02.02.2018 Hundreds of novel organisms from the deep subsurface

Several hundred novel microorganisms were discovered in groundwater fluids sourced from the deep terrestrial subsurface of the Colorado Plateau. Lead by Alexander Probst (now the Head of Group of Aquatic Microbial Ecology), scientists of the University of California, Berkeley, collaborated with researchers from the University of Calgary and the Joint Genome Institute to apply microbial source tracking based on hydrogeological measurements. They discovered a stratification of microbial metabolism and diversity throughout the subsurface and postulated a symbiotic interaction between two uncultivated archaea that comprise most of the biomass in this subsurface system.

06/04/2017 Philip Weyrauch wins poster prize

Philip Weyrauch was awarded with the Microbiology Best Scientific Poster Prize in the Environmental and Applied Microbiology Forum category with the poster “Elucidation of a dearomatising reductase reaction involved in anaerobic degradation of naphthalene” at the Microbiology Society Annual Conference 2017, Edinburgh, UK.

In the presented work we elucidated the 5,6,7,8-tetrahydro-2-naphthoyl-CoA reductase reaction in cell free extracts of sulphate-reducing naphthalene degraders by testing different electron donors. Our data indicate that the reduced ferredoxins required for this reaction are delivered via a 2-oxoglutarate:ferredoxin oxidoreductase and that the downstream pathway proceeds via β-oxidation-like reactions with water addition to hexahydro-2-naphthoyl-CoA.
