Outline of Final Research Achievements

Flame oxidation of the stainless steel anode was developed to enhance electrical power generation using microorganisms involved in the sulfur cycle. The flame-oxidized stainless steel anode enhances electricity production in microbial fuel cells, which is higher than that with the common carbonaceous electrode. Bacteria from the genus Geobacter were detected at a remarkably higher frequency in the biofilm formed on the flame-oxidized stainless steel anode than in the biofilms formed on the stainless steel anode and carbon cloth anode. The high performance of the flame-oxidized stainless steel anode could result from the particularly high population of bacteria closely related to G. metallireducens in the biofilm.
