded by Nordisk Atlantsamarbejde (NORA) and worked in collaboration with Matís, the Marine Research Institute, SINTEF, Fiskaaling, IceCod and Stofnfisk as well as Nordland Marin Yngel.

There is an increasing interest in controlling environmental parameters during the first production stages of aquaculture and controlling bacterial numbers is among various environmental parameters that are believed to promote increased survival of larvae. Elevated bacterial numbers are introduced into the system through the live feed, but numbers of bacteria have been found to be greatly reduced by the use of recirculation culturing system as compared with batch culturing systems. Furthermore, the use of potentially probiotic bacteria in aquaculture has increased over the past years and has in some cases contributed to increased growth and quality of marine larvae. In addition to promoting collaboration between cod producers within the Nordic countries, the main goal of the current project is to develop methods for stable and advantageous production of live feed animals (rotifers). The project is based on a recirculation culturing system engineered by SINTEF and the present part of the project deals with the effect of treatment and persistence of selected probiotic bacterial strains in the system. The overall results indicate that the rotifer cultures were not negatively affected by the bacterial treatment and treatment using freeze-dried preparations of the two probiotic strains even resulted in improved harvesting of the live feed. A drop in bacterial numbers within the bio-filter unit was, however, observed following the addition of liquid bacterial cultures, indicating negative effects of the bacteria on the bacterial community of the bio-filter unit. An increase in the numbers of lactic acid bacteria was observed in the rotifer cultures following treatment, but the probiotic bacterial strains were neither found to become established as a part of nor affect the dominating bacterial community of the system using the concentrations applied. The project was supported by the Nordisk Atlantsamarbejde (NORA) and is a collaboration between Matís, Hafrannsóknastofnun, SINTEF, Fiskaaling, IceCod, Stofnfiskur and Nordland Marin Yngel.

Summary of previous research on capelin roe - Matís report

A new report has been published by Matís. The report is a summary of previous research on capelin roe.

In recent years and decades, various measurements and research on capelin roe in Iceland have been carried out at Matís ohf / Rannsóknastofnun fiskiðnaðarins. This is primarily a study of microorganisms, egg filling and water content. The report will cover microbial research carried out during the 1984 season, microbiological measurements in the period 2000-2008 and measurements of water content and egg filling 1984-2008.

The information that can be found there is exciting and relevant these days, as people are talking about the importance of capelin for the country's economy.

The full report can be found here.

Hrönn Ólína Jörundsdóttir is defending her doctoral dissertation in environmental chemistry

Matís' employee, Hrönn Ólína Jörundsdóttir, defended her doctoral dissertation "Temporal and spatial trends of organohalogens in guillemot (Uria algae) in North Western Europe" on February 6, 2009 at Umildfild Stockholm University.

The dissertation deals extensively with persistent organic pollutants in the Nordic countries, such as PCBs and the insecticide DDT, as well as their metabolites, which were mainly measured in long-range eggs. The substances were measured in eggs from Iceland, the Faroe Islands, Norway and Sweden to obtain a geographical comparison.

The results show that the North Atlantic ecosystem is less polluted than the Baltic ecosystem, but various pollutants were found to be in similar concentrations in these areas and it is necessary to investigate further why this is the case. Fluorinated alkanes, which come from outdoor clothing, have recently been found in significant amounts in nature, measured in long-tailed eggs from Iceland, the Faroe Islands, Norway and Sweden and were in some cases in higher concentrations in eggs from the North Atlantic than in the Baltic Sea. Brominated fire retardants, which are used in electronics, among other things, were measurable everywhere and it seems that it is possible to identify the different origins of the substances that reach the North Atlantic, on the one hand from North America and on the other from Europe.

A comparison was also made of the amount of pollutants in seven Icelandic bird species, i.e. heron, eider, osprey, elephant, herring gull, black-backed gull and skimmer. The foam was found to have a significant high concentration of pollutants, including PCB compounds and the insecticide DDT, and it is important to study the health condition of the foam.

It is clear that part of the pollution measured in the Icelandic ecosystem travels through ocean and air currents to Iceland, but on the other hand a significant part is due to Icelanders' use of goods that contain various pollutants.

Supervisors were dr. Åke Bergman Professor of Environmental Chemistry at Stockholm University, dr. Professor Anders Bignert, Swedish Museum of Natural History and dr. Mats Olsson Professor Emeritus. The opponent was Dr. Derek Muir, Environment Canada.

The examination committee consisted of dr. Kristín Ólafsdóttir, Associate Professor at the University of Iceland, dr. Björn Brunström, professor at Uppsala University and dr. Conny Östman, Associate Professor at Stockholm University.

The project "Bætibakteríur - the other side" was one of the projects that was nominated for the Innovation Award of the President of Iceland in 2009.

The project was funded by the Student Innovation Fund in the summer of 2008 and was carried out by Hugrún Lísa Heimisdóttir, a student who had completed her first year in biotechnology in the field of resources at the University of Akureyri. The student's project was part of a larger project, “Bætibakteríur í lúðueldi”, which was carried out in collaboration with Matís ohf., The University of Akureyri, Fiskey hf and the University of Hólar with a grant from the Technology Development Fund (2006-2008).

The aim of the project as a whole was to look for possible beneficial bacteria in the halibut farming of Fiskey hf. and which could then be added to the environment of halibut larvae for the purpose of improving the growth and performance of the larvae.

The first few weeks are the main bottleneck in halibut farming and other marine fish, but then the larvae feed on live feed animals. The forage animals carry a large number of bacteria and the larvae at this stage of development need to rely solely on a non-specific immune response. There is therefore great interest in the use of supplementary bacteria in the aim of controlling the composition of bacterial flora in the environment and gastrointestinal tract of larvae and making it more positive for the larvae.

Treatment with a mixture of three types of potential beneficial bacteria turned out to give significantly better results to halibut larvae in the early stages of rearing, and in the student's project the focus was therefore on the other side of the beneficial bacteria, ie. the aspect of the bacterial properties that can be studied and measured in the laboratory. One of the characteristics of powerful supplemental bacteria is to inhibit the growth of unwanted bacteria and the student researched this and various other properties of the bacteria. It is also important to look for cost-effective ways to produce the bacteria in large quantities and store and transport them without losing their properties. Freeze-drying is a convenient and desirable way to store and transport bacteria, and the student examined the growth of the bacteria and their growth-inhibiting effect in both fresh and freeze-dried cultures.

The main results of the project showed that the supplementary bacteria had an inhibitory effect on the growth of dominant bacteria in some samples but little or no effect on the growth of dominant bacteria in other samples. This could indicate that in some larvae the bacterial flora is rich, which has gained a good foothold there and therefore it is difficult to influence the growth of the bacteria. Therefore, it is important to treat with supplemental bacteria early in the breeding process in order for the desired bacteria to gain a foothold there. The results also indicated that the three bacterial strains grow better in the presence of each other than alone.

It can therefore be said that the student's project has shed clear light on the properties of the additive bacteria and the most suitable methods of their production for use in the early stages of halibut farming.

The project was carried out under the guidance of Rannveig Björnsdóttir, lecturer at the University of Akureyri and other experts at Matís ohf. in Akureyri. For further information, contact Rannveig at 422-5108.
