EFC Working Party 10: Microbial Corrosion

Welcome to the website of the Working Party on Microbial Corrosion.

Current activities


Business Meeting

Next Business Meeting at the upcoming EUROCORR congress


Since EUROCORR 2011, the working party organizes a special session dedicated to BIOCOR, whose main focus is within two large industrial sectors: the oil and gas industry and the power supply facilities. Within these two sectors four research sub-programes were selected:

  • Water injection systems
  • Systems for handling stabilized oil
  • Cooling systems in energy facilities
  • Nuclear waste geological disposal

The main purpose of the working party is to increase basic understanding of biocorrosion. This general theme is organised in three thematic areas:

  1. Mechanisms of biocorrosion and analytical approaches
  2. From basic understanding towards knowledge-based risk assessment, monitoring and mitigation techniques
  3. From basic understanding towards new processes.

WP10 publications & Results from the Thematic Network "MIC of Industrial materials" and from biocor network

During 1998 to 2002 a Thematic Network on MIC of Industrial Materials was funded by the European Commission (BRRT-CT98-5084). The purpose of this network was to bring together scientists and engineers from European industries, research organisations and universities to promote scientific and technological co-operation in order to better understand microbiologically-influenced corrosion (MIC), sometimes termed biocorrosion, phenomena, to assess its' risk, and to propose effective ways of its' mitigation. The multidisciplinary character of the project requires promoting effective communication between all the different partners involved in the network. Comminication was organised according to three main areas:

  1. Enhancement of the relations between academic teams with different backgrounds (biochemistry, microbiology, electrochemistry, and materials) is necessary to improve the fundamental understanding of microbiologically-induced degradation and/or corrosion.
  2. Exchanges between engineers from different industrial sectors are strongly encouraged. Each of them possesses a particular know-how for MIC prevention in different application domains. Their techniques gain efficiency if they exchange their different experiences.
  3. To create multiple links between academic teams and R&D industrial groups. This provides the academic investigators with new specific MIC cases, on practical applications and at industrial scale. On the other hand, the connection with academic researchers helps the industrial partners to organise their own approach concerning fundamental well-identified topics and to define more efficient strategies against MIC.

From 2009 to 2013, the BIOCOR project was running with the purpose to provide the European Community with new multidisciplinary expertise in the area of biocorrosion in order to develop more efficient knowledge-based solutions for the industry. A summer school 'understanding biocorrosion: fundamentals & applications' was organized in 2011 by the University of Portsmouth (UK) and the courses were published as Number 66 in the EFC Series. Moreover the main contributions of EFC WP10 during Eurocorr 2012 were gathered in a special issue of Bioelectrochemistry (volume 97, 2014).

Previous Activities


1987. In January 1987, the inaugural meeting of the new EFC WP10 on Microbial Corrosion took place in Trondheim with Mr. Kenneth Tiller (UK) as its Chairman.

1988. The 1st EFC Workshop on Microbial Corrosion was held with support from Professor C.A.C. Sequeira and the local societies at Sintra (P) on 7-9 March 1988.

1994. Dominique Thierry (SCI, Sweden) took over the chairmanship of WP10 at the 3rd Workshop on Microbial Corrosion in Estoril. He promoted a survey of issues due to MIC in industrial environment and the European Program FP3-MAST II, leaded by Vittoria Scotto (CNR-ICMM, Italy), that screened the electrochemical effect of biofilm on stainless steel in different European Countries from 1992 to 1996. This action engaged a strict collaboration between several pioneers of microbial corrosion in Europe.

1999. At the 4th Workshop on Microbial Corrosion that was held in Lisbon, WP10 began assembling a directory of European Experts in Microbially Induced Corrosion (MIC) and helped to establish a European Network on MIC (BIOCORROSION-Microbiologically Influenced Corrosion of Industrial Materials, FP3-Brite Euram Program III, 1999-2003).

2001. Rolf Gubner (SCI, Sweden) succeeded Dominique Thierry as chairman of WP10. Since attention has been focused on by the organization of strong sessions at EUROCORR.

2009. A Marie Curie Initial Training Network (ITN) entitled BIOCOR has been funded by the EU Seventh Framework Programme "People". Initiated by the working party, it allowed the training of sixteen young researchers to address and manage all aspects of scientific and/or industrial problems related to MIC, running during four years under the coordination of Régine Basséguy (CNRS-Toulouse, F).

2012. Turid Liengen (Statoil, Norway),) took over the chairmanship of WP10 on behalf of BIOCOR

2014. Pierangela Cristiani (RSE, Italy), involved in the WP10 actions since 1999, at the end of BIOCOR action took in charge the chairmanship of the WP10.
