Abstract: Effects of glycogen and glucose on the current outputs have been studied in photosynthetic bio-fuel cells using two kinds of cyanobacteria, Anabaena variabilis M-3 and Synechocystis sp. M-203, and 2-hydroxy-1,4-naphthoquinone. In the bio-fuel cell using Anabaena variabilis M-3, by repeating discharge-culture operation, the lifetime of the bio-fuel cell extended to net 80 hours, although the current output was sustained only for 10 hours under the condition of continuously running. In the case using Synechocystis sp. M-203, the current outputs both in the light and dark substantially increased by the addition of glucose to the anode solutions, indicating that glucose was transported into Synechocystis cells and was consumed to produce electricity.
