TY - CONF A1 - Koerdt, Andrea T1 - The Power of networks – COST Action CA20130 N2 - For optimal research on microbiologically influenced corrosion (MIC), balanced and interdisciplinary cooperation is extremely important. However, differing perspectives, thought processes, and even variations in nomenclature/terminology often hinder the establishment of effective collaborations. Over the past four years, COST Action Euro-MIC (CA20130) has effectively addressed these discrepancies. Through regular meetings, conferences, and scientific exchanges, a large international network has been established. Many scientific findings and results have been achieved through scientific, interdisciplinary exchange within the international network. The upcoming presentation will highlight three examples (among many others) that have resulted in successful collaborations, third-party funding applications, publications, or outstanding results and emphasize that successful results in MIC research, facilitated by an interdisciplinary network, can lead more quickly to meaningful and application-oriented findings. Project 1&2 describe two different kinds of Projects related to the use of Nanoparticles; one is about the efficacy testing of novel Nanoparticles. Project 2 deals about how to apply already working and tested nanoparticles to different materials and conditions. Project 3a is related to the energy sector; a crucial part of our society, and currently undergoing significant changes. Climate change, rising temperatures, increased use of fertilizers and other environmental pollutants have led to an increasing occurrence of microorganisms and contamination in some sectors. But how we deal with “baggage” from the past and store nuclear waste without harm or risk for human and environment, but also how to transfer the gained knowledge to areas like safe Hydrogen storage in geological underground formation.

Unlike the USA, Canada, and Australia, Europe has less developed cooperation on MIC. Although several research groups and industrial stakeholders are addressing MIC, discussions remain fragmented, and information exchange is limited. A truly transdisciplinary approach is rarely seen. As a result, Europe often relies on methods, preventive measures, and standards from other regions, as there are no equivalent European standards. This situation makes Europe a) highly dependent, and b) in some cases, unable to use certain measures or standards due to European legal restrictions (e.g., the use of biocides). In 2021, researchers established the “Euro-MIC” network, financially supported by the EU project “COST-Action,” to tackle these issues. Through COST-Action, Euro-MIC aims to facilitate necessary interactions, communication, knowledge sharing, and training for personnel and researchers across various disciplines. COST-Action supports network activities, workshops, training schools, conferences, and more. Euro-MIC aspires to position Europe as a leader in MIC, promoting ideas on par with other nations while upholding European values and ensuring greater protection for people, property, and the environment. In this presentation, I will briefly introduce the principles of COST Action and highlight the significant opportunities provided by this EU-funded project. COST Action fosters interdisciplinarity, networking, training, scientific exchange, and the promotion of young scientists. By showcasing some examples of CA20130 COST ACTION Euro-MIC, I hope to demonstrate that COST Action is not only relevant for addressing MIC but can also be applied to other important topics and sectors.

MIC describes the negative effects a material can experience due to the presence of microorganisms. In Europe, several research groups/ other industrial stakeholders are already dealing with MIC. Unfortunately, the discussions are fragmented and the exchange of information is limited. A true transdisciplinary approach is hardly ever experienced, although this would be logical for this material/biology related challenge. USA, Canada and Australia have strong networks, and develop methods, prevention measures and standards, which Europe is forced to use, since nothing similar exists for a network and combined knowledge to design them according to european standards. This makes Europe extremely dependent and, in some cases, the potential measures or standards cannot been used because the suggested solutions are prohibited by European laws (e.g. use of biocides). Therefore, it is important to initiate a new European MIC-network. Europe needs to combine the efforts as experts in different fields and develop prevention measures according to the European rules, in close cooperation with industry and plant operators and owners of critical infrastructure. This COST Action will provide the necessary interaction and communication, knowledge sharing, training of personnel and of researchers of different disciplines. This will bring Europe to a leading role in this process, bringing ideas on an equal level with other nations, considering the values which are important for Europe and attitudes (e.g.environmental protection) and representing greater protection for people, property and the environment. The main aim and objective of the Action is to , in the context of MIC-research/control, encourage a fluent/synergistic collaboration/communication, closing the gap between materials scientists, engineers, microbiologists, chemists and integrity managers to encourage sufficient interaction between academia and industry. This Action will create a common MIC-Network, including the important stakeholders.

T1 - Microbiologically Influenced Corrosion (MIC) by Halophilic (Salt-Loving) Nitrate and Sulfate-Reducing Microorganisms N2 - The survey of Canadian shale sites showed a dominance of halophilic microorganisms, including Halomonas (HA). Nitrate-amended incubations of the field samples under high salinity (14.6% NaCl), revealed a dominance of HA (>72%) and an accumulation of nitrite. Nitrite accumulation directly inhibited the growth of SRB, thereby decreasing their souring and corrosion risks. However, accumulated nitrite may also contribute to iron corrosion, which will be tested by using different concentrations of nitrate as an electron acceptor to HA. Different salinities are further tested on HA strains supplemented with iron coupons to determine their effects on iron corrosion rates. HA incubated with separate cultures of corrosive methanogen and SRB were tested to determine whether a positive or adverse effect will occur between them. Lastly, analyses of iron coupons will be conducted using TOF-SIMS, FIB-SEM and EDS for corrosion product characterization T2 - Corrosion 2021 CY - Online Meeting DA - 19.04.2021 KW - MIC KW - Bacteria KW - Halophile KW - Corrosion KW - Environmental condition KW - Korrosion KW - High salinity PY - 2021 UR - https://my.nace.org/PaperTrail/Authors/Submission.aspx?id=2914f145-7f8f-ea11-813a-005056a95a7c SP - Paper C2021-16284, 1 AN - OPUS4-52479 LA - eng AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany ER - TY - CONF A1 - Koerdt, Andrea T1 - Wasserstofflagerung in unterirdischen geologischen Formationen und potenzielle Risiken durch Mikroorganismen N2 - Bei dem Vortrag werden die potentiellen mikrobiologischen Einflüsse im Falle der Lagerung von Wasserstofflagerung in unterirdischen geologischen Formationen vorgestellt, die Zusammenarbeit mit internen und auch externen Partnern.

Standard laboratory MIC testing using static serum bottle enrichments is an easy but limited method, offering poor resolution on the biomineralization process of corrosion products. An example of this is the presumed corrosion product siderite by corrosive methanogens (Mi-MIC). Previous publications reported siderite was the sole corrosion product of M. maripaludis using metal coupons incubated under stationary conditions. However, the formation of siderite is closely related to the surrounding environmental conditions, i.e. pH, CO2 concentration, flow and temperature. Thus, siderite as the sole corrosion product of Mi-MIC remain inconclusive and questionable. To study Mi-MIC effectively, a novel versatile multiport flow-column corrosion monitoring system (MFC) was developed. MFC allows sectional corrosion rate determination under flow conditions using different types of material, inoculum and packing material. MFC offers great flexibility, ease of operation and accurate corrosion measurements that can be combined with many other techniques. Using MFC, we studied multiple strains of methanogens and compared it with sulfate-reducing bacteria under neutral and low pH conditions. It was revealed by MFC that corrosive methanogens have equally high corrosion potential as sulfate-reducing bacteria. Additionally, siderite is not the dominant nor sole corrosion product of Mi-MIC. Thus, effective corrosion monitoring and establishing standard laboratory practices, i.e. incorporating MFC as part of regular testing process, will provide deeper understanding of MIC. This will allow further microbial electrophysiology understandings, contributing to effective mitigation strategy development.
