DOME partnership with
DOE Joint Genome Institute (JGI)
The DOE JGI has recently launched the Emerging Technologies Opportunity Program (ETOP) in order to develop partnerships with groups developing new technologies that DOE JGI could establish to add value to the high throughput sequencing it currently carries out for its users. Six initiatives were chosen including a project proposed by Michael Wagner and Roman Stocker from the M.I.T. (Boston, USA) entitled "High-throughput sorting of microbial cells with specific functional traits for single cell genomics by combining labeling with heavy water, Raman microspectroscopy, microfluidics and flow cytometry". JGI will invest approximately $3.5 million over the next two years in this and the other ETOP projects.

New paper in FEMS Microbiology Reviews
Novel avenues are available for the analysis of intestinal ecophysiology to yield new insights into complex host-symbiotic microbiota-pathogen processes, such colonization resistance against infections. This review summarizes bioinformatics tools for revealing hypothetical interactions from metagenomic data and highlights the value of gnotobiotic mouse models and new single-cell approaches for testing these hypotheses and studying the in vivo physiology of the gut microbiota.

New paper in PNAS
A DOME team encompassing David Berry, Alexander Loy, Arno Schintlmeister, Jochen Reichert, and Michael Wagner used NanoSIMS to identify
mucus-degrading bacteria in the mouse gut. Together with collaborators providing expertise in IR-MS measurements and animal experiments,
they showed that this important process is influenced also by non-degrading community members. The technique presented in this paper allows
for the first time direct functional investigation of microbes in the gut on a single cell level.

New papers in Environmental Microbiology and Frontiers in Microbiology
DOME teams around Michael Wagner and Holger Daims led two genome projects of nitrifying microorganisms representing lineages of global importance.
The ammonium-oxidizing archaeon Ca. Nitrososphaera gargensis is the first member of the so-called soil group or group I.1b whose genome was sequenced.
This analysis showed that these organisms are metabolically much more flexible than their marine counterparts. The second study reports on the genome
of the major marine nitrite oxidizer Nitrospina gracilis and demonstrates that this widespread organism represents a novel bacterial phylum challenging
its previous classification.

New paper in Genome Biology
In this international collaboration Ilias Lagkouvardos and Matthias Horn contributed the analysis of the impact of lateral gene transfer on the evolution of amoeboid genomes to suggest that in amoebae, lateral gene transfer is reflective of trophic strategy and driven by the selective pressure of new ecological niches.

Michael Wagner elected as fellow in the American Academy of Microbiology
The American Academy of Microbiology is the leadership group of the American Society for Microbiology, the world's oldest and largest life-science organization. Academy fellows are elected annually through a highly selective, peer-review process, based on their records of scientific achievement and original contributions that have advanced microbiology. As a fellow, Michi joins a group of eminent leaders in the field of microbiology recognized for their excellence, originality, creativity and exemplary careers in basic and applied research, teaching, clinical and public health, industry or government service. The academy relies on fellows for authoritative advice and information on critical issues in microbiology, from responding to congressional inquiries to organizing meetings and workshops.

New paper in Nature
Milucka J, Ferdelman TG, Polerecky L, Franzke D, Wegener G, Schmid M, Lieberwirth I, Wagner M, Widdel F and Kuypers MMM. 2012. Zero-valent sulphur is a key intermediate in marine methane oxidation. Nature doi:10.1038/nature11656
Markus Schmid and Michael Wagner contributed Raman microspectrometry analyses in this international collaboration to discover that the archaea responsible for the anaerobic oxidation of methane also reduce sulfate. Disulphide formed in this reaction is then consumed by deltaproteobacterial partners rendering the archaeal sulfate reduction more energy efficient. Thus, the metabolic model of anaerobic methane oxidation has to be revised by integrating the two newly described metabolic processes.
