Outline of Final Research Achievements

Alkaliphilic gram-positive microbe capable of extracellular electron transport (EET) was enriched and isolated from The Cedars spring at pH 12, using on-site microbial fuel cell system with anode connected with air cathode. Also, we developed a method to monitor the periplasmic proton concentration using the EET-capable microbe.
