New paper in The ISME Journal
N2 fixation is an important process in photosynthetic microbial mats, but the contribution of different diazotrophs is still poorly understood. In an international collaboration, Dagmar Woebken, Faris Behnam, Arno Schintlmeister, and Michael Wagner showed that the cyanobacterium Lyngbya spp. is the most active diazotroph in microbial mats at Guerrero Negro, Mexico. Furthermore, the effect of CARD-FISH on the isotopic composition of microbial cells in SIP-NanoSIMS investigations was elucidated.
A preprint will be available shortly.

Michael Wagner Highly Cited Researcher in Microbiology
Thomson Reuters has generated in 2014 a new list of Highly Cited Researchers in the sciences and social sciences. In total 114 microbiologists earned this distinction. Among them less than 30 are working in Europe and Michael is one of two highly cited microbiologists working in Austria. In the 22 research fields analyzed over 3000 scientists were identified as Highly Cited Researchers, 20 of them have their primary affiliation in Austria.

Austrian microbiology prize for David Berry
David was awarded the prize from the Austrian Society for Hygiene, Microbiology and Preventative Medicine (ÖGHMP) in recognition of a study he performed together with Alexander Loy and colleagues from the Medical University of Vienna. In the study, which was recently published in American Journal of Gastroenterology, fecal microbiota transplantation was evaluated as novel therapy for individuals with ulcerative colitis.

"We all start out as scientists"
"Science is passion, vision, and life and none of that is necessarily synonymous with sacrifice", says Celine Lesaulnier who received a Back-to-Research Grant from the University of Vienna, supporting researchers who reduced or interrupted their academic research in order to care for their children.

Invading the nucleus of amoebae
In a new paper published in the ISME journal, Frederik Schulz, Matthias Horn and co-authors describe the discovery of a bacterial symbiont with an unusual intracellular niche. Within few hours after infection the bacteria have invaded the amoeba nucleus, where they mutliply with surprisingly little effect on host fitness. This microbial association is an ideal model system to further investigate evolution and molecular mechanisms of the rare phenomenon of intranuclear symbiosis.

New Paper in The ISME Journal
If the biogeography of microorganisms in the environment is also determined by limitations in passive dispersal is still under debate. By using endospores of thermophilic bacteria in cold marine sediments as indicators, Albert Müller and Alexander Loy now show that marine microbial biogeography is indeed impacted by geographic dispersal barriers such as limited connectivity of local water masses to world ocean circulation.

New Paper in Nature Communications
The majority of bacteria possess a peptidoglycan sacculus consisting of a disaccharide backbone crosslinked by peptide chains, which is crucial for cell division, maintaining cell shape and resisting osmotic stress. Whether chlamydiae contain this structure has long been debated, but in an international collaboration Karin Aistleitner and Matthias Horn now show that the amoeba symbiont Protochlamydia amoebophila does synthesize peptidoglycan.

New collaborative large-scale project with the JGI
Michael Wagner and Holger Daims together with members of the Joint Genome Institute will sequence and analyze the whole genome amplification (WGA) products of 100 nitrifier microcolonies from a single activated sludge sample. The microcolonies will be identified by Raman microspectroscopy and sorted by optical tweezing for WGA. The major goal of this project is to understand the evolutionary history and ecological consequences of nitrifier microdiversity. This project will be funded in the framework of the community science program (CSP) of the JGI.

New paper in the American Journal of Gastroenterology
Together with colleagues from the Medical University of Vienna, Alexander Loy and David Berry explored if and how fecal microbiota transplantation support microbial recolonization of the gut of ulcerative colitis patients. They show that temporal bacterial community dynamics and therapy success varied strongly among individual patients that received this unusual treatment.

New Paper in PLoS Pathogens
Chlamydial elementary bodies have mostly been thought of as dormant, spore-like particles. However, Barbara Sixt, Alexander Siegl, Matthias Horn and colleagues now demonstrate metabolic activity in chlamydial elementary bodies that is linked to infectivity. Challenging textbook knowledge, these results suggest that the infective stage is much more dependent on its environment (and thus potentially vulnerable) than previously recognized.
