Outline of Final Research Achievements

Based on some scientific research about the mechanism model of microbiologically influenced corrosion, a few original experimental set up functionally arranged as a macro cell. Then the possibility of the acceleration of corrosion reaction, i.e. the acceleration of electron flow o f experimental electric cell system were investigated.
Firstly, focusing on the abiotic corrosion inducers such as electric potential or chemical substances, the electron flow related to microbiologically influenced corrosion mechanism was investigated. Secondly, based on basic research some bacteria which can promote electric reaction was recruited, then the correlation of the bacterial activity and the electrode reaction was examined, moreover bacterial cultivating conditions to promote the reaction related to MIC. Then metabolism behavior of a microorganism (generation of a reactant/consumption) and the biofilm structure in the efficient condition of an electro chemical reaction were investigated.
