Department of Ecogenetics and Systems Biology - Division of Archaea Biology and Ecogenomics

Go to content

We belong to the Faculty of Life Sciences of the University of Vienna and are part of the Vienna Ecology Centre.
Since April 1, 2013 we are the Archaea Biology and Ecogenomics Division of the Department of Ecogenomics and Systems Biology.


Beside Bacteria, a second evolutionary lineage of microorganisms arose about 3.5 billion years ago on this planet: the Archaea. They thrive in extreme environments reminiscient of conditions on the early Earth, but are also of global ecological importance in moderate common place environments.
It is the main goal of this Department to shed light on fundamental distinctions between archaea and bacteria, to understand their different roles in both ecological and evolutionary processes. We study specifically:
- molecular adaptations and virus defense of hyperthermophilic model organisms
- genome content, expression patterns, physiology and ecology of moderate ammonia oxidizing archaea as well as
- symbioses of microorganisms with viruses and eukaryotes.
We thus attempt to improve the understanding of the role of microorganisms, in particular of archaea, in global biogeochemical cycles and in early evolution.

Christa Schleper on radio Ö1 in this week's series "Vom Leben der Natur"
This week's "Vom Leben der Natur" (un)covers the mysteries of archaea one day at a time for a whole week:
Ob heiße Quellen, Gletscher oder das Tote Meer: Wo es anderen Lebewesen längst zu heiß zu kalt oder zu salzig ist, fühlen sich die Archaea so richtig wohl. Die Mikroorganismen unterscheiden sich unter dem Mikroskop kaum von Bakterien. Doch genetisch haben sie weniger mit Bakterien gemeinsam als der Mensch und der Regenwurm. Sie bilden daher neben Bakterien und den Mehrzellern wie Pilze Pflanzen, Tiere und der Mensch eine dritte Klasse an Lebewesen.
gehören Archaea zu den ältesten Bewohnern der Erde. Ihren Namen verdanken sie dem griechischen Wort archaos, das "uralt" oder "ursprünglich" bedeutet. Früher wurden sie Urbakterien genannt, weil die Bedingungen, unter denen sie leben, jenen ähneln könnten, die zu Beginn des Lebens auf der Erde herrschten. Und noch etwas macht Archaea interessant: Forscher hoffen durch sie das Rätsel um den Ursprung des Lebens zu lösen...

Nature article out on Lokiarchaeota!
Here they come: the closest known relatives of eukaryotes. Of course they are Archaea!The genome of Lokiarchaeum was assembled from a metagenome of cold marine sediments near the hot vent “Loki's castle“ on the mid-Atlantic ridge in 3000 meter depth. It tells us that Lokis might be able to remodel their membrane and form a cytosceleton, as we would expect for an organism that engulfed the endosymbiont...It is now time to culture them!
Congratulations to Anja and Steffen!
Anja Spang, who recently got her PhD in our group and annotated the genome of Lokiarchaeum is one of the first authors, as well as Steffen Jørgensen who pulled them out from the sediments! After long years of research on this archaeal group he was able to pinpoint the right sample for this study! The genome was assembled and analysed in Uppsala (group of Thijs Ettema).

Medial attention for the Nature article!
Austrian newspaper writes "Unser neuer Ahnherr heißt Loki", derStandard announces "Archaeen als nächste Verwandte der höheren Lebewesen identifiziert", Kurier declares "'Geschwister' der höheren Lebewesen entdeckt" and science.ORF reports "Urahn aller höheren Lebewesen gefunden". APA states "Surprise from the Deep Ocean" and APA, Österreich Journal and uni:view Magazin title "Überraschung aus der Tiefsee". - Kaleidoskop der Naturwissenschaft takes up the topic reporting on a "fascinating discovery": "Erste Zwischenstufe in der Evolution von einfachsten zu höheren Lebewesen entdeckt: Lokiarchaea"

Die Ö1 Kinderuni - Radio broadcast with Christa Schleper
Die Ö1 Kinderuni, May 10 2015, 5:10 p.m., " Wozu brauchen wir im Körper Bakterien? Über die Aufgaben der klitzekleinen Lebewesen"
Gestaltung: Barbara Zeithammer
Bakterien haben keinen guten Ruf: Die winzigen Lebewesen gelten als ekelig und ungesund, als gefährliche Krankmacher. Ganz zu Unrecht! Nur wenige Bakterien sind für uns gefährlich, weil sie uns krank machen, sagt Christa Schleper vom Department für Ökogenetik der Universität Wien. Die meisten Bakterien sind lebenswichtig und eigentlich nützliche Freunde unseres Körpers. Sie sind überall, im Wasser, im Boden, auf unserer Haut, in unseren Haaren und vor allem in unserem Darm. Erst langsam beginnen die Wissenschafter/innen zu verstehen, wie wichtig eine gesunde Darmflora ist. Die Bakterien im Darm haben die Forscherinnen und Forscher lange nicht interessiert.

Die Ö1 Kinderuni Reporterinnen Catharina, Jana und Sofanit und ihr Reporterkollege Florian staunen nicht schlecht, als sie erfahren, wie die Darmbakterien uns zu Diensten sind: Sie produzieren zum Beispiel bestimmte Vitamine, helfen unsere Nahrung zu verdauen und ihre Zusammensetzung ist für Gesundheit und Krankheit entscheidend. Jeder Mensch trägt seinen ganz eigenen Mini-Zoo mit sich und auf sich herum und zwar nicht nur viele, sondern auch viele verschiedene Bakterien. Auch in der Tierwelt sind Bakterien unverzichtbare Helfer: Kühe und Koalas können sich nur dank spezieller Bakterien von Gras beziehungsweise den giftigen Eukalyptus-Blättern ernähren... ( OE1)

PNAS paper attracts interest of the media
Microorganisms are key players in emissions of the greenhouse gas (GHG) methane from anoxic carbon-rich peat soils of the Arctic permafrost region. Although available data and modeling suggest a significant temperature-induced increase of GHG emissions from these regions by the end of this century, the controls of and interactions within the underlying microbial networks are largely unknown. This study reveals critical temperatures at which microbial adaptations cause changes in metabolic bottlenecks of anaerobic carbon-degradation pathways and get a lot of medial attention.

The Washington Post writes " The invisible organisms that threaten to make climate change much worse" and The NewScientist warns " Microbes play villainous role in Arctic climate change"
uni:view Magazin titles " Wenn arktischen Mikroben heiß wird" (German only), APA writes about " Arktische Bodenmikroben passen sich schnell Temperaturen an" (German only), ORF announces " Tauende Böden produzieren mehr Methan"

Daily newspaper "Der Standard" writes (28.04.2015)
"Arktische Böden geben weiter viel Methan ab"
Wien – In den Torfböden der Arktis sind mehrere 100 Gigatonnen Kohlenstoff gespeichert, rund die Hälfte des Kohlenstoffs, der sich derzeit in Form von Kohlendioxid in der Atmosphäre befindet. Derzeit tragen diese Böden drei bis zehn Prozent zu den globalen Methanemissionen bei. Was aber passiert, wenn es auch in der Arktis wärmer wird? Das untersuchte ein internationales Forscherteam unter Beteiligung der Uni Wien im Fachjournal PNAS anhand der Analyse von Mikroorganismen in Torfproben aus Spitzbergen. Das Ergebnis: Die Kleinstlebewesen passen
sich sehr schnell unterschiedlichen Temperaturen an und werden auch bei höheren Temperaturen das Treibhausgas Methan mit hoher Effizienz produzieren.

New research review paper in Biotechnology Advances
Microbes capable of producing hydrogen (H) by dark fermentation were often shown to exhibit high volumetric production rates. In this review we focus on recent advances in the isolation of novel phylogenetic groups utilizing formate or CO, the remarkable genetic engineering that enhances H productivity, and the practical implementation of H production. Among the archaeal strains capable of producing H2, Thermococcus onnurineus can be efficiently applied for H production from both, formate and carbon monoxide (CO). T. onnurineus shows the highest volumetric H production rate when grown on formate.

Two new papers about microbes in permafrost soils published

Congratulations to Antje Gittel et al., and Alexander Tveit et al. for their papers in Applied and Environmental Microbiology and Frontiers in Terrestrial Microbiology! Both teams aimed to shed light on the role of microbes in carbon cycling in permafrost soils rich in organic carbon.

Tveit et al. studied the microbiota in peat soil of Spitsbergen (Norway), which emit large amounts of the greenhouse gases methane and carbon dioxide and identified the microorganisms responsible for the emissions using environmental genomics techniques.
Tveit A, Urich T, Svenning MM (2014) Metatranscriptomic analysis of Arctic peat soil microbiota. Applied and Environmental Microbiology 80(18): 5761. doi:10.1128/AEM.01030-14.

Gittel et al. applied molecular microbial ecology methods to characterise the microbes in cryoturbated soils of North-East Greenland.
Gittel A, Barta J, Lacmanova I, Schnecker J, Wild B, Capek P, Kaiser C, Torsvik V, Richter A, Schleper C, Urich T (2014) Site- and horizon-specific pattern of microbial community structure and enzyme activities in permafrost-affected soils of Greenland. Frontiers in Microbiology - Terrestrial Microbiology. doi: 10.3389/fmicb.2014.00541.

"Both studies contribute urgently needed information about the functioning of microbes in these vulnerable permafrost soils threatened by global warming" says Dr. Tim Urich, corresponding author of both papers.

"Wer lebt im Vulkan? - Von Urbakterien und anderen Methusalems"

Gestaltung: Anna Masoner
Sie leben an den verrücktesten Plätzen dieser Welt: in heißen Quellen, im Inneren von Vulkanen, auf Mülldeponien, im menschlichen Darm und möglicherweise sogar auf dem Mars. Die Rede ist von kleinen einzelligen Lebewesen mit Namen Archaeon. Wahrscheinlich gehören sie zu den ältesten Bewohnern der Erde. Die meisten Arten kommen ohne Sauerstoff aus, deshalb kann man sie etwa zu Methangasgewinnung in Biogasanlagen einsetzen. Christa Schleper, vom Department für Ökogenetik der Universität, hat schon viele der extremen Lebensräume der Archaea besucht. Den Ö1 Kinderuni Reporter/innen Peter, Boris, Daria, Alina erzählt sie, was die Winzlinge so faszinierend macht.

Mo, July 7, 2014, 07:05 p.m.
Gestaltung: Birgit Dalheimer

Zehn bis einhundert Billionen Bakterien bevölkern den Darm eines erwachsenen Menschen. Das sind ein bis zwei Kilogramm Mikroorganismen. Vor rund einhundert Jahren hielt man sie noch ausschließlich für zu bekämpfende Krankheitserreger. Heute ist bekannt: Sie sind an der Krankheitsabwehr beteiligt, beeinflussen das Immunsystem, helfen bei der Vitaminversorgung, spielen eine Rolle bei der Regulation des Körpergewichts und vieles andere mehr. Bei der Geburt beginnt die Besiedelung des Darms mit Bakterien, bis ins Erwachsenenalter tummeln sich einige tausend verschiedene Arten in Dünn- und Dickdarm. Lange wusste man wenig bis nichts über die mikrobielle Besiedelung des Darms. Das hat sich nicht zuletzt dank molekularbiologischer Methoden in den vergangenen Jahren geändert.
