Biolfim Centre participates in Wissensnacht Ruhr 2018

WissensNachtRuhr” (Science Night Ruhr) is one of the largest Science Festivals in Germany, which takes place every two years. During this evening, scientists from institutions of the Ruhr area offer diverse activities directed to families, students and everybody interested in research and science. This year, “WissesnachtRuhr” took place on the 28th of September and the Aquatic Microbiology department was present. 

Our very own team of science communicators, Ivana Kraiselburd, Meike Arnold, Ianina Kaplieva-Dudeck and Lisa Kroll hosted an interactive stand at “Haus der Technik” in Essen, where visitors were able to extract DNA, observe microorganism under the microscope and discover which microbes are growing in their skin and in every-day objects like phones.

Larissa Schocke won the poster prize at ISE

Larissa Schocke won the poster award of the International Society for Extremophiles at the Extremophiles Conference 2018 in Ischia, Italy. The poster was titled "Impact of protein phosphorylation in the thermoacidophilic crenarchaeota Sulfolobus acidocaldarius DSM 639".

14.08.2018 Two prizes for nanoremediation laboratory

The nanoremediation laboratory of Prof. Dr. R. Meckenstock recently has won two prestigious prizes. On July 13th, at the graduation ceremony of the ninth round of the founding competition of GRIID (GründungsInitiative Innovation Duisburg), Dr. Beate Krok, together with Dr. Sadjad Mohammadian and Prof. Dr. Rainer Meckenstock, won the first prize for the best business plan. The business plan was developed during the Small Businiess Management (SBM) course. 

In addition, REGROUND project has been awarded to attend first phase of the EIT Raw Materials' accelerator program. The team will receive €15K as a funding to cover their costs for participating in this Accelerator Program from September to December 2018.

15.07.2018 New paper on Arsenic removal from Groundwater

n the framework of REGROUND project and in collaboration with the Katholieke Universiteit Leuven (KUL) and Friedrich-Schiller-Universität Jena (FSU-Jena) a new paper is published. The paper present a quantitiave analysis on the effectiveness of Humic-acid coated goethite nanoparticle in removal of Arsenic from contaminated groundwater. The paper can be accessed from this link

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.

23/03/2017 Successful defense
