Biodegradation of ballast tank coating investigated by impedance spectroscopy and microscopy

This research paper addresses the biodegradation process for ballast tank coatings in marine environments. As part of this new approach, a commercially available ballast tank coating was exposed to bacteria obtained from a culture collection and to a natural bacterial community isolated from a real ballast tank. The natural community was chosen...

Ship ballast tanks a review from microbial corrosion and electrochemical point of view

Microbiologically Influenced Corrosion (MIC) is the term used for the phenomenon in which corrosion is initiated and/or accelerated by the activities of microorganisms. MIC is a very serious problem for the ship industry as it reduces structural lifetime in combination with safety risks for crewmembers or inspection personal and increases...

Microbiologically influenced corrosion in ship ballast tanks

Study of MIC impact in a full-scale ship ballast tank

Microbiologically influenced corrosion (MIC) of steel is a serious problem in the marine environment and many industries, such as the shipping industry. While electrochemical measurements such as impedance have been used in corrosion monitoring for several years, the true capabilities of the technique and the optimal methodology for extracting...

A new approach to study local corrosion processes on steel surfaces by combining different microscopic techniques

Corrosion studies of materials on the micro or even nano-scale level are cumbersome due to instrumental limitations and handling procedures. If biological processes are involved the spatial resolution is even more important and sample preparation is usually the limitation. Attachment of bacteria on stainless steel surface is a complex...

Experimental investigation into the effects of ICCP and scale formation on MIC on HSLA steel

EIS study of MIC in three different zones derived from ship ballast tank model system

Microbiologically influenced corrosion (MIC) is a well known phenomenon in aquatic environments [1]. The presence of a biofilm on metal surface often establishes new electrochemical reaction pathways, or promotes reactions which are not normally favored in the absence of microorganisms, resulting in increased corrosion rates and on the...

Temperature effect on the sulfur isotope fractionation during sulfate reduction by two strains of the hyperthermophilic Archaeoglobus fulgidus

Summary Sulfur isotope fractionation during dissimilatory sulfate reduction by two strains of the thermophilic archaeon Archaeoglobus fulgidus (strains VC-16 and Z) was explored over the entire temperature range of growth. The optimal cell-specific sulfate reduction rate (14 fmol cell-1 h -1) was found at 82-84°C but growth was measured as low...
