I have read the paper. They showed photosensitivity by both autoclaving the sample and adding DMCU to prevent photosynthesis. Both reduced power production. They do suggest a component of power production is related to electrolytic activity because they observe a dark setting power production; under a light setting the power production nearly doubles. They also discuss the possibility that the algae are just promoting the oxidation of the aluminum, but do a series of assays I don't fully understand and conclude that some of the current produced is most likely from the algae themselves.
