Die single cell-ICP-ToF-MS kommt bei dem vorgestellten Poster bei der Analyse von Archaeen, die an mikrobiell beeinflusster Korrosion (engl. microbiologically influenced corrosion, MIC) von Stahl eine Rolle spielen, zum Einsatz. Mittels sc-ICP-ToF-MS wird die mögliche Aufnahme von einzelnen Elementen aus dem jeweiligen Stahl untersucht – die erhaltenen Informationen fließen zukünftig in die Aufklärung zugrunde liegender Mechanismen sowie Entwicklung möglicher Materialschutzkonzepte ein. Die Arbeiten Verknüpfen moderne Methoden der Analytical Sciences mit Materialien.

The single cell ICP-ToF-MS is used in the presented poster for the analysis of archaea involved in microbiologically influenced corrosion (MIC) of steel. By means of sc-ICP-ToF-MS, the possible uptake of individual elements from the respective steel is investigated - the information obtained will be used in the future to elucidate underlying mechanisms and develop possible material protection concepts. The work combines modern methods of analytical sciences with materials.

Microorganisms can take electrons directly from the metal surface (EMIC) thereby causing corrosion. Well known culprits of EMIC are: sulfate-reducing bacteria (SRB), acetogens and methanogens. Our aims - Develop a novel flow system to study MIC by methanogens to mimic industrial Environments - Investigate the inhibitory concentrations of biocides targeting SRB on corrosive methanogenic strains - Investigate the inhibitory effects of corrosion inhibitors on methanogens - Compare the inhibitory concentrations to SRB T2 - BAM meeting CY - BAM, Berlin, Germany DA - 06.06.2018 KW - MIC projekt KW - Mikrobiell beeinflusste Korrosion KW - Microbiologically influenced corrosion KW - Korrosion KW - Corrosion KW - Material degradation KW - Biocide PY - 2018 AN - OPUS4-46010 LA - eng AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany ER -
