Thermophilic bacterium isolated from the basaltic subsurface of the volcanic island Surtsey

A team lead by Matís’ microorganisms researchers and specialists has recently published a research article in the International Journal of Systematic and Evolutionary Microbiology. The article is called: Rhodothermus bifroesti sp. nov., a thermophilic bacterium isolated from the basaltic subsurface of the volcanic island Surtsey.

The volcanic island Surtsey is the southernmost point of Iceland and it was formed in volcanic eruptions that took place from 1963 to 1967. Surtsey has been protected from human interference since it was formed but has been a subject for many scientific researchers.

The Article was published online late January 2022 and the abstract is as follows:

Novel thermophilic heterotrophic bacteria were isolated from the subsurface of the volcanic island Surtsey off the south coast of Iceland. The strains were isolated from tephra core and borehole fluid samples collected below 70 m depth. The Gram-negative bacteria were rod-shaped (0.3–0.4 µm wide, 1.5–7 µm long), aerobic, non-sporulating and non-motile. Optimal growth was observed at 70 °C, at pH 7–7.5 and with 1% NaCl. Phylogenetic analysis identified the strains as members of the genus Rhodothermus . The type strain, ISCAR-7401T, was genetically distinct from its closest relatives Rhodothermus marinus DSM 4252T and Rhodothermus profundi PRI 2902T based on 16S rRNA gene sequence similarity (95.81 and 96.01%, respectively), genomic average nucleotide identity (73.73 and 72.61%, respectively) and digital DNA–DNA hybridization (17.6 and 16.9%, respectively). The major fatty acids of ISCAR-7401T were iso-C17:0, anteiso-C15:0, anteiso-C17:0 and iso-C15:0 (>10 %). The major isoprenoid quinone was MK-7 while phosphatidylethanolamine, diphosphatidylglycerol, an unidentified aminophospholipid and a phospholipid were the predominant polar lipid components. Based on comparative chemotaxonomic, genomic and phylogenetic analyses, we propose that the isolated strain represents a novel species of the genus Rhodothermus with the name Rhodothermus bifroesti sp. nov. The type strain is ISCAR-7401T (=DSM 112103T=CIP 111906T).

An original research article on Basalt-Hosted Microbial Communities in the Subsurface of the Young Volcanic Island of Surtsey, Iceland


Pauline Bergsten

Ph.D. nemi

A team of Matís scientists, in partnership with the University of Iceland and the University of Utah, has recently published a new original research article called „Basalt-Hosted Microbial Communities in the Subsurface of the Young Volcanic Island of Surtsey, Iceland“. The article appeared in Frontiers in Microbiology.

The team consisted of five scientists from Matís’ Microbiology research group; Pauline Bergsten, Pauline Vannier, Alexandra María Klonowski, Stephen Knobloch and Viggó Marteinsson and they wrote the article along with Magnús Tumi Gudmundsson from the university of Iceland and Marie Dolores Jackson from the University of Utah.

The abstract of the article is here below and you can read the full text here:

Basalt-Hosted Microbial Communities in the Subsurface of the Young Volcanic Island of Surtsey, Iceland

The island of Surtsey was formed in 1963–1967 on the offshore Icelandic volcanic rift zone. It offers a unique opportunity to study the subsurface biosphere in newly formed oceanic crust and an associated hydrothermal-seawater system, whose maximum temperature is currently above 120°C at about 100 m below surface. Here, we present new insights into the diversity, distribution, and abundance of microorganisms in the subsurface of the island, 50 years after its creation. Samples, including basaltic tuff drill cores and associated fluids acquired at successive depths as well as surface fumes from fumaroles, were collected during expedition 5059 of the International Continental Scientific Drilling Program specifically designed to collect microbiological samples. Results of this microbial survey are investigated with 16S rRNA gene amplicon sequencing and scanning electron microscopy. To distinguish endemic microbial taxa of subsurface rocks from potential contaminants present in the drilling fluid, we use both methodological and computational strategies. Our 16S rRNA gene analysis results expose diverse and distinct microbial communities in the drill cores and the borehole fluid samples, which harbor thermophiles in high abundance. Whereas some taxonomic lineages detected across these habitats remain uncharacterized (e.g., Acetothermiia, Ammonifexales), our results highlight potential residents of the subsurface that could be identified at lower taxonomic rank such as Thermaerobacter, BRH-c8a (Desulfallas-Sporotomaculum), Thioalkalimicrobium, and Sulfurospirillum. Microscopy images reveal possible biotic structures attached to the basaltic substrate. Finally, microbial colonization of the newly formed basaltic crust and the metabolic potential are discussed on the basis of the data.

School on Adding Value to Food Side Streams


Eva Margrét Jónudóttir


Matís, The University of Iceland and Institute of animal reproduction and food research (Polish academy of sciences) in Olsztyn are planning a 10-day course coached by professional tutors on adding value to food side streams. The Course will take place in Iceland, October 7-17, 2021.

The School on Adding Value to Food Side Streams will recruit talented students and young researchers to improve their entrepreneurial and managerial skills to solve complex challenges and enhance innovation.

  • Increase awareness: On social and environmental responsibility of food producers. And on ideas and opportunities on improving food side streams utilization
  • Building ideas: Team up with students and young professionals with diverse backgrounds and face the opportunities and challenges associated with valorisation of side streams in the food industry.
  • Concepts and Products Development: Apply venture creation methodology to develop new food concepts, products and start-up businesses.
  • Networking: Experience the melting pot of ideas with students and young entrepreneurs Soft skills and entrepreneurship training: Improve your entrepreneurial and managerial skills to solve complex multidisciplinary challenges and enhance innovation.


Further information:

The Innovation, business creation and valorization of side streams of food production and food processing Bilateral Initiative benefits from Iceland, Liechtenstein and Norway through the EEA and Norway Grants. The aim of the project is to establish cooperation between institutions as well as improve the entrepreneurial culture, confidence and skills of graduate students and young scientists in Poland with a focus on the valorization of side streams in food production and food processing.

The EEA and Norway Grants represent the contribution of Iceland, Liechtenstein and Norway towards a green, competitive and inclusive Europe.

There are two overall objectives: reduction of economic and social disparities in Europe, and to strengthen bilateral relations between the donor countries and 15 EU countries in Central and Southern Europe and the Baltics. The three donor countries cooperate closely with the EU through the Agreement on the European Economic Area (EEA). The donors have provided €3.3 billion through consecutive grant schemes between 1994 and 2014.

For the period 2014-2021, the EEA and Norway Grants amount to €2.8 billion.

The EEA and Norway Grants scheme consists of two financial mechanisms. The EEA Grants are jointly financed by Iceland, Liechtenstein and Norway, whose contributions are based on their GDP. Norway Grants are financed solely by Norway.

The Nordic Salmon Workshop


Gunnar Þórðarson


A workshop on salmon farming will be held on October 27 at Ölvus Cluster, Hafnarberg 1, 815 Þorlákshöfn.

The meeting starts at 08:30 and ends at 17:00 the same day.

The workshop subjects:

  1. Salmon feed: new sources and optimal composition for different environments
  2. New development in sea- and salmon louse
  3. Production of large smolts in hatcheries
  1. Salmon feed will be a very dynamic area of research and development in the future. With feed requirements of salmon growing in extreme environmental conditions, such as low temperature, are not fully understood. Furthermore, technical solution to minimize movements of fish in sea cage during the coldest periods in winter could improve conditions of fish during the coldest months
  2. Several options already exist for chemically treating salmon lice in sea cages. However, there are two main problems associated with treating lice in such a way. Firstly, there are negative environmental impacts and secondly, lice can and have developed resistance to many of the available chemicals currently being used
  3. There has been a growing interest in land-based salmon farming under more controlled environment. Large smolt farming is a land-based farming, with longer growing time ashore and shorter in ONP, reducing risk in farming with higher cost. Reducing lead time in sea also enables producers to reduce the spread in biomass throughout the year. This may be one of the most sustainable ways of maximizing utilization of licenses.

The meeting is open for anybody interested in salmon farming. Included are refreshment at the meeting and reception at Lax-inn in Reykjavík after the meeting. The cost is ISL 3.000.

The meeting will be in English, and registrations will be open on the home page soon.

An International Conference on The External Dimension of the Common Fisheries Policy

A conference focusing on the external dimension of the common fisheries policy was held within the framework of the FarFish project in beginning of June 2021. The aim of the conference was to review the implementation of the External Dimension of the CFP and to provide recommendations ahead of the next revision of the CFP.

The conference was attended by high-level experts and key stakeholders from the fishing industry and NGO sectors, together with relevant policy makers, scientists and academics, which contributed to discussions on the importance, advantages and challenges of the EU role in international fisheries management and ocean governance.

The conference spanned over two days, with the first day consisting of presentations and panel discussions from high-level experts; and the second day was more in the form of a workshop where different experts and stakeholders “dug deep” into how to improve management under fisheries agreements.

Recordings from the conference are now available on the FarFish website, along with a summary leaflet and main conclusions from day 1 and day 2.
